Is anyone aware of a smart TRV which can, via homeassist, control a combi boiler that is wired to an OTGW?
It looks like tado valves with the internet bridge, bit without a local extension unit or thermostat, /might/ do this…
I am interesting same thing. I have TRV in every room and i want to use 1 room temp value like room thermostat and opentherm boiler control.
