I bought a Honeywell Z-Wave thermostat because I have a more complicated HVAC setup than the typical American home. It was one of the few I could find that was compliant with a home automation protocol that didn’t require something that announced its existence to the Internet. It’s been solidly reliable, replacing my dead Nest thermostat.
The thermostat:
Not multistage, but it’s a heat pump with auxiliary heat. I have multiple zones controlled by dampers, too, soni have two of these thermostats.
