PoE powered UZG-01 does not come online after reboot about xzg HOT 17 CLOSED

@mercenaruss could you help us ?

I have the same issue with UZG-01 (POE-0.4)

from xzg.

I have the same issue on a UZG-POE-0.5. It doesn't always survive a reboot and am left with the NIC lights pulsing off and on again 3 times in a cycle.
Sometimes, forcing a reboot by bouncing the switch port will make it spring back to life, however not always and I have to leave it powered off for a little while before powering it up again.
However, when powered by USB, it will not recover at all and the only way to recover is to flash back to 0.26 via the webflasher.

I have 2 of these devices, i think both with the same Hardware revisions based on the Status page (ESP32-D0WD-V3) and the sticker on the bottom (UZG-POE-0.5) but only one of them has this issue.

I reboot the other one on a daily basis to install all the new firmware updates and it always reboots fine with no issues. (Just as well really as that one is in a remote site!)

Happy to try any suggestions to help pinpoint the issue.

This seems to have done the trick so far.
I have been able to reboot the device several times with no issues :)
Thank you!

@xyzroe - Performed a few more reboots and fw updates and all seems good!
Happy for the issue to be closed

Please provide additional information about the hardware version of UZG-01 (label on the bottom).
It will also be useful if you provide a photo of the inside of the device, for a greater understanding of the revision of the board.

I don't know how to open the box, though. It looks solid

from xzg.

Ok. No need. I'll check and come back.

You could try to change "pwrAltPin": 5, to "pwrAltPin": -1, in your configHW.json

from xzg.

Didn't help at all.
But I discovered one thing though.

I turned of power on the switchport and powered up the UZG-01 via USB-cable instead.
And when I rebooted the UZG-01 some time later, the same thing happened.

The network port just blinked as before until I unplugged the usb cable, waited 10 seconds, and replugged it.

This is becoming the most unstable piece of hardware I have purchased for a long time.

Not possible to reboot without hassle
LQI is low on all zigbee devices.
Zigbee2MQTT crashes regularily because loss of connection

Let's separate Zigbee and ESP issues.
Problem with LAN port is ESP issue.
But low LQI as well as loss of Zigbee connection are Zigbee releated issues. Find more info in Zigbee firmware repository.

I will look for some solution to made ESP32 works with LAN port more stable.

It hasn't helped

@tonius7570 @zoptooniek Try to change "pwrAltPin": -1, to "pwrAltPin": -1, in your configHW.json.
If any of you have some time,please drop me an email [email protected] and we will try remotely to debug this.

from xzg.

@mercenaruss changing this made no difference to me. I'm still in the same situation.
I have also updated the fw to 20240607.1 and the issue still persists

from xzg.

Could you try factory reset after updating to 20240607* ?

from xzg.

@zoptooniek could you check it later to confirm, and if no issues - close this issue ?
