Sonoff Dongle MAX (dongle-m) stability issues. Poor result

[ced2git]

Hello,

I have recently migrated from my sonoff dongle plus towards the dongle max and since then i 've strange behaviour on my zigbee networkk.

The dongle is connected in PoE setup and i’ve disable the Wifi to avoid any pertubation. While my network was stable with my previous sonoff dongle, i have now a series of end devices (switch without neutral, plugs etc…) not behaving correctly.

I’ve removed these devices from the network and added again but the issue is still present.

If a activate a plug manually with the physical button associated, i will see in HA Z2M the device reporting a change of state but if toggle the state from HA dirrectly, i will get an error like

[08/02/2026 14:12:22] z2m: Publish 'set' 'state' to 'Lampe salon droit' failed: 'Error: ZCL command 0x70b3d52b6002fa33/1 genOnOff.on({}, {"timeout":10000,"disableResponse":false,"disableRecovery":false,"disableDefaultResponse":false,"direction":0,"reservedBits":0,"writeUndiv":false}) failed (Delivery failed for '49374'.)'

Most of my devices were with a LQI above 100 before the migration and now there are al with an LQI of 60-70 …

I’m running version

Reallly disapointed by the new dongle which is supposed to be more powerfull than the previous Sonoff Dongle-P

Hi,

I had a very similar issue.

After upgrading from the Dongle-E to the Dongle-Max, Zigbee2MQTT couldn’t reliably control my devices anymore. They were still reporting their state correctly, but commands sent from HA often failed. Even worse, some devices would randomly drop off the Zigbee network.

I fixed it by deleting the Zigbee2MQTT stored configuration in Home Assistant and setting it up again from scratch. After that, everything went back to normal.

Hope this helps.

Maybe it would be a good idea to share your issue in this thread where there is active official participation:

Please believe us that we are working hard to debug the issues and fix the bugs. We have just released v1.0.6 beta version. If you are still interested, please try it through Web UI -> Firmware -> ESP32-D0WDR2-V3 -> Check for Updates -> Beta -> Flash Firmware V1.0.6. [image] Note: You will need to refre…

According to the latest updates there, there has been discussion about LQI-related issues.

Thank you very much for using Dongle Max and very sorry for the issue.

as @KMMT has pointed out, we’ve noticed that migrating ZBDongle-P to Dongle Max from existing Zigbee2MQTT installation may not work well. Starting from a new Zigbee2MQTT installation (or deleting configuration files of existing Z2M) fixes the issue. We are working on the issue and want to provide a smooth migration.

By the way, v1.0.7 stable firmware for ESP32 has been released. It performs even better than v1.0.6.
