Incorrect libbi status

[plord12]

I've just had a fault and the libbi controller was alternating “Inverter undervolt” and “Inverter overvolt”.

I noticed the library gets these statuses wrong. We should have, I believe -

• 151 - Inverter Undervoltage
• 152 - Inverter Overvoltage

Actually, as per user guide ... i guess all the statuses from the user guide should be added.

I'm noticing status 58 cropping up randomly at night - presumably due to the generation CT recording a slight negative value.
Code 58 (and the others) should be included for an easier understanding by the user

Thanks for this.

I should add i have had a "103" while upgrading my inverter today, no idea what it means though.

Can you link to the user guide please?

I think the user guide is wrong for codes 172 & 173.
Recently my controller was reporting "BMS Undervoltage" while the api was reporting "BMS Charge Temperature Low".
All I deduce from this is 173 should be "BMS Undervoltage" so maybe swap 172 and 173 (assuming we can't ask Myenergi for a definitive answer!)
