The compact sensor measures temperatures between minus 20 °C and plus 55 °C, as well as relative humidity from 0 to 99%. When used in conjunction with other Homematic IP devices, it offers numerous practical applications. For example, the sensor can be used for ventilation or dehumidification controls, as a frost guard for heating sensitive greenhouse plants, and in many other scenarios. Additionally, the collected weather data is displayed and analyzed in the Homematic IP app. The power supply is provided by two LR6 batteries, which can typically power the sensor for five years. The necessary mounting materials are included.
