SONOFF lists these Zigbee hubs: SONOFF ZBBridge-P, ZBBridge-U, Bridge-M, NSPanel Pro and iHost (eWeLink app); Home Assistant via ZHA or Zigbee2MQTT with a SONOFF ZBDongle-P, ZBDongle-E, Dongle-M, Dongle-PMG24 or Dongle-LMG21; Amazon Echo (Plus 2nd Gen, Echo 4th Gen, Show 2nd Gen); and Aeotec SmartThings Hub (V3).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGood to know:\u003c\/strong\u003e A Zigbee hub is needed for the app, scenes and the extra screen data. Zigbee2MQTT supports it out of the box, but the remote sensor and weather functions need a script; ZHA support is limited until native support is merged. SONOFF's setup notes list iHost support as coming with a later firmware update, so check your gateway firmware first. Keep it within 0–50°C.
