PoE powered UZG-01 does not come online after reboot

[GD-Dal]

Not sure if this is related to the switch or the UZG-01
If I restart the UZG-01, it does not come back until I shutdown the switchport and turn it back on.
Until then, the UZG network port blinks for a second, then goes dark. Blinks for a second then goes dark, etc.

The switch is a Cisco Catalyst 9300 of model C9300L-48UXG-4X
The port settings looks like this:

interface GigabitEthernet1/0/31
 description UZG
 switchport access vlan 1098
 switchport mode access
 device-tracking
 speed 100

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

[xyzroe]

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

[xyzroe]

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

[GD-Dal]

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

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

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.

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

It hasn't helped

[xyzroe]

@mercenaruss could you help us ?

[zoptooniek]

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.

@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 support@zig-star.com and we will try remotely to debug this.

[zoptooniek]

@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

[xyzroe]

Could you try factory reset after updating to 20240607* ?

[zoptooniek]

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]

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

[zoptooniek]

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