This is modbus rtu communication and Not supported by solar2mqtt at the moment

@YAYASIMPSON can you share somewhere your experience making solar2mqtt work with PowMr 10.2. My 10.2 (version 79.06, with new 'sci-fi' display) is not recognized at all.

[softwarecrash]

no, they use another protocol that i dont know, so i dont have one of this devvices, i cant rebuild it

[AlexK98]

@softwarecrash , do you happen to know what "Warning_Code" value "2" means? I'm seeing it right now.

[softwarecrash]

Nope

Hopefully, A few useful notes on the correlation of values of settings on POW-HVM10.2M. I have no PV modules so I can't test/see other states.

Status_Flag = 10000 -> Inverter_Operation_Mode = Battery, Inverter_Charge_State = No Charging
Status_Flag = 10101 -> Inverter_Operation_Mode = Line, Inverter_Charge_State = either Bulk or Float

Device_Status = 110 -> Inverter_Charge_State = Float
Device_Status = 10 -> Inverter_Charge_State = either No Charging or Bulk

Output_mode or Operation_Logic values did not change during the observation of above settings.

[AlexK98]

Also, my inverter responds to QVFW and QVFW2 commands

[YAYASIMPSON]

hello sorry now i can't respond you because i have a problem with my inverter i have error 9 and doesn't works since 3 weeks 😔 so i try to repair or change motherboard in waranty and i come here to helo you after.

[AlexK98]

@softwarecrash
on the latest test firmware (2.0.0-Pre6A4) I found a bug - warning is shown on the dashboard for the disabled entity.

It does not want to disappear after browser window refresh or even after HA restart

[AlexK98]

This 'bug' is only visible on very default HA dashboard.

@softwarecrash
I tested values of "Charger source priority" setting and its corresponding PCP commands and actual mode in the inverter:

1. PCP01 => sets 1 => Solar and Utility
2. PCP02 => sets 2 => Only Solar
3. PCP03 => sets 3 => Solar First

PCP00 returns ACK, but does not change active value.

[AlexK98]

One more note for POW-HVM10.2M with 79.06 firmware:

I could not find any references of these values in the Protocols folder.

[softwarecrash]

then its a modified answer, ask your seller for the protocol

[AlexK98]

@softwarecrash already asked and they refused

[AlexK98]

Don't know if this is a bug or not, but despite fans being completely off, the Fan Speed shows 30%

[softwarecrash]

its what your device send
