Aqara SSM-U02 Single Switch Module T1 (SSM-U02)

It is a Zigbee 3.0 relay module designed to control lamps or devices without needing a neutral wire in the electrical box.

Allows remote control via the Aqara Home or Apple Home application, supporting functions like time control and smart home automation.

Features overload and overheating protection, automatically cutting off power if the load exceeds the safe limit (max 5A / 1250W).

Compact size (42.9 × 40 × 21.4 mm) allows it to fit easily into almost any wall box behind existing wall switches.

Can be combined with other Aqara smart devices to create various smart scenes and automate traditional lights.
