HA stopped working

[Willzs]

Hi all
My HA integration has been working without issue but the last few days I just get a connection error and all values say unknown. This is the error it shows:

Error connecting to inverter (friendly name: ""). Error reading registers. Type: RegisterType.HOLDING; start: 31000; count: 43; slave: 247 from /dev/ttyACM0: Modbus Error: [Input/Output] No Response received from the remote slave/Unable to decode response

Does anyone know a fix for this?

Usual quick checks

1. Broken wire(s)
2. Inverter needs restarting
3. HA needs restarting

If that doesn't make it work, then check the finer details on settings.

I've tried those things and still get the same issue. I've not changed any of the settings so not sure why they'd effect it?

It's a KH8 inverter. What was the fix for yours?

1.60 master, 1.02 slave, 1.58 manager

Nothing yet. I think the modbus table changed or the modbus protocol? frame?.
I updated the inverter and HA on the same day, so many variables :\

That's what I'm thinking mine is as it was fine before. I've emailed fox and asked the question.

possible to reverse-engineer the new table, but "aint nobody got time for that"

KH7 with same FW versions for me, and Modbus is working as normal here.
