Any thoughts on how I can acheive a "seperate" Gasmeter device (besides the 4 seperate existing devices)? Now the gas value is given in the master device. Electric values are also passed through to the four seperate values (day/night/in/out).

Thanks.

After upgading to Vera3 (from Vera2) I cannot read my metervalues anymore...

Failed to open IO Port is the error on top of Vera.

have tried several things...  change IOdevice number (is 102 and tried 101 and 103)... removed the meterkast device and recreated (but now I only have 1 out of 5 previous devices). Values keep empty.

what could be wrong with my settings? the serial port setting is as follows attached.

Databit should be on 8 and not on 7.

Hi mfp, why? P1 is 7 bits. See also first post.

After the device is created you have to configure the serial port. First attach the cable. Go to apps=>develop apps=>serial port configuration and select the correct USB device. Set the serial parameters to 9600,even,7bits,1stop bit
In the dropdown box select the name you used creating your device.

Btw have tried to be sure.... same problem.

You`re right confused the settings with another device, your settings are correct. Can you see anaything in your logfile?

Login with a a client like telnet. On Windows you can use puTTY.

You can find the logfile in var/log/cmh/LuaUPnP.log. With vi you could read the file.

If you are on windows you could also transfer the file to the windows machine and read it over there. To do this you could use the tool WinSCP.

I also tried to achieve this by editing some files but i never got it working (not even close). Would be nice if someone could fix that, or give advice on how to do this.

Also someone know if it is possible to change the code so that the data can be taken from a raspberry pi with ser2net where the p1 cable is connected to?

Would it be possible to use 'Actual usage' (watt) as input for the Datamine plugin's dashboard tab?

The manual reads: "The whole-house gauge provides the current whole house energy use. It is a sum of all the whole house energy categories..."

'Actual usage' collected with the Dutch Smart meter plugin equals the 'whole house energy usage', but the datamine plugin needs to know  that. Possible?

I found already a way to connect the plugin to my raspberry pi. 
The app IPSerial Plugin which can be found in the app store does the trick.

@Xanlle

Read the excellent manual by Chris http://forum.micasaverde.com/index.php/topic,13057.0.html. In it you can read that for whole house you just have to use category 1 and the selected device is put in the category whole house. This works for this device.

Is it possible to see the difference in  kWh of solar power every min in a datamine graph?
This is because my dutchmeter can't show current returned power(Watts).

Today i installed solar panels but...... The smartmeter plugin does not show export actual usage. Is that correct ?

I don't know if it is correct. What i do know is that is exactly the same as in my situation.
When exporting electricity it shows 0 or 10 or -10.

Strange i'd expect a watt number for export too
