The Sonoff SNZB-01P is a tiny Zigbee wireless button with CR2477 battery power, multi-press (single/double/long) actions and OTA support — offering low-latency, local (cloud-free) control when paired to a Zigbee coordinator and advertised multi-year battery life. It’s a solid, budget-focused Zigbee scene controller for Home Assistant/Zigbee2MQTT users, but requires a compatible Zigbee hub and careful integration (entity/exposure changes and its sleep behavior can affect automations).
For Home Assistant/Zigbee2MQTT users wanting an inexpensive, local, battery-powered scene button; avoid if you lack a Zigbee hub or want always-listening remote behavior.
