Tech Level Indicator

🟡 INTERMEDIATE: Requires a ZigBee hub or bridge to function. Download the eWeLink app or configure through Home Assistant, pair the sensor using the reset button, and set up your automation rules. Basic smart home knowledge helpful but full instructions provided.

Pro Tip

Position the sensor in a corner at about 2-2.5 metres height for optimal coverage. The 120° detection angle works best when mounted high, allowing it to "look down" at the area you want to monitor rather than straight across at head level.
