Still wanted to report that when Nest is in the status "AutoChangeOver", the device is not reporting watts correctly.

In my case, Cooling + AutoChangeover = FanOnly watts.  Instead, it should be the cooling watts (middle parameter).

I suspect, but do not know, that this would happen with any thermostat that supports AutoChangeOver mode (meaning, I suspect a bug in Vera code because it doesn't know if heating or cooling watts are being used in AutoChangeOver mode, but it could if the code looked at the ModeState variable).  This is all a guess without knowing anything about what Vera code does with UserSuppliedWatts.  In a perfect world, you would open a bug report with Vera, they would look at their code, the would find and fix any bugs they found, and supply us all with that fix. I don't know how different our world is from that one.

EDIT: To be clearer, the Nest plugin does not do anything at all with the UserSuppliedWatts variable, so any use of it is external to the plugin, and it's completely unknown to me what code uses it or how.

Makes sense sir.

I'll open a case with Vera.  Maybe we'll see it fixed in UI88

Ok, MCV was no help...but I did figure out why the Thermostat would not show the wattage correctly. Your limited to 3 digits.

This did not work:
0,1000,0

and this did work:
0,999,0
