Not sure why this is being downvoted, it's a pervasive flaw across all these IoT products. See my description elsewhere here about how Haier "smart" controls work. It's completely insane, and pointless. For systems that can't fail--I include heating systems in the winter--this kind of "move fast and break shit" way of doing it is malpractice. The last thing in the entire world I want my furnace controls doing is an automatic OTA firmware update. Ever.

Exactly. I want a "smart thermostat" that's entirely under my control, not the manufacturer's.
