Title: aeon labs energy meter G2
Post by: wo984c on May 12, 2013, 11:48:15 pm
I don't find the usb port in this new version. Any idea?
It detects the master and clamps as generic IO. The problem should be related to the firmware.

I had the same problems as you with my 3 clamp generation 2 energy meter.

I got it working doing this (device window/Advanced tab):
  1) Change device-type to: urn:schemas-micasaverde-com:device:PowerMeter:1
  2) Change device_file to: D_PowerMeter1.xml
  3) Change category_num to: 21 (I am not sure if needed but my other HEM gen1 have this number)

Change these values in main device window and in all clamp windows and save changes. Reload and now you should have almost working energy meter. After that open main meter window and go to Device Options tab and add Configuration settings. My settings are in attached picture. If you don't have 3 clamp meter then you should change value for variable 101. You can find more info from this: http://forum.micasaverde.com/index.php/topic,3366.msg94937.html#msg94937

I still have some minor problems. Main energy consumption (main device window) is not updating in the same time as clamps, it takes some time. Problem is probably that my unit has firmware 3.40. (I have also gen1 unit and it is working after I updated its firmware to version 3.67).

So I would also like to know how to update firmware for generation 2 HEM, there are no USB port??

Did you slide off battery cover and look inside for usb port?

Gen2 HEM don't have battery cover, you can't use batteries.

A lot of this helped thanks! I had a horrible problem with my Vera when I set parameter 3 = to 0 though, this caused a repeating LUA crash and the orange light would not stay lit, this pretty much broke my Vera until I turned off the HEM, rebooted my Vera, put it in exclude mode, turned back on the HEM and immediately pressed the Z-wave button to exclude it. Then included it back, and immediately set 3 = to 1. Note that the HEM remembers 3 = 0 after excluding it from the network, so just doing this alone wont fix anything.

For the record I could not find a USB port anywhere on my G2, I even unscrewed the back cover and looked at the circuit board, which did not appear to have any USB connection whatsoever. Very irritating, as I feel a newer firmware could have prevented a lot of this need to set custom parameters.

Thanks to the helpful information here I also got my Aeon Energy Meter G2 (DSB28-ZWxx) working with these instructions.

- changing Device Type, Device File, Category
- changing parameters 101, 111, 4,5,6
- I did not change parameter 3 since someone else reported an issue with it.

Now my Energy meter reports fine, EXCEPT the KWH value on the "parent" device fluctuates.
e.g. Clamp 1 reports 0.5 KWH, Clamp 2 reports 0.2 KWH, and the Main HEM reports either 0.7 KWH (which is correct) or something like 122 KWH (way off?.)

This switches back to the right value occasionally, but mainly the KWH reading of the main (parent) HEM stays at the wrong value.
Has anybody else experienced this and found a solution?
Could it be that I have to set parameter 3 explicitly to 0?
The other reading seem to update based on the time interval I have set (10 secs.) and seem to be correct.

Thanks,
Mike

Same problem here and I have not found how to correct it.

However I am quite satisfied to the meter. If I add clamp readings together (3 clamp meter) I get value which is quite accurate compared to my electricity company value (value that they are invoicing me). Difference is only 1 to 2 %.

Today total sum kWh value is 892 kWh (electricity company value is 908 kWh). Probably one day is missing from meter value compared to company value, so readings are quite good.

Main value on the ?parent? device is about 225..232 kWh. It is also fluctuating but it has never been over 300 kWh (I have not seen bigger values). Total watt reading seems be be correct.

Post by: mikewop on November 04, 2013, 06:19:38 pm
Thanks Jukka for confirming this.
Now I am not sure if this is an issue with Aeon Labs or with VeraLite/Mios.

Is there a way to log the raw values that the Aeon HEM reports to MiCasaVerde?
If it's an issue with AeonLabs, I'd like to report it to them and get it resolved hopefully.
I am quite new with VeraLite, just set it up yesterday, so forgive the noob question.

Thanks,
Mike

I have a G2 2 clamp meter (3.64) and have the same KWH problem. The parent reads crazy high KWH, but the Watts is correct.. The clamps read correct KWH and watts.

