CRCError: CRC validation failed
My logs are full of the following error message:
2023-12-17 17:35:13.681 WARNING (SyncWorker_1) [custom_components.solarman.solarman] Querying [512 - 597] failed with exception [CRCError: CRC validation failed.]

My inverter type is Sofar HYD 5000 ES (SM1ES150). Firmware G360.
The data seems to be read ok, with the exception of 0x022B - "Inverter alert message"; this appears to be classed incorrectly as an alert for my system.
Same with HYD 6000 (ZM1ES060) with Firmware G363. HA on raspberry Pi 3+.
Usually 30% of readings fail with that error, the read is ok after 1-2 attempts.
CRC errors come from uModbus library.
Already tried two different stick loggers 17**** and 27**** . Same results.
I'm getting this as well. I've worked round it by upping the retry limit to 4
@sjmtlewy I'd suggest you put a sleep between retries. It helped. 1 second is enough in my case.
Have a look at #523 too. I left a piece of code you could try.
