Choose countryThe Sonoff SNZB-01M is a wireless controller with 4 independent keys for lights, blinds, thermostats, sockets and smart home scenes. It supports up to 16 control actions in Zigbee mode, with available functions depending on the platform.
Controls and connections
- Press actions: single, double, triple and hold. Triple press is not supported in eWeLink-Remote mode.
- Two protocols: Zigbee operation requires a Zigbee hub; eWeLink-Remote requires a compatible gateway.
- TouchLink: pair a compatible bulb directly without an app by bringing the button within 10 cm and holding the relevant key. Check the bulb's specifications for support before purchasing.
- Direct bindings: Zigbee2MQTT and Home Assistant via Zigbee2MQTT support binding to compatible Zigbee devices for direct control without an internet connection.
Platforms and mounting
The button works with eWeLink, Smartthings, Home Assistant and Zigbee2MQTT. Alexa connectivity uses account synchronisation in the eWeLink app and supports basic actions only. OTA updates, battery level display and binding options vary by platform.
Attach the magnetic base to a smooth surface with VHB tape or screw it to an 86-Type or European round Φ60 mm flush-mounted box. The button detaches from the base for relocation or battery replacement. It can also be used with 3D-printed parts.
The CR2477 battery provides up to 4 years of operation in Zigbee mode. The package includes the button, magnetic base and user manual.