For the watts to read correct, I have 1 set to 120 while I have a 220 system here in China. But I think this is because actually each power leg is really 120v coming into my bus. I'm not a sparky, but this is my guess.

The KWH is off the wall and it would be nice to find a solution. I just reset the KWH 5 minutes ago, and it is reporting 1532KWH used!

Try setting Parameter 101 to 6915 (I have a US 2-Clamp version).
With that setting the kWh seem to be stable and correct here for me.

I stumbled across this by accident. I have the values reporting every 10 seconds, and so far it has been correct

Here are my parameter settings:

Parm 3: 7
Parm 4: 20
Parm 5: 10
Parm 6: 10
Parm 101: 6915
Parm 111: 10

With these settings the values are accurate for me and update pretty quickly (within a few seconds).

As soon as I change parm 101 to something > 6915, then the kWh reading starts to fluctuate again.
Also I cannot really verify that the "delta" detection works, I set the threshold to 10W/20W but I cannot really tell if it works

It seems to me that maybe the document referenced here: http://forum.micasaverde.com/index.php/topic,3366.msg94937.html#msg94937
is not 100% applicable for the HEM Gen2 that we have. It seems the parameter 111 is behaving differently.

Does anyone have experience with the Aeon Labs Tech support? It would be great to get an accurate config document for the HEM Gen2 hardware.
Title: Re: aeon labs energy meter G2
Post by: mikewop on November 22, 2013, 10:53:51 am
Quick update here:

So it seems the Aeon Labs Energy Meter G2 (DSB28-ZWxx) has the bits for parameters 101-103 shifted around because:
- it does not have a battery
- it can also report V (Volts) and A (Amps) it seems (which is pretty cool actually)

I got this information from Aeon Labs Tech support.
I don't think the V and A fields are supported by the MiCasaVerde implementation yet, so in my case as soon as I set a bit that corresponds to the voltage setting, the kWh value starts to fluctuate.

So the right parameter value for Parameter 101 at the moment is 6915.
That produces stable and correct kWh readings for me.

Aeon Labs is still looking into a bug related to reporting the voltage and amps.

Now the next question is, what and how needs to be modified (D_PowerMeter1.xml?) in order to include the Volts and Amps field in the UI?
I am pretty new at this, but I might give it a try over the next few days.

Hope that helps,
Mike

Very new at this.  Have 2 G2's (DSB28-ZWxx) on 2 panels (both US 2 clamp models).  Sporadic results.  Never been able to get all the clamps to read both the Watts and the KWH.  Initial install had all the Watt readings but not all the KWH for all the clamps.  Latest reinstall has all of the KWH but still missing the Watts on one clamp (it does show the KWH).  Have never been able to adjust any parameters...get "Failed at: Setting user configuration" every time I attempt that.  Trying to adjust parameters through Device Options tab as shown on the attached picture...is that correct.  What am I missing?

Thanks in advance for any help.

Hi "AnotherRookie",

from looking at your screen shots, in the "CurrentValue" column it seems to me that the HEM never really got updated with your settings.
I had the same error "Failed: setting user configuration", it seems the HEM is pretty sensitive about good network connectivity.
Try to move your Vera/VeraLite closer to the HEM temporarily and then do a "Configure Node Right Now" until that is successful and the values in the "Current Value" column match the values in the "Desired Value" column.
After that is successful, you may want to turn the auto-configuration off (on the "Settings" tab set "Automatically configure" to "no"), so that it doesn't try to reconfigure the HEM anymore.
Also I have since learned from Aeon Labs Tech support that the Parameter 3 should be set to 0 for this unit.
Attached are my current settings that are stable for me.
(Not 100% sure if parameters 4,5,6 really matter if parameter 3 is set to 0, but they don't seem to hurt it either).

Hope that works!
Mike

Thanks for the feedback Mike.  I have placed the Veralite next to the meters.  I have removed and reinstalled the devices, but I cannot get the parameters to change...always get the same "Failed at: Setting user configuration" message when trying to change a parameter.  I have Version 3,3,40,1,12.  Could that be the problem?  Has anyone found out how to update the firmware on this device without a USB connection?

