Recently my 3 Zigbee motion devices stopped working. I can interview them from eisy. Ive tried deleting them and adding back in but they dont add.

Zigbee checkbox is checked in IOX. Worked great for a year.

I have Upgraded packages, unplugged and replugged dongle, and rebooted.

Any clues before I open ticket?

Have you tried a reboot that includes actuallypowering off your eisy?

Yes, I also plugged in the zmatter device into a different USB. Still not working.

So when you click on the Zigbee menu at the top, you get the various options (Add a Zigbee device, etc) right? That means that it's seeing the dongle. The next thing to try would be to try and factory reset the device you want to add, and then try adding it back. This usually involves something like holding down a button on it while powering it up, or some similar procedure. See the instructions that come with the device.

I have a similar but slightly different issue. I have had the dongle for awhile and finally decided to get it installed and operational to start testing some Zigbee switches.

I am running 6.0.5. Installed the dongle, have the configuration options enabled for all the technologies and rebooted the EISY. On the main admin UI, the Zigbee menu shows !ZMatter Zigbee not responding

I saw that someone went back to 6.0.4 and their's started working again. I don't see where I can go back to 6.0.4 otherwise I would have tested.

The Z-Wave and Matter menu shows various options.

Here is what I am seeing in the Zigbee log:

Did you just reboot the eisy or did you power it off and back on? If you didn't power cycle it, try that.

I have tried both. I just did a power cycle and here is the log. It seems like it is communicating (sending and receiving) but then seems to stop. While I don't know what a log on a working system looks like, I did notice these log messages:

Wrong default trust center key size 0

Error returned from (err = zbee_ef_set_initial_security_state(zbee, NULL, zbeediscover_on_fail, NULL)): Wrong packet from the network or Discovery got bad data (stick communication failed) (-9)

I had same issue. Support ticket. They rolled me back to previous version and all is good again.

That's really odd. I have a eisy and a Polisy, both with ZMatter dongles, working fine on 6.0.5
