Two stage thermostat status


#1

I see in previous API versions, it may have been possible to read the status of what “stage” the thermostat was using, in either heating or cooling mode. Can these keys be added back in?

My particular application is trying to compare energy usage of the HVAC under different staging conditions.


#2

I just got the nest a week or two ago. Over the last two days I’ve been digging into the API and I’m now able to see all my data much more clearly (using highcharts!). I have also noticed that there doesn’t appear to be a way to get the status of second stage heating/cooling. As 7470006 stated, I would also like this ability. In fact, I propose:

hvac_state currently displays:

  • off
  • heating
  • cooling

hvac_state should display:

  • off
  • heating
  • heating 2nd stage
  • heating 3rd stage
  • cooling
  • cooling 2nd stage
  • error

That way everyone could continue to use the same API with additional resolution to the increased demand states as well as error states. I’ve noticed that when there is an error in my system (say E74: No power to Rh wire) the hvac_state is “off” which isn’t very accurate to say…