As an update, I have 2 of these 2-clamp devices on 2 panels next to each other.  I have removed and reinstalled several times.  Now, it appears that both devices may be reporting the Watts and KWH for the mains, but for each Clamp, I think they are reporting the voltage in the KWH position and nothing under Watts.  I say I think it is voltage because all 4 clamps have been reporting in the 122.5 to 124.5 range for KWH.

Can you post what value you have for 103? I think I set it incorrectly.

Title: Re: aeon labs energy meter G2
Post by: mikewop on November 24, 2013, 10:15:52 am
Hello "AnotherRookie",

Sorry to hear you are running into so many issues.
My firmware version is 3.3.40.1.12

I now remember that I got the configuration error also when one of the parameters was wrong. It seems the HEM does some internal validation when saving.
So maybe some parameter got set to an invalid value at some point (maybe even due to a network glitch at the time) and not it doesn't take any new config.

One more thing you could try: reset the HEM to its factory default configuration:
From the documentation:
"
1. Make sure the HEM G2 has been connected to the power supply
2. Press and hold the Z-Wave button for 10 seconds
3. If the HEM G2 LED blinks slowly, it indicates reset success, otherwise please repeat step 2.
Note: Reset HEM G2 to factory default settings will:
- sets HEM G2 to not in Z-Wave network state
- delete the association setting and power measure value
- restore the configuration settings to the default
"

Disclaimer: I have not tried this myself, but I copied this straight from the engineering document.
(There is a draft engineering spec for the HEM G2 but I cannot post it here as per request of Aeon Labs. But they said they would give the document if a user directly requests it - contact their tech support).
On another note, I think you are correct, the value you see is the voltage reported in the kWH field. The G2 seems like it actually can report voltage and Amps, and this maybe a bug in the current firmware. As son as I had the bit set for voltage (in the parameter 101), the values would switch between kWh and 122.xxx,
Aeon Labs said they were able to reproduce this, but maybe you might want to contact them too to get some more traction. In any event, you probably need to get your config working first.

PS: I would try all of this on one of your meters first, unplug the other one for the time being to rule out any interference. Try to get one of them to work first.

Let me know how it goes...
Mike

When I first configure my HEM GEN2 I didn't use parameter 103 at all. Only parameter 101 was modified. Today I use also parameter 103 and it is the same as parameter 101. However it didn't change anything.

When I read above post I realized what my total fluctuating kWh reading is (thanks mikewop and AnotherRookie). It is the voltage reading. We have here 240 V nominal voltage. My summer cottage is almost in the end of power line and therefore the voltage value is lower due to long line (225..232V).

bucko thanks for searing this information. I have tried to find that kind of table where the bits are explained but I didn't found any documentation from the internet. Table that you posted are quite different than I have for GEN1 model (parameter 101-103).

If I use this new GEN2 table I get value 16131 for parameter 101 (3 clamp model). Same value for GEN1 model was 16140. I think that reserved columns 5 and 2 are used for clamp 3.

I can't test this new value now. My HEM GEN2 device is in my summer cottage and now we don't have power on (winter time). I have to wait next spring to test this new value.

Post by: bucko on December 02, 2013, 09:12:40 pm
This is the way to make parameter changes to the HEM successfully. Follow these steps to insure the parameters are locked in.

1. DO NOT CHANGE ANY OF THE HEM NAMES!
2.First set 111~113 to stagger report times so they do not conflict, ex. 111= 30. 112=60, 113=90. Don't go faster than 30 sec.
3.Change 1 parameter at a time. Do...
A. Change parameter and Save Vera. If you see a Failed to config then the parameter number you just used is not a correct number. Go back and correct.
    If you see no error then open HEM to settings and click "Config node now". This will actually set your parameter in the HEM. Save does not set the number in the         HEM!
B. Then open Device Options and verify that the parameter number matches the set number. Now you know the HEM program took.
4. Now reset the HEM unit. I made a scene with this luup code:

local meterID = <ID>
local kwh = luup.variable_get("urn:micasaverde-com:serviceId:EnergyMetering1", "KWH", meterID)

luup.call_action("urn:micasaverde-com:serviceId:EnergyMetering1", "ResetKWH", {}, meterID)

5. Watch for several minutes to see if the HEM works as expected.

Do this for each parameter change.
You cannot change the parameters for the clamps. Only the HEM unit will program.

