The Sonoff SNZB-01P is a compact Zigbee 3.0 wireless scene switch with a CR2477 coin cell (up to five-year life) and a magnetic/adhesive mount. It’s a reliable, local-only Zigbee button for Home Assistant or Zigbee2MQTT setups, best as a single-action scene trigger rather than a multi-button controller.
Buy if you want a cheap, local Zigbee 3.0 button for Home Assistant; avoid if you need multi-button control or easy local battery sourcing.
