I had a similar problem when setting up Zigbee2MQTT and found that setting base_topic to UZG-01 fixed it.
Iāve transferred from a Sonoff ZBBridge Pro to the UZG-01 and, using it in LAN mode, have got Z2M working with very quick pairings with zigbee devices. But, and I may be very confused here, how do I pair the wifi devices I previously had paired on the Sonoff?
Huh, pairing wifi devices? Wifi devices use IP addresses, you donāt pair those?

Iām very new to all this so my language may be amiss. Perhaps importing? When I was using the Sonoff bridge with, for example, wifi smart plugs, Using the ewelink app, I had to press the button on the side of the plug to enable the plug to be found and I could then see it in the list of devices attached to the bridge. Those smart plugs are no longer visible in my list of devices, hence my question.
Do I still need to use the ewelink app to find the wifi devices? Some of them are in quite inaccessible places so very difficult for me to press their buttons.
Zigbee coordinators and wifi devices have nothing to do with each other. A Zigbee coordinator enables communication with Zigbee devices over a Zigbee network, wifi communicates over TCP/IP and do not need a coordinator.
yes, or use the Sonoff Lan integration (in HACS). better make a new topic about this, it has nothing to do with Zigstar.

As you can see, ZigStarGW-FW has not been updated for some time, and itās now transitioning to archival status. 
the same will happen with UZG firmware
Iām pleased to introduce a modern alternative: XZG Firmware, which is currently in its final testing stage. 
We introduced new functionality:
- Zigbee OTA - Install new Zigbee firmware or change role Coordinator / Router / OpenThread using only the Web UI of your gateway
- ALL DEVICES - All previous devices what are working over LAN or WiFi are supported : Olizig PoE, LilyZig PoE, ZigStar LAN and side HW developers
- NVRAM Erase - NVRAM using only the Web UI of your gateway
- Custom DNS servers - Yes (when DHCP is off), Ethernet and WiFi
and many other things: CHECK ALL FEATURES

Hi @mercenaruss, Iāve sent you an email and two but yet to get any response on what to do next with my first UZG-01 that needs to be restarted daily as devices go offline.
100% now that I dont see this issue on the other UZG-01 that I have, solid now for 7 days
Iām having issues with the UZG-01 v0.2, tried every firmware available with no success. It was stable with the 20221226 (I think thatās the correct firmware version), after I stupidly upgraded from that stuff go offline. One day itās an Aqara sensor, next day a Elko thermostat, then a Hue plug. I re-pair the devices and then next time some other random devices go offline. Would anyone happen to have the 2022 firmware for the P7 chip available? Iāve tried support but no luck so far.
This proved to be true. A UZG from Elecrow does not have the WiFi reconnection failure, and node link is more reliable.
Also, just installed an Ethernet drop at that location and the gateway is happily working off POE. Now I can connect the RPi hosting Z-Wave JS UI over Ethernet too.
I gave up on the UZG-01 for now. It turned out even the 2nd one I got went offline for no reason, rebooted and now it goes offline automatically every 3-4 days for no reason.
Too much grief with these things. I might come back to these at some point however it looks like ā¬70 down the toilet.
Trying the SMLIGHT for now which is also not perfect, took me 3 tries to get a working one. Will see how that one gets on. Otherwise back to the USB Sonoffs.
Its a nightmare really as I am away now at the weekend for a couple of weeks with my flight back at night, will probably be coming home to with a dark home with nothing working.
I havenāt tested enough, but so far my experience with Zigbee reliability stuff is far below Z-Wave.
When I started using Z-Wave it was set and forget. With Zigbee Iāve seen all kinds of hiccups.
- ZHA doesnāt support as many devices and capabilities as Z2M.
- Z2M stops if it loses connection to the coordinator and wonāt restart automatically.
- The watchdog will try to restart it a few times and then quits.
- The end result is that if the coordinator disconnects even briefly all the Zigbee stuff goes down until you manually start Z2M.
This issue is open about this but is not being worked on.