I was able to get the meter to work really well using the document that bucko posted.  101, 102, and 103 are all individual delivery groups and the 4 byte dec number determines which values are sent in each group.  Each of the groups send their values based off of the times set to 111, 112, and 113 respectively.  I have the 2 clamp G2 until and used the following setting:
101 set to 770 (this sends only the power values for phase 1, phase 2, and the total)
111 set to 10 (this is the minimum time - any less and the device with give an error)
102 set to 6145 (this sends the KWH for all three values)
112 set to 60 (who needs the KWH updated more often than every minute, I should probably set it to 300 seconds instead)
103 set to 0 (this eliminates any current or voltage readings from being sent)

When someone figures out how we can use the current or voltage readings I can give the number that enables them.  Hopefully someone will find a way because I use dataMine to log all of my power values and would love to record the current and voltage also.

I have a G2 2 clamp meter (3.64) and have the same KWH problem. The parent reads crazy high KWH, but the Watts is correct.. The clamps read correct KWH and watts.

For the watts to read correct, I have 1 set to 120 while I have a 220 system here in China. But I think this is because actually each power leg is really 120v coming into my bus. I'm not a sparky, but this is my guess.

The KWH is off the wall and it would be nice to find a solution. I just reset the KWH 5 minutes ago, and it is reporting 1532KWH used!

Bucko -How did you change the voltage on G2?  variable 1 is missing on G2.  I tried to add it but it did not work.  I need to change the voltage from 120 to 240 because the meter is on my solar system.

I am not sure that you would need to change the voltage since the unit appears to measure the voltage from the source that it is connected to.  Plus if you have a 240V solar system that just means you have 2 120VAC phases and need to use a two clamp G2 meter to measure them.

Bocko - I only log the instantaneous power usage in data mine not the kWH.  I mainly use it to determine how often my 3 AC units and 2 water heaters are active.  I have 2 of the heat pump units on the Trane Z-Wave thermostats and they won't tell you when the system is running so I use the power to figure that out.

AZEngineer / Bucko- thanks for your input - My solar uses micro inverters so I have two 240v homeruns coming into my panel and I have a ct clamp on each homerun.  The HEM G2 does not have parameter 1.  I contacted AEON Labs and they informed me that the US version is 80V-150V  and measures volts so it is not configurable.  I asked if they could modify the US or EU version to work (run the EU config on US HEM) and they are working on it.  I am going to test the TED 5002-G also to see if it may be a better solution.  The HEM G2 is a much better meter from the G1 as it seems to report much more accurately - the G1 always had a phantom load.   Thanks again

Post by: AZEngineer on December 16, 2013, 02:10:16 pm
AnotherRookie,

Do your 240VAC lines measure 240 when measured from phase to phase (hot wire to hot wire) or do they measure 240VAC from one wire to ground?  I suspect that they are just like standard household inputs and much like the solar system that I have on my house where the wires are at 240VAC when measure between the two hot wires but only at 120 when measured to ground.  If this is so then you don't need any changes to the system and it will work as is with each clamp around the separate phase wires coming into you breaker box from your micro inverters.  I am fairly sure about this because here in the US we don't usually use anything more than 120V per phase on residential applications.

If I am completely missing something and it really is single wire 240VAC to ground lines then I am not sure if 120VAC or 240VAC would make a difference since current is current.  You could probably use the meter as is to measure the current and then calculate the power based off the known voltage.  There is probably a way to multiply the variables by 2 to correct for the 240VAC voltage if you really need to.

If all else fails send me a message and I can try to help you offline.

How are you guys physically connecting your meters?

I've just received one of these in the UK (single phase 240V), I ordered the 3 clamp version and was expecting the battery powered one with just the clamps on, so I could monitor 3 separate loads.  In my house I have the main electricity feed split between house and workshop,  I currently use a currentcost to monitor the total, house and workshop separately.  I was hoping to replace the currentcost with the Aeon.

