Product description: Aqara T1 SSM-U01 - single-channel in-wall relay with neutral wire - ZigBee
The Aqara T1 SSM-U01 allows you to add Smart Home functionality to a traditional switch or socket without changing its appearance. The module is mounted in a junction box and connected to the neutral wire . It allows you to remotely turn the circuit on and off, create schedules, and automate it with other Aqara devices, such as motion or door sensors . Built-in energy measurement allows you to monitor the connected device's consumption. The relay supports ZigBee 3.0, a memory function after a power outage, and overheating and overload protection. Its compact dimensions of 42.9 x 40 x 19.9 mm facilitate installation behind an existing switch or socket.

The Aqara T1 can be used to automate traditional lighting, a ceiling fan, an electrical outlet, or any other compatible receiver.
Main features of the Aqara SSM-U01 module
- ZigBee 3.0 : wireless communication that allows the module to be included in the Aqara smart home ecosystem
- Single-channel control : the module allows the control of one electrical circuit
- Supports up to 2500W : Maximum resistive load allows you to control lighting and many electrical devices
- Energy consumption measurement : the ability to monitor energy consumption and analyze data regarding the operation of the connected device
- Remote control : ability to check the status and control the device from the Aqara system
- Schedules and automations : the ability to automatically turn on devices at specific times or based on signals from other Smart Home components
- Power outage memory : ability to configure device behavior after power is restored
- Two-way switch support : can be integrated with existing installations using a 2-way system
- Overheating and overload protection : additional protection during module operation
- Compact design : housing dimensions of 42.9 x 40 x 19.9 mm facilitates installation in a box behind a switch or socket
- Version with neutral wire : the module requires a neutral wire connection
- Works with the Aqara gateway : a compatible ZigBee 3.0 hub is required to use the smart function
Stable ZigBee 3.0 communication in the Smart Home system
The Aqara SSM-U01 uses the ZigBee 3.0 protocol based on the IEEE 802.15.4 standard, allowing it to communicate with a compatible gateway and other home automation system components. Transmission occurs in the 2.4 GHz band, and the manufacturer's declared effective communication range is up to 30 m indoors - the actual range depends on, among other things, the building's construction and the presence of interference sources. The module does not communicate directly via Wi-Fi, so remote control and automation are required. A compatible ZigBee 3.0 gateway is required. Connecting to the Aqara central unit allows you to integrate the relay with sensors, switches, and other devices, creating extensive smart home scenarios.

The small size allows you to retain the existing installation elements while expanding them with Smart Home functions.
