New OH user - trouble binding to Sonoff Zigbee USB 3.0 Dongle Plus

So I’m assuming at this point the zigbee devices I have turned on/powered up should start showing up in the zigbee2mqtt web page, but I’ve never seen any devices after setting the “Permit Join” button.

They won’t just magically appear. You will need to set each of your devices into pair mode - check the zigbee2mqtt documentation for instructions on how to do that for your devices.

It is my understanding that the Sonoff Dongle will “see” the zigbee devices and z2m will connect to the Sonoff Dongle to pull that data to Openhabian through the Ember Coordinator.

I’d be interested to understand where this idea comes from.

This is how it should work:

• Your ZigBee dongle connects to zigbee2mqtt.
• Your ZigBee devices connect via your ZigBee dongle to zigbee2mqtt.
• Zigbee2mqtt connects to your MQTT broker (Mosquitto in your case)
• openHAB also connects to your MQTT broker via the MQTT Binding.
• openHAB and zigbee2mqtt now ‘talk’ to each other via the MQTT broker. openHAB does not interact with your ZigBee dongle at all, as previously mentioned.

So it goes:

ZigBee device → ZigBee dongle → zigbee2mqtt → MQTT broker → openHAB via MQTT binding.
