Compatibility notes
- SONOFF's NSPanel Pro firmware adds a Matter bridge that syncs Zigbee sub-devices to Apple Home, Google Home and Alexa with one pairing (sonoff.tech news, read 2026-10-18).
- SONOFF's supported-devices list names SNZB-04P with 'Opened/Closed' under the Matter Bridge feature (sonoff.tech, read 2026-10-18).
- Zigbee 3.0 sensor with CR2477 battery; no native Matter or HomeKit, so it relies entirely on the bridge (sonoff.tech, read 2026-10-18).
