Zigbee2Mqtt - error: z2m: Error: Failed to connect to the adapter (Error: SRSP - SYS - ping after 6000ms)

Setup, Configuration and Use Installation
1

Hi,

I upgraded from OH 4 to 5 now and I have a lot of trouble getting ZIGBEE2MQTT to work. I´m using a Sonoff Dongle-P, flashed the latest firmware and I can´t get it to work with Zigbee2Mqtt, always getting this error:

error:         z2m: Error: Failed to connect to the adapter (Error: SRSP - SYS - ping after 6000ms)

I can easily shutdown my pi and switch back to my OH 4 Installation and the Zigbee2Mqtt and the dongle work flawless, so it´s no technical malfunction.

Here is my configuration.yaml:

I´m trying for 2 days now, but I can´t find the problem. Maybe someone has an idea here?

thx in advance!

Zigbee2mqtt has its own forum which is linked on Homepage of zigbee2mqtt or you may have a look in the users guide of z2m

yes, but I´m not quite sure if this is also a OH5 problem!? Maybe someone is here who uses a Rpi4, Sonoff Dongle-P and OH 5 just like me but without those problems…

edit:

Ok, after chatting a week with ChatGPT, I finally found the problem now: piVCCU3 !!

The raw-uart seems to reset all serial devices every few seconds… After

sudo systemctl stop pivccu

Z2M just started! Well, solved one problem, created a new one: I absolutely need piVCCU because of my homematic devices…

edit: Ok, I switched from piVCCU3 to debmatic, now it works all fine!! Thx!
