Additional context Add any other context about the problem here.

My inverter looks to exist: elif seriesnumber.startswith('H34'): invertertype = HYBRID | GEN4 | X3 so not sure why "unrecognized inverter type - serial number : unknown" fails. and : SolaX: cannot find serial number, even not for MIC

Guess can be related to that the inverter is not found.

I did try to update this two times and same every time.

Please let men know if I missed to add som info or what to test to fix it. Maybe hardcode:

Are you using a Baud of 19200? Is your Inverter configured for the standard address of 1? I would also double check you don't have the A/B wires the wrong way round.

johaaaanz commented 1 year ago

Hi. Yes the Baud is unchanged and still on 19200, same for Address its 1.

Also the wires is unchanged. All stoped working after i guess home assistant os (or core) upgrade, i tested it a few weeks ago but then i think i managed to restore to last full backup and it was sorking as long as i did not upgrade, which i did again today when it failed again.

Forgot to mention that i run om RPI 4 using ssd if that maybe matter in some way.

Just found alot of these also:

[core-ssh config]$ ha core logs 2023-05-28 22:31:35.210 WARNING (MainThread) [homeassistant.util.async_] Detected blocking call to sleep inside the event loop. This is causing stability issues.

Detected blocking call

That's normal with RS485 - USB adaptors. https://github.com/wills106/homeassistant-solax-modbus#known-issues Not ideal I know.

Edit: Just reread this, did you have this Integration working at one point?

johaaaanz commented 1 year ago

Edit: Just reread this, did you have this Integration working at one point? Yes it have worked fine for several months before. And running automations that worked great.

Maybe its just my setup or a RPI problem caused by one of the home assistant upgrades i made as it looks like im the only one.

I did get the same result/failure once before, in the beginning of May but then I managed to restore to the old version and have not updated until now. In hope that either a bug was found in a HA part or some one got the same in the modbus integration (as im terrible at python i just waited and hoped for this to get found by someone that understand this beter that I )

However now restore did not work when i tested, not sure you can rollback home assistant os upgrade (and thats why I guess the problem is related to the os upgrade more that the ha core upgrade, as all was working just fine before.

But guess its hard to place a bug on home assistant os if im the only one having a problem.

Have you tried to power cycle the Inverter? It doesn't happen very often but I know a couple of people have had to do that as they lost comms with the Inverter before.

johaaaanz commented 1 year ago

Have you tried to power cycle the Inverter? Thanks for the suggestion. I did try it now but still fails unfortunately.

johaaaanz commented 1 year ago

Did a reinstall and restore of backup.. No clue what broke but now it works again, and im glad!
