Call HVAC fan on stdev of Ecobee3 temp sensors

temperature
variables
#1

1) Give a description of the problem
Its more efficient to run the HVAC fan to equalize temps throughout the house (even without firing the gas furnace), so I am trying to make that happen intelligently.

2) What is the expected behavior?
When the temp imbalance is too large the HVAC fan will run for 10 minutes then go back to auto - only run with a call for heat from the Ecobee.
I have set the Ecobee “minimum fan run time per hour in Auto” to 0 mins in the Ecobee GUI, so the fan should only run with Ecobee calls for heat or when Webcore triggers it.

3) What is happening/not happening?
Nothing.
I can watch the @EcoTempVar climb over the setpoint, but the HVAC fan will not come on.

**4) Post a Green Snapshot of the piston!

Also, to confirm - Webcore calling the fan to on / auto shouldn’t conflict with Ecobee3 doings it’s job in regards to heating, right? :crossed_fingers:

I think line 18 in your “8qwes” piston should be a trigger instead of a condition.

Such as:
IF {@EcoTempVar} rises above 1.0

I’m not sure that I understand what you mean. I did input that as an “If Block” in the piston…?

#5

If you click on line 18 to edit it
temp
there should be a drop down list where it currently says “is greater than”.

My advice was to change that to a trigger such as “rises above”

Oh I see now, thank you. I have updated it and will monitor.
