Zigbee2MQTT running unstable

Configuration Zigbee
1

Hi there,

I am having sporadic issues with my Zigbee2MQTT LAN coordinated network.

Hardware:
I am running the coordinator via LAN. I build a Sonoff Zigbee 3.0 Dongle bridged by a ESP32-ETH01 and running Tasmota on it. Firmware I use: CC1352P2_CC2652P_launchpad_coordinator_20221226

Without any changes I received various erros in the past, which could be solved after various restarts of Z2M Add-on. Recently I experienced the error of channel mitmatch between adapter (11) and config (25) - without any recent modification.
After returning to 2 days old backup everything worked fine again.

Config (/config/zigbee2mqtt/configuration.yaml):

homeassistant: true

There is no definition of PanID, Channel, etc. I am wondering, if changes in my config might turn my ZIgbee network a bit more resilient. What should I adopt?

Thanks for your advices!

Do you require any additional information, which might be beneficial to help me with my issue?
Any comment is apprechiated!

what does your z2m-logs say around the time you have to restart it?

I’m no Z2M over LAN expert but to me it seems you have issues with the connection to the adapter at times hence the restarts are required. Are you hardwired “all the way”? Why your channels are mismatched I cannot say though.

6

Any instructions on this ?

I use an ESP32-ETH01 (with LAN connect). I connected serial Pins to the Sonoff Zigbee Stick (Rx/Tx crossed) and interrupted the serial connection to USB interface on the Sonoff PCB.

On software side I am running Tasmota as IP Serial interface and deactivated wifi. Any information missing?

8

Additional question: Do I get it right, that you guys expect my problem in the hardware and not in the configuration? So which LAN operated Zigbee hardware do you recomment insted?

I have a Tube Zigbee Ethernet/USB coordinator (USB for power, Ethernet for connectivity) My Zigbee2MQTT network has been rock solid with it for over the last 2 years.

Thanks for the advice.
I have te opportunity to quickly get a EFR32 MGM21 PoE Coordinator to a reasonable price.

I want to run it with Zigbee2MQTT. For this model it is stated: “Alpha/Experimental support is now in Zigbee2mqtt but is untested.” which does not sound very promising to me.
Any update, if this does work or should I rather go for the " CC2652P2 Based Zigbee to PoE Coordinator 2023"?

Thanks for your feedback!

For Zigbee2MQTT, a CC2652 is always best, but a lot of people use the EFR32MGM21 already without problems.

Yes if using Zigbee2MQTT then Texas Instruments adapters are preferred, though EZSP support in Zigbee2MQTT is getting better, follow → https://github.com/Koenkk/zigbee-herdsman/issues/319

Anyway, it is generally not recommended to use Silicon Labs EmberZNet based Zigbee adapter over LAN unless using a rock-solid Ethernet network, so especially do not use WiFi, because the EZSP serial protocol it uses does not have enough fault-tolerance to handle packet loss or latency delays.

Also check out → Guide for Zigbee interference avoidance and network range/coverage optimization

I mention there that possible it will be better to just use a very long USB extension cable instead, and should know you can simply buy inexpensive USB to RJ-45 adapters that will convert any network cable into a USB cable. See for example → https://www.amazon.com/Cat6%EF%BC%8CSNLLMZI-Extender-Extension-Connector-Adapter/dp/B08FMLGNQN

Thanks for detailled information!

I am coming from an instable setup I would like to get rif of. So in order to set up a rock solid solution I understand the priority:

  1. CC2652P2 Based Zigbee to PoE Coordinator
  2. USB to LAN extension and keep using my Sonoff Zigbee Stick (CC2652P) - Should I expect any issues as my LAN cable is abt 20m long?
  3. EFR32 MGM21 PoE Coordinator

Did I get this right? Any other recommendations?
