How to use

Place the Shelly H&T Gen3 in the room or area where you want to monitor conditions, avoiding direct sunlight and sources of heat or moisture that could skew readings. Install batteries if required and connect the sensor to your local WiFi network using the Shelly mobile app or web interface. After connection, verify that temperature and humidity values appear in the app and configure any desired thresholds for notifications or automation rules. Position the unit at breathing height for typical occupancy areas or near the object you want to protect for targeted monitoring.

Recommendations

For reliable readings, locate the sensor away from HVAC vents, kitchens, bathrooms or windows where transient changes may occur. Regularly check battery status in the app and replace batteries as indicated to maintain continuous reporting. When integrating with automation, set conservative thresholds and add delay or hysteresis to avoid frequent toggling of HVAC equipment.
