Sonoff Dongle M Zigbee Coordinator

The Sonoff Dongle M is a Zigbee coordinator: the radio your Zigbee devices, such as leak sensors, vibration sensors and scene buttons, talk to. Sensa needs one before it can use any Zigbee device.

How it connects​

The Dongle M sits on your van's network with its own address, by Ethernet or power over Ethernet. Sensa finds it by looking across your network for it.

Add to Sensa Nomad​

The Dongle M must be in Zigbee Coordinator mode, which you set on its own web page. Sensa cannot find it in any other mode.

Then open Settings, choose the Devices tab, tick it under Discovered and press Add Selected Devices. If it is not there yet, press Scan. If it is on a different part of your network, change the Subnet next to the Scan button first.

Sensa then sets up Zigbee to use the coordinator for you.

See Adding devices for more.

What you see​

Once the coordinator is added, press Pair Zigbee on the Devices tab, then the pair button on your Zigbee device, and the device is added to Sensa on its own.

The Dongle M has no readings of its own in Sensa. Its status and firmware are on its own web page.

Good to know​

  • Give it a fixed address on your router, usually called a static lease or DHCP reservation. Its address is stored in the Zigbee settings and is never chased automatically, so a coordinator that moves has to be put back by hand. See Network planning.
  • If every Zigbee device stops answering at once, see Every Zigbee device goes unavailable at once.