This GEN2 version has 3 clamps and 3 bare 2-core flex on it, and seems to actually be aimed at a 3 phase installation.  Anybody know if / how I can make it work in my situation?


Thanks,

Martyn

AnotherRookie,

Do your 240VAC lines measure 240 when measured from phase to phase (hot wire to hot wire) or do they measure 240VAC from one wire to ground?  I suspect that they are just like standard household inputs and much like the solar system that I have on my house where the wires are at 240VAC when measure between the two hot wires but only at 120 when measured to ground.  If this is so then you don't need any changes to the system and it will work as is with each clamp around the separate phase wires coming into you breaker box from your micro inverters.  I am fairly sure about this because here in the US we don't usually use anything more than 120V per phase on residential applications.

If I am completely missing something and it really is single wire 240VAC to ground lines then I am not sure if 120VAC or 240VAC would make a difference since current is current.  You could probably use the meter as is to measure the current and then calculate the power based off the known voltage.  There is probably a way to multiply the variables by 2 to correct for the 240VAC voltage if you really need to.

If all else fails send me a message and I can try to help you offline.

AZEngineer-

AEON Labs is working on this with their engineers.  I moved the HEM G2 to my mains to use it as a net meter.  It does not seem as though the CTs are bidirectional and I only see positive watt readings even when I am exporting.  I tried all combinations of CT configurations with no change.  I contacted AEON who is looking into the matter. 

Out of frustration I ordered and installed a TED 5002-G and downloaded the TED plugin.  This unit is great and worked out of the box.  It also provides more info then that of the HEM.  Hopefully HEM will catch up soon.

Thanks

Dear forum,
I just purchase a DSB28-ZWUS and I am unable to pair it with my Vera3. Currently I do not have the HEM clamps connected to the power panel but the unit is plugged into 110 vac. I see the red led blink when attempting to pair but Vera doesn't grab it.

Any ideas ?

Many thanks for any help

Dear Forum,

Contacted Power Monitor supplier support and they advised the following. Go to last option of add devices ( advanced Z wave devices ) and scroll to the bottom. Change include toi exclude and timing to 90. Hit GO. Ensure Vera is responding. Now go back and change exclude to include and hit GO. Now press and hold the pairing button on the Power Monitor. Power monitor should blink rapidly. If it doesn't stop blinking, hit the pair button twice. My unit immediately paired with the Vera.

Hope this helps.

I was able to install my power meter which is about 25 feet from my Vera 3 and add it using option 1.  I think the 3ft away rule is nonsense.  I have added all sorts of devices without moving the Vera closer to them.

I did have a connection problem once with the HEM v2 that kept me from being able to register the device and if fixed that problem by preforming a reset of the HEM by holding the button down for 30 seconds or so.  After resetting the HEM and using the correct device configuration values I haven't had any problems.

Good luck...

Hi
excuse me for my english :o

I have the 2 clamps european edition of this meter. I live in Spain (1wire+neutral). Standard voltage at 230v.
My power meter works perfectly.... at half load.

If I put for example a 150w lamp, it detects only 75. Put the 40w lamps, detects only 20. etc.
I think the power meter is prepared to install with 2 clamps in the main line. In the instruction's picture explain how put this, but don't work me. I think the only solution is can change the main voltage (I supose 240v) to 380v, which is the main voltage between phases. But I can't discover how to change this (parameter 1 is not operative yet).
I think all the problems in this forum is for that... If somebody discover how to change, please comment how do it. pleeeeeeease....

@rascadecanya

The HEM G2 uses autodetection for Voltage, so parameter 1 does not exist anymore. One thing to note, you need to know what electrical power is running through your home. (Is it 3 phase 3 wire, 3 phase 4 wire, 1 phase, or 2 phase?)

You need to have the correct HEM version to get accurate readings.

I have also heard that parameter 101 needs to be set to either one of these values to 0x00 (0), 0x3F (63), 0x03 (3) while parameter 102 or 103 can be set to report the other clamps to get correct readings if you have an issue with incorrect readings. Can anyone confirm?