Yea I actually had a pretty stable ZHA setup for over 2 years on the sonoff dongle-P, I cant pinpoint what happened actually. I might have expanded too much or some update broke it. I decided then to get an Ethernet coordinator when I read some glowing reviews about them.
With the UZG-01 in hand I migrated slowly to Z2M. I have the Z2M and MQTT in its own docker container, it is not running with Home Assistant. However experience hasnt been great with the UZG-01.
I ordered an SMLIGHT SLZB-06 and 2 of those arrived as duds, so I had to get support to send me a 3rd one which finally works. In the meantime I got another UZG-01 in the hopes the first was a dud.
At first the new UZG-01 was quite stable for 4-5 days, however on the new firmware which keeps updating every other day for one bug fix or another (there should be release cycles), I cant seem to find a stable release. With the latest firmware, it lasts 4 days compared to the older UZG-01 which lasts 2 days before I have to hardware restart it.
I gave up on these for now, paper weights really now. Not blaming you @mercenaruss, seems like you are a one man team so I can understand not easy to support but based on open issues in git and on this forum, there seems to be a serious issue either with the zigbee chip or something else that is causing hangups.
I am using the good SLZB-06 now, so far 2 days no reboots and signal is stronger compared to the UZG-01 so plus there.
Cant recommend these at the moment, but I hope to revisit them in a couple of months, I am hoping it is a firmware and not a hardware issue. Shame to leave them as paper weights and hoping I can recommend these in the future once the firmware is stable.
Currently we have a single developer and is Koenkk,he is well aware about problems with firmware for Zigbee chip.
He is trying to solve it: HERE ,itās the same for all people who are using Tuya devices,is a problem on SDK from Texas Instruments,we simple people cant do nothing about this. P7 is working only on last SDK, P2 is still working with old SDK and is kinda stable. I was thinking many time to go back to P2 chip and forget about all this,but i see things are moving forward.

I understand perfectly the problem,you can see my upper post.
From other hand we have firmware on this devices:
- ESP32 firmware,what is answering for LAN and Bridge connection.
We moved to unified firmware XZG because we was able to add there OTA upgrade for Zigbee.
Long story short: SMLight forked our opensource firmware and of course worked on it,but closed the source files when they added OTA.So thi why we have now so active development. - CC2652P7 firmware - what is not stable now,because of issue mentioned everywhere.
I still hope issue with P7 will be solved soon by Koenkk or Texas Instruments.
Currently i recommend to all - upgrade to XZG - there you can try 1-3 zigbee firmwares, for many people 1 of 3 zigbee firmwares solved the problem they had,but all resumes to Tuya devices.

Yes,this is a problem with Z2M is not recovering connection by itself.
Hello @all , today was discovered some strange things on some boards with XZG firmware.
People who dont have network coming up please follow next procedure:
- Download NodeMCU Flasher
- Download - UZG-01 Firmware 0.2.6
- Flash UZG-01_v0.2.6.full.bin
Your network should be up and running.

Thanks @mercenaruss
yes I am already on the firmware 20240316 but still having the issues with hangups, not sure if related to the P7 chip or ESP32, weird thing is I have 2 of these UZG-01 but they behave differently. One hangs after 1.5 days the other after 4 days so behavior is inconsistent.
Anyhow I am going to remove my tuya stuff slowly and restest in a month once I am back from my holidays. I am hoping we have some more stable firmware then. Hoping have more positive results.
One thing I also notice that the LQI for the SMLIGHT SLZB-06 is much higher than UZG-01. Is it because the P7 chip still doesnt support +20dbi ?
Hello guys!
I am observing this thread since i got mine UZG-01, about 2 months ago.
since I connected it to my HA and replaced sonoff dongle (btw that migration went without any problems and with no need to reconnect anything!) i have 0 problems with the coordinator.
So i am very confused by the problems discussed in here and the explanation that it is a problem with P7 chip itself.
Grantedā¦ I am on a pretty old firmware. I like to jump on the latest, and greatest software immediately when it arrives, but reading all those issues i am afraid of doing so. Am i missing something? Am i just lucky or that old firmware is saving my butt, and I should definetally not upgrade any time soon?
I wouldnt touch it then 
I think it all depends on the number of devices. That zigbee firmware has a NWK table full issue whereby things will start to be slower.
I would stick to the firmware on the ESP32 as well. Not sure how stable the new XZG firmware is at the moment.
