Description
The Aqara Single Switch Module T1 (No Neutral) is a single-channel relay module designed to convert a traditional light switch or outlet into a smart device—without needing a neutral wire. This makes it especially suitable for older homes or installations where a neutral wire is not present. Aqara+1
Once connected behind your existing switch or outlet box, the module pairs with a Zigbee 3.0 hub (such as an Aqara Hub) to enable app control, scheduling, voice-assistant integration (e.g., Apple HomeKit, Amazon Alexa, Google Assistant), and device-scene automation. Aqara+1
Its compact dimensions allow it to fit into standard European wall-boxes, helping you keep your original switch aesthetic while seamlessly adding smart functionality. Aqara UK Shop+1
In summary, this module offers a discreet, powerful way to modernise existing wiring setups and bring smart-control capability to lights, sockets or other circuits—even in installations where a classic neutral feed is absent.
