Looking for a 2-wire wifi thermostat for radiant in-floor heating system that can integrate with HA for US market. Thanks
I believe the Gen 3 Nest does not, in most cases, require a common.
Not sure if that’s what you mean by 2-wire, but Sinopé has a great line of line-voltage thermostats, including some made for in-floor heating: Store | Sinope Technologies US (and they only have 2 wires in the back)
Wifi models integrate through a module available on HACS, and Zigbee models integrate directly with HA through ZHA.
Thanks for your reply, I never realized replacing the thermostat was gonna be so difficult…but I’m learning. I guess what I’m looking for is 2-wire low voltage. Line voltage is the standard voltage—120 volts, I have a transformer in the system that drops the voltage to 24 and runs 2 wires to the current thermostat. No cooling.
@ServiceXp I will look at the nest, thanks
