I am working on the next version of HVAC Zoning and Ventilation Control. As part of that effort, I would like to provide information about what thermostats are suitable. I have tested a few myself, but I don't have the budget to purchase samples of each type for testing. If you have a thermostat connected to Hubitat (whether by ZWave, Zigbee, Cloud service, etc.), I would appreciate information on its performance. The metrics of particular relevance for this application are:
-
How quickly and reliably are operating state changes (heat call, cooling call, fan call, idle) communicated to Hubitat?
-
How quickly and reliably are temperature changes communicated to Hubitat?
The models I have tested so far are pretty disappointing. They seem to be good about sending information from Hubitat to the thermostat but not very good at sending information the other way.
