Modbus connection failures

[lazy-pete]

Hi, I’ve been getting a lot of connection errors that seem to result in my Integration (and automations dependant on it) failing. Along the lines of

2024-04-25 23:52:17.021 WARNING (MainThread)
[custom_components.solax_modbus] Unable to connect to Inverter at 192.168.1.25:502

I think this means the actual Modbus connection is dropping out, though I don’t know why - it’s solid the rest of the time. I tried to set up an automation to restart the Modbus service when it did this, but couldn’t find the service:Modbus anywhere. Nor can I find any reference to Modbus in my config.yaml not if I run this command in terminal -

yet most of the time I can read and write to my inverter over the 485 Ethernet / elfin WiFi setup I have just fine - https://github.com/Jumpy07/Solis---SolisCloud-and-Home-Assistant - not using the SolisCloud stick, so single master (unless I need them to troubleshoot the inverter itself).

I’m assuming Modbus is what’s installed with this integration, but a bit puzzled as to why I cannot find it anywhere, but it still works !

I have seen the odd post referencing tweaking the 485 module ip address / settings as helping, but am not quite sure how to go about that / what to tweak if that would help.

I see lots of bug tickets created with various connection issues recently, although when I get to the FAQs it suggests having a non functional connection is the culprit - not the integration. Fair enough - but how do I troubleshoot that ?

Cheers,

Pete
