Sonoff Zigbee dongle test

Configuration

Hello,

I bought the recommended USB dongle.

At Domadoo: SONOFF - USB Zigbee 3.0 Dongle + External Antenna (V2) ZBDONGLE-E compatible with Home Assistant and Zigbee2mqtt

I can see the USB port where it is located

moi@mamachine:~$ lsusb -d 10c4:ea60 -v

Bus 005 Device 006: ID 10c4:ea60 Silicon Labs CP210x UART Bridge

The installation goes well at least at the beginning then boom!

Apparently everything is « started »

But there is this message:

Zigbee2MQTT container error: h[2026-10-01 19:01:02] error: z2m: Error: Error: I/O error setting custom baud rate of 115200

Is this a speed (baud rate) issue?

Of course I restarted the server hosting Gladys several times.

Thanks in advance…

Hello. You need to choose the ZBdongle-E dongle (you chose the P in the list).

In Configuration > Dongle

Thanks for the suggestion.

The error message is no longer the same.

Zigbee2MQTT container error: G[2026-10-01 20:39:32] error: z2m: Error: Failure to connect

Strangely, the proposed devices are changing…
