  • Zigbee or Zwave temperature/humidity sensors are common. Add a 3-circuit relay box and you can simulate the behavior of pretty much any thermostat with a few rules.

    HA or any other system that can toggle outputs based on sensor thresholds would work just fine.

    there are some subtleties with real HVAC thermostats, like running your AC compressor at least five minutes and ensuring that it stays off for at least 5 minutes when it’s turned off.

    Performance is the major flaw with microkernels that have prevented the half-dozen or more serious attempts at this to succeed.

    Incurring context switching for low-level operations is just too slow.

    An alternative might be a safe/provable language for kernel and drivers where the compiler can guarantee properties of kernel modules instead of requiring hardware guarantees, and it ends up in one address space/protection boundary. But then the compiler (and its output) becomes a trusted component.
