Tado Smart Radiator Thermostat shows temperature much higher or lower than the actual room temperature.

Safety first: Radiator may be hot; handle with care.

• Check placement: Ensure the Smart Radiator Thermostat is not covered by curtains or furniture and has free air circulation.
• Compare with room thermometer: Place an independent thermometer at seating height in the room and compare readings.
• Apply offset: In the Tado app, set a temperature offset for the radiator thermostat so that the displayed temperature matches the actual room temperature.
• Consider wireless temperature sensor: If available, use a separate Tado Smart Thermostat or wireless temperature sensor in the room as the primary temperature reference.
