Issue related to

Sunsynk / mbusd Home Assistant Add-On

Describe the issue/bug

The AddOn stopped working some days ago an stops with the error in the logs. I have checked all wiring an the RS485 Adapter an they work fine, also rebooted the inverter and checked the settings.

Expected behavior
The AddOn worked without problems over the last year, i don't know if something was changed in the last update what causes the problem.

The error seems to come directly from the driver (umodbus). I doubt there was a change on umodbus (it hasn't been update in a long time)

Please use pymodbus as the driver

Ideally you should not connect directly to a serial port, but rather through mbusd, in the long run that should be a lot more stable. You can use the mbusb addon in the same repository

I also seem to be having the same issue. I'm using pymodbus and a serial gateway. It's been a problem the last few days. I think since I've updated. Seems to sometimes work for a bit after a restart. Let me know if I should add my config and logs.

I've changed the driver to pymodbus and port to "" so the addon used the debug device. After a restart the addon is working fine now 👍

If you still have issues the next step is going via mbusd

If you use pymodbus it unlikely to be the same. But pymodbus was updated, so best to post your own logs&cfg
