(SOLVED) ZHA connection failed with SONOFF Zigbee 3.0 Dongle

Configuration
21

Hi everyone, I have also a problem like this one;
I’m running HA in Docker, so, MQTT and zigbee2mqtt and separate containers.
My dongle appear in HA integrations but when I try to adopt him (Do you want to set up SONOFF Zigbee 3.0 USB Dongle Plus V2?) it return the error: Failed to probe the usb device

Any ideias? Thanks

Hey I seemed to have sort of the same issue but for me the problem was caused by the Silicon Labs Multiprotocol running, while it didnt show that it was running at first it kept trying to connect to the sonoff adapter (this was visable when looking at the logs), after waiting a bit and refreshing the page (ctrl, f5) it did show up as running and then I could stop it. This is what fixed the issue for me. Would be nice to have some sort of warning in the UI that tells you something else is running please first stop that instead of just “failed to setup” when trying to reload. Hope this might help someone and have a nice day!

I’ve tried everything here and still cannot get ZHA to connect to my dongle.

I’m running Home Assistant (snap install) on Ubuntu and I have the Zigbee 3.0 Dongle E. This machine is a low powered micro pc that hosts a nextcloud instance.

I updated the firmware on the dongle, changed permissions to /dev/ttyACM0, added my user to crucial groups and nothing has solved the issue. I also tried adding a usb extension and removing the antenna but that also had no impact either.

Is there another dongle worth buying or is there some other explanation for why this doesn’t work? I’m a novice, just getting into HA and so far finding this extremely frustrating.

same here still not works

I restoded frpm an old backup and then update it again and it works but I have problem to install the ewelink addons

My solution seems to be that ZHA and Zigbee2MQTT cannot run at the same time.
I had running Zigbee2MQTT (in docker) and tried to add also ZHA. That didn’t work and gave me the errors.
After stopping Zigbee2MQTT container I could add ZHA successfully.

I’m not sure which I’m going to use later on.
Zigbee2MQTT did not pickup battery of added button device. ZHA did.

Not working is expected. ZHA and Z2M would both be competing to talk to the same sonoff USB dongle, and both would want exclusivity…

28

After learning this I did find indeed texts that say you can’t have both running. I bought the Sonoff USB and as a beginner thought to install both to look which was best for my needs. Hope I made the right choice with ZHA and disable Z2M.
More off-topic: I’m not satisfied with the range of controller. 7meters is apparently to far.

Thank you for the tip, I now can run one or the other I will stick with zigbee2mqtt, zha isn`t displaying all the properties on my devices.
thanks again.

Thats exactly my problem. I installed a homeassitant image on my pi5. unfortunatley i have no access to systemctl (/etc/systemd/system/). i just have the hass web terminal. how can i change the permissions for the usb ports?

Thanks in advance!

Even I faced the same problem. I have setup Home Assistant in Raspberry Pi4. After plugging in the Sonoff USB 3.0 Plus, Home Assistant discovered automatically but while Adding I’m getting error. I tried to configure manually but every time I’m getting “Failure to disconnect” error. After restarting the Home Assistant, it automatically added.

Thanks for the tip: uninstalling the deConz add-on (and restarting) did the trick for me.
