Hello, I’m just getting in to using Vera. I have Vera lite, and am using a zwave thermostat to turn on a propane heater to get the vacation house ready before we get there. The problem is the heater isn’t big enough and I’d like to activat an electric wall heater as well when the status of my thermostat is “heating”. Is there a easy way to do this? I figured a trigger would be the easiest way to do this but I don’t see a way to set values as a trigger? I downloaded the logic app but I really am having a hard time understanding how it works…any help would be appreciated!

There is probably no event defined for when your thermostat changes its “ModeState” variable to “Heating” (or to the other ModeState values). There is also probably no good reason that this is unavailable, except for that it’s simply not present in your thermostat plugin’s .json file. All that being said, would it be sufficient to trigger on the thermostat’s ModeStatus (HeatOn, for example) and when the current temperature is below a certain point? You will get a result that is very close to actually tracking ModeState I think.
Suggestion… What if you just put a 24 VAC relay in parallel with the C & RH terminals. When the stat calls for heat it will activate your relay as well. Just wire the N/O contacts to the line feed for your secondary electric heater.
I think I’ll do just that… might be the easiest thing to do. Another question would be how to hook it up to the 2nd stage of heating? Would that be W2? Otherwise I’ll just tie it in to the 24vac output and kick on my 240v wall heater… done!
Thanks!
