Same except I don't bother blocking it from the internet in case I want to use their app instead of home assistant. Haven't noticed any issues doing it this way. AFAIK there are no fees or anything associated with it and I can't imagine my thermostat temperature data is making them any money.
It also knows when you're home based on the occupancy sensors. I'm also not worried with their data collection so, mine is also not blocked from internet access.
