read alert field

[CFenner]

I would like to see the alert field in home assistant. Any doubts about adding this?

Detailed description

I would like to read webdata_alarm and make it available as a field in HA.

var webdata_total_e = "0.3";
var webdata_alarm = "F13";
var webdata_utime = "1";

var webdata_alarm = "F06F11F13F23F24F26F27F31";

I'm using Bosswerk MI300 / Deye SUN300G3-EU-230. Is this also available on other inverters?

Context

This would be nice to have for diagnostics.

I see the same field in my JS source, so we can probably add it. We need to add it in the python-omnikinverter library first though :)

We are working on it, it's just a puzzle to find out per source_type where this value is.

@CFenner Do you have a mapping of these error codes? According to certain Omnik docs like https://download.solarclarity.nl/2015/04/UserManual-OMNIK-3K4K5K-TL2.pdf F13 means that the device is overheating...

If we can find a consistent mapping for all these devices we might be able to provide a friendly representation in the UI, instead of raw text.

I'll check if I can find an error-code mapping in the TCP stream in the meantime.

[CFenner]

No, I don't have a mapping. It's definitely not overheating, current production is very low. I asked Deye for it.

[robbinjanssen]

So we found a few sources that have some mapping, for example: https://download.solarclarity.nl/2015/04/UserManual-OMNIK-3K4K5K-TL2.pdf

or in dutch: https://www.solar-nu-webshop.nl/data/upload/files/1911-omnik-handleiding-01-usermanual-omnik-single-phase-inverter-installdutch.pdf

But if it doesn't match your current problem, the mapping is useless.

@CFenner How useful is this field without knowing what's up?

I can see use in knowing the value, but wouldn't want to unnecessarily scare users because of some non-empty error code/value.
