Can anyone recommend a thermostat system that is self-hosted (no third-party cloud) and integrates into homeassistant nicely? Something tasmota based would be even better.
This is the final bit of home automation that’s been difficult to solve. I’ve got a heat pump system and there are very few smart thermostat systems that aren’t beholden to a public cloud service.
Oh you needed to replace your ac units got it. 7k seem very reasonable for that. I thought you were talking about some home automation equipment that needed to be replaced. I’m glad you had that in your budget. I personal would not be concerned with breaking anything with thermostat even a DIY one as if you have a “normal” thermostat, aka one that did not come with the air handler, then there are no wires that you can touch together at the thermostat that could cause a problem.
