What I have to do ? I want use it as zigbee but don’t want lost my current network and don’t want reinit all devices

You need to be patient and wait.

It will index the firmware every x amount of hours.

I have two HA Connect ZBT-1, one of them shows the 7.4.4.0 firmware the other still shows ‘Unknown’ and it will eventually recheck and show the correct firmware.

See releases notes of HA 2025.4 .

The stick I’m using with ZHA shows the correct version.

The stick I’m using with Z2M shows unknown as well after 24h.

Will try to reboot the host to see if that changes. I know they are both running 7.4.4.0 as I updated them myself through the Add-On.

There are more people with issues:

It worked for me after updating to HA 2025.4.1 .

For ZHA it will auto disable the radio to update and re-enable it after update is finished.

For Z2M you need to stop Z2M while you update the Zigbee FW, and afterwards you can start Z2M again.

I have the Unknown state too.
HA 2025.4.3 using Zigbee2MQTT.
According to the history this is since the last week now.
Tried rebooting with both the MQTT Add-On’s stopped to see if that would matter.
Question to anyone: How would the ZBT-1 firmware be updated normally?
Everything works and I like the “do not fix what ain’t broken” approach.

Another way is to use the HA Add-on.

It’s one of the official Add-ons available.

I’ve used it in the past to update the HA Yellow and several HA Connect ZBT-1 sticks.
