So I am in maybe a bit of a niche here.
I am in the process of changing out my 15-year-old Heating/AC setup. I would like to get a more efficient/quiet combo. 2-Stage Heat, 2-Stage Cool, Variable Speed Blower, and Humidifier (I am in Canada, 5 months on heat means inside is always dry af).
Currently, I have an Ecobee 4 which works pretty well with Home Assistant through the Homekit integration (much more stable than the actual Ecobee integration).
Unfortunately from what I understand, with a Variable Speed Blower, I need a communicating thermostat that is vendor proprietary and doesn’t have an open API in most cases, thus no integration with Home Assistant (at least that’s the case for Lennox iComfort).
I am not loyal to Lennox, but can’t find any third-party thermostat that supports Variable Speed Blower.
If you know of any thermostat that supports a variable-speed blower that also has integration to Home Assistant, please let me know. I also have no problem buy furnaces from another brand if their thermostat has an integration.
Basically, If it works with Home Assistant, I will get it.
