@reichelper could you re-flash Zigbee on the latest XZG firmware, even on the same Zigbee version, and then re-check this issue ?

Same for me.
Since Update to one of the last 4 new ESP32 Firmwares i get the 0 or ? Firmware Version.
I re-flashed several times.
Only in Console i get the correct Version output.

Also cleared browser cache and tried in private mode - no Firmware Result.

@xyzroe
I flashed the latest ESP32 firmware.

You need to re-flash Zigbee

I just tried to flash the Zigbee FW and the UZG-01 hangs up at 72,30 % and the red LED is flashing. Whats this?
UPDATE: I restarted the Zigbee Coordinator (Power off and Power On), then the device started up, but wont connect any more to ZHA. What should i do now? I retried to update the Zigbee FW Update several times now, but without any success. Check Zigbee Version in Debug Console now shows: | [ZB] FW: Unknown! Check serial speed!

Please help me out, no device is working now.

UPDATE: Glad, got it back to life! I had to disable ZHA and MQTT first and before startig the Zigbee Update. Never found a Point in Documentation about this before, now i had read this. Update started, processed and finished. Now the Details in ESP32 are working again with correct FW. Thanks!