Hello,

I have a Home Energy Meter G2 (2nd edition, version info : 3,3,67,1,5) with 3 clamps at home.

I live in France (230V), I have 1 phase power incoming only and I want to measure distincly the electric consumption on 3 separate phases to see the consumption of 3 different devices (for example : lamp, oven, boiler).
HEM is well recognized by Vera Lite and I see 3 different electric consumptions in Vera coming from 3 different devices. But the value is incorrect : I notice that the measured value is around 5 times lower than real value...

Do you have an explanation ? May be there are some specific parameters relative to my configuration to define ? (230V, 1 phase incoming, 3 different devices to be monitored by the 3 clamps)

Please help because I am lost !

Hi,
I live in Italy and I have a 3 phase 3 wire. I had the same problems.
Specific configuration on parameter 101 return errors. I have found a stable configuration to read Watts every 60s and KWH every 4 minutes with this settings: 101 - 16131, 102 - 1794, 103 - 0, and 111 - 240, 112 - 30.
With this configuration I have no more spikes on KWH readings due to voltage readings.
The problems on Watts measure remain. I still have a reading 3 times (I suppose) less then real.
I've try to ask to Aeon support but their answer is that G2 use autodetection for Voltage.
At the moment the only workaround I have found is to use Power Arithmetic plugin.

But if someone have the right solution...

I have installed these on a customers site and generally works okay. Phase 1, Phase 2 and Phase 3 are updating as expected in the Vera but the primary node does not (i.e. the Watts have been the same for 2 weeks).  The root cause of this is because I have some weak z-wave links between the Vera and energy meter as shown by the polls don't work and I get the 'Unable to get any information on node'. I am wondering whether there are any tricks I can do to make the primary node to start updating correctly?  Going on site is a bit of an issue as it is 150KM away

Hi all,

I am just starting to going through this hassle with my new Home Energy Monitor G2.

I have switched device_file for D_PowerMeter1.xml (which automatically changes device_type to urn:schemas-micasaverde-com:device:PowerMeter:1 on the next re-start.

I have a single clamp version for single phase supply, for EU.

Can anyone provide other parameter settings for a single clamp EU version? 

Cheers!

How do you reset the KWH reading? I'm about to take my meter reading to send into the utility company and would like to reset right after.

Edit: found the answer at http://forum.micasaverde.com/index.php?topic=10753.0  I should've searched first.

3 people have been asking if they can use a 3 clamp HEM G2 to measure 3 different power sources like lamps etc and also 3 different live lines. It does not work like that. I have a 3 phase HEM and tried to use it as a 1 phase  meter in the UK (230V) single phase. I was getting incorrect readings from my meter when using one of clamps in the fuse box that has the live wire going in to the house.

I asked Aeon about using the 3 phase meter as a 1 phase meter and this is the response i got.

------------------------------------------------------
Hi evoke,

I believe you have bought the wrong product, if you are trying to install a 1 phase device, you will need to look for the HEM G2 1 phase.

The current HEM G2 you have is a 3 phase 4 wire which you should be able to confirm on the back of the HEM G2 you currently have.

Having the wrong version will give you wrong readings on the total kwh readings as there are different calculations.

The kwh, watt, voltage, and amp are all read from the clamps and calculated in the HEM.

Let me know if you have any further questions.

Cheers,
Chris

Message Body:
Hello Aeotec,
I bought a Z-Wave Home Energy Meter Edition 2 with 3 phase from you. I wanted to use it in single phase mode in the EU. I looked at the instruction manuals on how to do that.
In the diagram in the manual for using the meter in 1 phase it looks like the lead 1 is used to power the meter. From messing around i found out that lead 3 is used to power the meter. Was this the correct lead? If i use lead 3 does that mean i have to use clamp 3 as well to get a proper reading in 1 phase? or do i use clamp 1 for 1 phase?
Are KwH,watt ,amps and voltage all read from the clamps or is amps and voltage read from the extra leads that are not clamps? Like the power supply lead which only has 2 wires.
Regards
evoke

I have two Aeon HEM Gen2 units; one for my solar, and one for the grid.  My problem is that these units only report positive numbers (in Watts).  There are times when I feed power into the grid, and times when I pull power from the grid.  Discerning this from the solar Aeon HEM Gen2 (positive output only) and the grid Aeon HEM Gen2 (which can be positive or negative) is probably not a very sound approach.  I was hoping the Aeon HEM Gen2 units would report positive and negative numbers, but no...

