⚙️ Motor Control Module with Zigbee2MQTT
Nous B4Z is a Zigbee 3.0 module designed to control motors in blinds, roller shutters, and gates. Thanks to this module, which is placed behind the switch, you can control standard motors and add their operation to the TUYA/Smart Life app, and thanks to Zigbee2MQTT support, also to Home Assistant and other automation platforms.
The module features switch inputs, meaning classic control of the connected shutter is always available. Thanks to its small dimensions, it easily fits into a standard 6cm junction box.
