How to use

Place the sensor in the area where you need to monitor temperature and humidity, avoiding direct sunlight, heat sources or very damp locations that could affect readings. Install the device at a typical breathing height for the room or on a stable shelf or wall mount. Pair the sensor with a compatible Shelly hub or controller following the manufacturer pairing procedure, then configure measurement intervals and alert thresholds through the Shelly app or web interface. Once configured, the sensor will transmit periodic readings for logging and automation.

Recommendations

For reliable readings, position the sensor at least 1–2 meters away from heating elements, air vents and windows. Periodically check wireless signal strength and battery or power status if applicable. Use stored measurements to define automation rules that maintain comfortable and energy-efficient indoor conditions.