OK, what to do?  I can leave the solar HEM alone (supplying power only), move the grid HEM over to the HOUSE power (drawing power only), and purchase a THIRD unit that can read both positive and negative flow for the grid.  Any suggestions on a reliable Zwave unit that can do this?

Hi, I'am struggling with Aeon HEM G2 (3Phase-4Wire EU version). Watts seems to be correct, but kWh reading is about three times bigger than "real" consumption. Any ideas what could be wrong?

I've tried every possible combinations to parameter 101 - 103, but nothing is working. Clamps 1 - 3 are reporting fine watts, but kWh reading is about three times bigger (C1+C2+C3 = HEM total kWh). I am getting bit frustrated with this piece.. :(

Post by: hmspain on March 31, 2015, 08:17:00 am
I'm not sure if this will help you; I suspect you want to match your HEM reading with your energy meter read by the power company.

I found that resetting the KWH daily helped make sense of the numbers.  I don't really trust the algorithm used by the HEM to calculate KWHrs (my reading leads me to think it does some assumptions); I do trust the watts however since I can measure the watts at my solar panels, and it matches up nicely with the HEM readings.

At any rate, here is the LUUP to zero out the KWHrs every day. I run this scene every night (change the device ID, and you will have THREE not TWO devices):

local meterID = 570
local kwh = luup.variable_get("urn:micasaverde-com:serviceId:EnergyMetering1", "KWH", meterID)

luup.call_action("urn:micasaverde-com:serviceId:EnergyMetering1", "ResetKWH", {}, meterID)

local meterID = 573
local kwh = luup.variable_get("urn:micasaverde-com:serviceId:EnergyMetering1", "KWH", meterID)

luup.call_action("urn:micasaverde-com:serviceId:EnergyMetering1", "ResetKWH", {}, meterID)

Thanks hmspain for advice, but this is not exactly what I am looking for. If I reset kWh counter once in a minute, I will get accurate readings (0 kWh) :P  :D

I think something is wrong somewhere, I am not buying that this device cannot do better accuracy than 300% error. kWh readings are really about three times bigger than real consumption.

Real daily: 72 kWh
HEM: 214 kWh

Watts seems to be correct (for clamps 1-3 and total HEM), for example total HEM wattage is between 1-2 kW for an hour (logging It in datamine) and total kWh reading for that same hour is between 4 - 6 kWh.

Well, I have sent support request to AEON Labs. We'll see if they figure out something that I didn't

It's frustrating, but you can just ignore the KWHr number; I suspect it's a rough calculation anyway, and calculate your own number.

If you have the Wattage (dataMine is an excellent add-on) by hour, you just total things up, and should come to a respectable number.

Below reply from AEON Labs tech support:
Unfortunately, this happens to be an issue with V1.7 in the HEM G2 3 phase 4 wire. This is apparently fixed in V1.8 firmware of this HEM.

They adviced me to contact vesternet where I bought my apparatus.. Let's see what they answer to my reklamation. In all cases I have to pay my electrician to remove failing device, postal fees to UK and installing replacement device. That all will cost me more than twice as much as HEM itself.

You can check firmware version from settings -> advanced -> versioninfo. My version is 3,3,67,1,7 where last two digits seems to be firmware version.

Problem is still present. Vesternet agreed to pay postal fees for sending this unit back, but nobody is willing to pay electrician to remove and install new device which will cost me 150?. If AEON or vesternet are willing to send me a new version and electrian can remove and install device at same time, I can live with this conclusion, but seems to be bit quiet from their behalf.

Now I am monitoring for volts and watts.. kWh reading is unusable.

I have connected a load and measured the amps to 7,38 A and watt shown in Vera was 808w that gives 110v.
So the bug seems to be they uses a static voltage.
