Especially with the rising cancer known as SaaS. Soon you'll need to be paying $10/mo for your thermostat to work, and you'll need to fork over another $200 every other year to upgrade the hardware.
Sounds like too much to ask?

I don't need the company to be bankrolling a $2mm/yr AI team so that the thermostat can try to make better guess about when I want to turn on the heat.
