When used together with Sonoff Zigbee Bridge or SmartWise Zigbee Bridge Pro, it can also trigger WiFi-based Sonoff / other eWeLink devices via eWeLink cloud based on the detected smoke.
Zigbee supports the mesh network topology, so the Zigbee range can be extended by plug-in other Zigbee devices, such as Sonoff Zigbee Mini or SmartWise Zigbee relays or Zigbee wall switches, acting as a Zigbee router.
