Perfect addition for smart tado° radiator thermostats - tado° wireless temperature sensor This temperature sensor is the ideal extension for tado° radiator thermostats to control several radiators in one room at the same time. It enables a more precise control of the room temperature according to one's own wishes, because it measures the temperature exactly where it is placed and not only on the radiator itself. For example, the sensor can be placed on the wall, on a table or on a shelf. By linking it to thermostats, the wireless temperature sensor ensures that the radiators are heated up or cooled down, depending on the desired room temperature. Since it is networked with all devices in the room, even large rooms are comprehensively controlled. Technical information / compatibility: - measures temperature and humidity (accurate to 0.01 ° C) - radio connection 868 MHz - power supply 4.5V DC (3 AAA batteries, 1,200mAh) - LED matrix display with one mechanical and two touch buttons - Sco
