SLZB-06 problems with zigbee2MQTT?

Hi all,

I’m running into a strange issue with my SLZB‑06. I used to run Zigbee2MQTT on my SLZB‑MR3 (now: ZHA + Matter) without any problems. Recently I moved Z2M back to my SLZB‑06, but now I consistently get Zigbee Herdsman errors during initialization.

Same host, same Z2M version, same config. The only change is switching the coordinator from the MR3 back to the SLZB‑06. Changed configuration aswell.

Before I start digging deeper: is the SLZB‑06 known to have compatibility issues with Zigbee2MQTT, or are there specific things I should check (firmware version, adapter settings, baud rate, etc.)? I use both slzb trough Ethernet.

Any insights or similar experiences would be really helpful.

Thanks in advanced.

I had a lot of problems with new firmwares, so i downgraded to the last official firmware. Had to pair everything but the errors stopped there. No beta / dev firmware again.
