Gen 4 X1 Hybrid suddenly stopped working with integration

[M0LTE]

My gen 4 SolaX X1 Hybrid + ethernet modbus adapter combo has suddenly stopped working with this integration - my sensors at least are all "Unknown" value.

I have removed and re-added the integration with no success.

Where do I start please?

I have logs:

Can you roll back to 2022.12.6?

I added in some extra BMS info after 2022.12.6 and it seems like not all Inverters like it. A Gen3 is the same but:

SolaX error reading holding registers at device 1 position 0x206

As they are in different places between Gen3 and Gen4

But you both get the following:

val = datadict["measured_power"]
KeyError: 'measured_power'

Not sure why at the min? I'll probably remove that whole BMS section as it's pointless unless you want to know your battery serial number.

How many batteries do you have connected to your Inverter?

[M0LTE]

3 - one slave, two master.

@wills106 Why is it reading holding register 0x200 ? I dont see any reason why it should read that address

[infradom]

sorry BMS registers

About to attempt downgrade

@wills106 Downgrade successful and I've got my sensors back. Thanks.

The BMS entities worked on my Gen4 after I enabled a couple of them
Tom, did you manually enable BMS options when it went wrong? They are disabled by default if I am right ..

[wills106]

Another report #263 (Third now)

Going to remove releases after 2022.12.6 and then remove this BMS stuff.

I am talking about having lost all of my basic sensors like battery state of charge, current power usage etc. Didn’t manually enable any disabled entities. I must have not spotted it was broken after doing my recent upgrade to latest.

As you didn't enable the BMS sensors it shouldn't be reading them anyway.
We will look into that.

Also it's possible these registers are missing on certain Inverters. I don't know if this is a firmware issue or a hardware revision issue.
I have had this in the past though where Inverters are missing registers.
