SONOFF SNZB-01M ZigBee smart button

Product detailed description

The Sonoff SNZB-01M is a sleek wireless push button with four independent buttons that offers advanced smart home control options. Using two protocols, Zigbee and eWeLink-Remote, you can control lights, blinds, thermostats, outlets and entire scenes with a single touch. Each of the four buttons supports different types of presses (single, double, triple, and hold) for up to 16 different control actions in total. The TouchLink feature allows direct pairing with smart bulbs without the need for an app, and the magnetic mount makes it easy to place the button anywhere. The CR2477 battery provides up to 4 years of Zigbee operation, eliminating the need for frequent replacement. The compact, minimalist design (Φ50 × 22.5 mm) fits perfectly into modern interiors.

Dual communication protocol
The button operates in Zigbee network mode (requires a Zigbee hub such as ZBBridge-P, ZBBridge-U, NSPanel Pro, iHost, or USB dongle) and in eWeLink-Remote mode (requires an eWeLink-Remote gateway such as M5 Stack, MINIR4, NSPanel, MINI-RBS, and others). This versatility allows you to adapt the device to your existing smart home ecosystem or choose your preferred method of communication. Depending on the chosen platform, various features are available, such as OTA updates, battery status display and pairing options.

TouchLink - instant control of bulbs without apps
TouchLink is a true revolution in ease of use. To pair the button with a smart bulb, simply bring the button to within 10 cm of the bulb and hold down the corresponding button. Once paired, you can control the bulb directly - no need to configure it in the app. This is ideal for the elderly or children, who can easily turn the light on and off with a single press. Note: TouchLink availability depends on the bulb model - check the bulb specifications before purchasing.

Four buttons, sixteen control options
Each of the four buttons responds to four types of presses: single click, double click, triple click and hold. For example, you can configure one button so that a single click turns on the living room light, a double click turns on the lamp to 100%, a triple click starts the "Movie" scene, and a hold turns off all the lights in the house. Such options give you almost unlimited control over the devices and scenes in your smart home.

Link function - direct communication between devices
The link function is a feature that allows you to directly link the button to other Zigbee devices without connecting a gateway or cloud. This means instant response and operation even when there is no internet connection available. The button can directly control switches, light bulbs or other compatible Zigbee devices. The Bindings feature is available in the Zigbee2MQTT and Home Assistant platforms (via Zigbee2MQTT).

Smart scenes at your fingertips
Create personalised scenes tailored to your lifestyle. With a single click, you can activate a "Leaving Home" scene that turns off all the lights, closes the blinds and sets off the alarm. With a long hold, you can activate the "Home Cinema" scene, which dims the lights, closes the curtains and turns on the TV. You can also press the button to set up push notifications on your smartphone, such as food preparation alerts or approaching bedtime.

Magnetic holder and flexible installation
It comes with a magnetic base that can be mounted in two ways - using VHB tape on smooth surfaces or screwed onto standard flush mount boxes (86-Type or European round Φ60 mm). The round button magnetically attaches to the base and can be easily removed if you want to move it to another location or change the battery. In addition, the button can be used with 3D printed parts, allowing for creative applications such as a night light or a floor switch.

Wide compatibility with smart home platforms
The SNZB-01M works with eWeLink, Smartthings, Home Assistant (via ZHA or Zigbee2MQTT), Zigbee2MQTT, and Alexa (account-based synchronization in the eWeLink app). Each platform offers a slightly different range of functionality - for example, triple-clicking is not supported in eWeLink-Remote mode and Alexa only supports basic actions. Fans of open source solutions will appreciate the full integration with Zigbee2MQTT and Home Assistant, which enables advanced automation without the use of the cloud.
