Hi

I previously read this complete thread, but do not recall if the following has been answered:  Will a non-ethernet GEN along with an Dash box (ethernet enabled) work properly/well with Vera script/plugin for GEM, or should I use a ethernet enabled GEM without a Dash?  Because the Dash is $260 and the ethernet add-on for the GEM is $100,I am inclined to spend the extra $160 to have the additional capabilities of the Dash (including its ability to communicate with an ISY.

Specifically, will the Vera be able to respond to energy events/triggers from the GEM/Dash, i.e. will the energy data show up in Vera?

Thanks

  • Release compat is not a bolted-on afterthought
The GEM has two Communications ports.  The DashBox will connect to one of them, and the other will be "spare". 

Depending upon how you have this "spare" exposed (Cabled-serial, Ethernet, WiFi, etc) you'd need to have your Vera connected to the GEM in the same manner.

The Brultech Plugin and the DashBox, cannot both connect to the same Communications port (the Brultech Plugin maintains a persistent Serial|TCP connection to the GEM)

Not sure if that answers your question or not, but it was a little hard to tell how you have stuff wired up.


NOTE: I've stopped running the Brultech Plugin, since it can stretch the resources of your Vera... depending upon how many other things you have running, and how frequently you have the GEM setup to send it's 32 Channels of data (default: 5s).  For SEG Data, I have a separate RaspberryPi, running btmon.py, that's periodically polling the GEM, and pushing the data to SEG.

Thanks once again Guessed.  You are ever helpful!!

I am going to copy your reply to the folks at Brultech so they can help me finalize my config (not bought yet).

Because I do not yet know what final energy monitoring config I will be most satisfied with, I am trying to keep my options open.  I know ISY with Dash works ok and it seems Vera with ethernet GEM works ok.  I just want to confirm with Brultech that non-ethernet GEM with ethernet dash can also work well with vera.

Thanks again!

I am not certain that vera can get data from the dashbox instead of direct from the GEM.

Just playing with this myself after setting up a new GEM 10 days or so ago (ethernet GEM, no dashbox thus far). At the moment I'm also pulling data from the GEM using btmon, and sending it both to SEG and to a local installation of emoncms. Because btmon is talking to the GEM over ethernet, I'm not currently getting any data feed into vera. emoncms is quite fascinating as a local facility and was pretty easy to get running, but I realize that so far I have little idea what I'm doing with setting up its data feeds, beyond the basics of daily kWh, etc. Dashbox seems quite attractive as a turnkey solution. Although I was able to resurrect a long-defunct Nokia Internet Tablet (N800) as a handy current-power-use monitor.

It may be possible (with wholly new code), but the current Plugin is only designed to talk directly to either a GEM or ECM-1240's, via their specialized interface.

Yup, it's why I now ship all this data to SEG.  I really wasn't using it in Vera for anything automation-centric, so I figured I'd lighten the load on Vera. 

I will revive that feed in openHAB at some point, since the HW is far more capable, and my long-term automation plans now include real-world usage for that data (mostly because I added Solar to the mix).

When I get to that, I'll probably enable MySQL in btmon, and have it do the work to push/keep the data locally so openHAB can work with a local DS.

It would be a question for brultech, but I wonder how feasible it would be for dashbox to present a "virtual gem" interface, for other systems to retrieve data from. Not only to get data into vera, but could also be used for btmon, etc.

Well at least my vera lite didn't actually keel over during the couple of days I had it fetch GEM data! I'd been plotting data in datamine from my earlier Aeon HEM experiment, but there didn't seem much point in doing that once I started sending the data to SEG or emoncms for storage. But still, it would be handy to get the data into vera somehow, there are probably some useful automation-type things to do with it (for those of us who aren't yet ready to jump to openhab).

I've split out the whole discussion on the cutover to using the SmartEnergyGroups.com (SEG) Service to Monitor Energy usage.

That part is now here, so it's easier to find:

Hi

Im just letting you know I added a very detailed Step-by-Step guide to implementing your Vera/SEG script in the new forked thread you created.  This exact post is here:

Thanks @Guessed!!!
