Wyze Termostat compatibility

I’ve read a few forum posts and have a question about the Wyze Thermostat. I saw mentioned on another post that a user’s furnace will lose its variable speed function when using the Wyze Thermostat. Is this true of all furnaces? Or is this on a case by case basis?

I just bought a new HVAC system earlier this year and chose the variable speed specifically for my needs lol don’t want to lose it



That was for that specific user’s setup. Yours may differ. What is your current setup?
