What You'll Need

Step-by-Step Setup

Check radiator compatibility: Eve Thermo fits most radiator valves with M30x1.5mm threading. Use included adapters for other sizes (RA, RAV, RAVL).
Remove old valve: Turn off the radiator. Unscrew the existing thermostatic valve head by rotating counter-clockwise.
Install adapter if needed: If your valve isn't M30x1.5mm, attach the appropriate adapter from the included set.
Attach Eve Thermo: Screw the Eve Thermo onto the valve clockwise until hand-tight. Don't over-tighten.
Insert batteries: Remove the back cover and insert 2 AA batteries.
Calibration begins: The device will automatically calibrate to your valve's range. Wait for "CAL" to finish.
Open your Matter controller app: (Apple Home, Google Home, etc.)
Add Matter device: Scan the QR code on the Eve Thermo or its packaging.
Assign room: Place the thermostat in the appropriate room in your smart home.
Set schedules: Configure heating schedules and temperature presets.

Calibration fails: Ensure the valve pin moves freely. Remove and reattach Eve Thermo. Check that batteries have sufficient charge.
Won't connect to Matter: Ensure your Thread border router is online. Move closer during pairing. Check that Matter is enabled in your controller.
Temperature inaccurate: The sensor is in the device—radiator heat can affect readings. Offset temperature in settings if needed.
Valve leaking: Check adapter is correct size and properly seated. Ensure O-ring is in place. Tighten connection.
Motor grinding: Recalibrate by removing and reinserting batteries. Check for obstructions on the valve pin.
