Not getting DC value on multiple mppt with single phase inverter

[ivanfmartinez]

I just installed this component v2.6.6 and found that I can see only a single DC Voltage (and Current) with value of -0.0 V. The AC and Energy values appear to be OK.

My inverter is single-phase version but running connected to two-phase AC (AC Voltage and Current are ok) with two DC MPPT strings .

@alexdelprete I have made a test a test branch (based on v2.6.6) to try to make it define single or multiple mppt sensors.

Can you check to see if you agree with this idea : v2.6.6...ivanfmartinez:ha-abb-powerone-pvi-sunspec:check_mppt

I know that there are a multi_mppt_nr on the code but I have tried to make just little changes now to make it works in my system with v2.6.6, as I have seen that the master branch have a lot of other commits.

Hi Ivan,

I noticed this issue being reported by a couple of users.

I'm in vacation for 2 weeks, will check your PR when I get back, thanks a lot for the contribution. I'm not a developer (last time I coded was 20y ago) but since I use HA I started again but for me everything's new so I mainly tinker to make stuff work as good as I can.

Will give you a feedback as soon as I'm back home.

Alessandro

Hi @alexdelprete ,

i have just update my HA instance and updated my changes to be compatible with your latest changes

v3.1.5...ivanfmartinez:ha-abb-powerone-pvi-sunspec:multi_mppt_2023_10

If you have time now please give the feedback

Did you make a PR?

Not yet, just send the diff here before to check what you think.
But I can make the PR if you agree or make the PR and discuss there.

Is my first time with this project and I did not know how you prefer to work.

Yes, prepare the PR so we can discuss there. Take into account that I'm not a developer (I was 20+ years ago), and I'm not an expert on GitHub etc., I'm learning but if you can contribute and help me I am more than open to receive support. :)

Thanks.
