Connections problems with Sonoff Bridge Pro

Configuration Zigbee
1

Hello together,

I would like to reduce the systems that I have at home to minimum. Because of that I have started with Zigbee. Unfortunately I have since months issues with the connections with the Sonoff Bridge Pro. The connection work at whim. Sometimes I can’t start it (Zigbee2MQTT Addon), then I can start it but after day or two go back offline. Sometimes after day or two go the addon by itself again online…

My Home Assistant is running as Virtual Machine on my NAS in cellar. Because of that I didn’t take any USB-Dongle rather the Sonoff Bridge Pro that is about 50 cm form the access point and between is only a thin wall.
On the Bridge is the Tasmota 12.4.0.2 by Theo Arends.
In the logs of Home Assistant I can find only this:

Directly (using IP-address in the Web browser) I can connect with the bridge. It take indeed some seconds but it work. I use fixed-IP for the bridge.

I hope You can help me.

Thank You,
kamil

Probably better if you ask such questions in Zigbee2MQTT discussions or Tasmota discussions as it sounds like the issues you have is with Tasmota serial server/tunnel and/or socat for Zigbee2MQTT:

https://github.com/Koenkk/zigbee2mqtt/discussions

https://github.com/arendst/Tasmota/discussions

Also, it is strongly discouraged to use a Zigbee Coordinator serial adapter over Wi-Fi. See:

https://www.zigbee2mqtt.io/advanced/remote-adapter/connect_to_a_remote_adapter.html

WARNING

WiFi-based Serial-to-IP bridges are not recommended as the serial protocol does not have enough fault-tolerance to handle packet loss or latency delays that can normally occur over WiFi connections.

Regardless, even if not the root cause of your specific problem you should still also be aware that placing it near your WiFi access point / router is a very bad location and your WiFi access point / router Wi-Fi signals will drown out its Zigbee signals and make its Zigbee reception extremely poor at best.
