Adapter Errors with Danfoss Ally + Sonoff Dongle plus E

[soframel]

Hello,

I have a new setup using Sonoff dongle plus E + zigbee2mqtt + HomeAssistant. I have migrated all devices from my previous setup (Conbee II / deconz with openHAB) except for Danfoss Ally thermostats: I am able to pair them in zigbee2mqtt, but then I get errors every time I try to send a command to the thermostat. Sometimes the error also are considered as fatal by zigbee2mqtt, which then restarts.

For example:

The log above was from an older model, the "eTRV0100", but my other models are all more recent "eTRV0103" : I tried with one of these, and I had the same errors.
Finally I had to delete them from zigbee2mqtt so that my setup was stable again.

I saw a number of other posts were these thermostats work correctly, so I suspect something is wrong in my setup.
Last week before beginning this migration, I had tested the Danfoss Ally with the Sonoff dongle directly from my latop, using zigbee2mqtt in docker, and it worked fine.

One difference that I see with the current setup (on a raspberry Pi 4, with a HomeAssistant OS installation) is that it is located further away and I am using switches as routers (one Innr SP220 switch, and also one older OSRAM switch, but I couldn't check in the map view if they are really used for connecting to the Danfoss Ally, because zigbee2mqtt crashes before) instead of a direct link : could these be the cause of the problem?
Any idea what I could try ?
Thank you.

I saw an additional error in the logs, shortly before the fatal error: ROUTE_ERROR_NON_TREE_LINK_FAILURE

In order to confirm if it is a routing problem through the switches, I moved my raspberry pi closer to one of the thermostats, unplugged the switches, and reset/discovered the device again: in this setup where it is linked directly to the adapter, it works perfectly, I am able to send commands, etc (and I finally saw the event stating that the thermostat was configured correctly).

Now I moved the raspberry again in its placed and plugged the switches again. For now, it still seems to work, even though I see in the map that it is connected through one of the switches.

So, should I do this for my 5 other thermostats (move the adapter so that it is directly linked during initial configuration)? is this generally recommended?
or would it be better to buy a better device for routing zigbee network for upstairs? (I saw it is possible to flash the Sonoff dongle with a router firmware, for instance)

Thank you for your advice.

Hello,
just in case anyone else encounters this: I saw in the discussions in this issue #23855 that the same kind of errors happened on the Sonoff dongle E when using the adapter version 7.4.3, which I was using, and that the firmware version 7.4.4. seemed to work better: So I updated my dongle's firmware, and for now, it seems to work, also for a thermostat which I just paired through a plugin/switch used as router and not a direct link.
So I hope the problem is solved, and I will now try pairing my remaining thermostats.
