Eve Thermo

Quick verdict

The Eve Thermo is the TRV for people who refuse to let a cloud service control their heating. Thread and Matter keep everything local, and Eve's privacy record is strong. It fits standard European radiator valves and works well in Home Assistant for per-room temperature control. Premium priced, but you are paying for real local independence.

Standout: Privacy-first smart radiator valve with Thread and Matter for fully local heating control.
