I don't think this is totally related to this issue, but I upgraded to Ecobee PG3 several months ago, use Auto all the time, and had subsequently set up programs to adjust the cool set point down as the temperature from OpenweatherMap went up. This worked fine in the beginning, but then it stopped working. If I make the adjustment to the temperature on the GUI of the thermostat, the change sticks until the next scheduled change in the program schedule. The failure point behavior for my program is that the set point would  change, but then within a minute, it would revert back to the auto temperature setting. In case there is a problem with the program logic, here is an example.

Thanks.

Clarification

I was just about to do something similar. Rather than buy the pricey Ecobee temp sensors, I want to use the various Zwave temp sensors I have around the house. Is changing the setpoint the way to handle a temporary change to accommodate a too cold/too warm part of the house? I just have a single zone and thermostat but want to be able to temporarily warm/cool my living room which tends to be much cooler than the area where the thermostat is.
