New sensors I wish that can posibel be added ?

[Korsberg]

Hi, i'm using function in HA to charge my batteri with Nordpool and the local calendar, but what I'm missing is a sensor to change charge level (SOC) and it this one --- Forced Charging Target SOC ----

I have an SH10.0RT inverter

In below link it might be a way to implement this ? if so it would be amazing :-)

Thanks for great work !!

I think below link can be to some help ? I hope this can be added in the next coming updates

Should be so nice if we can have at least this one so we can read and update this value :-)

  address: 13145

I can't get this modbus4mqtt to work

I found more info on this page about register ....
https://gist.github.com/rasmusbonnedal

I tested and used the register on above link for 33213 "Forced Charging Target SOC 1" and modified my modbus_sungrow.yaml like this

And surprise I can read the value !!! and if I change on iSolarcloud its read the new value in HA :-)

BUT I can write value :-( maybe some code is missing for that ????

Only thing right now when adding 55% in Isolarcloude its then display 5.5% in HA , no big deal right now, some format thing I believe.
Feel free what you think :-) My very first attempt and I'm so happy :-)

Great work. I recently installed HA and got to know my way around it. Most of the feature requests / functions are there. The SOC slider almost being the best one! Great work on that.

The only thing I think would be great is to use the registers below to set weekday / weekend start discharge and end discharge times. It will then use the "target SOC for Backup" setting for the DOD.

**Tested to move this slider to active in HA "sungrow inverter force SoC input slider update"

And moving Set Force SoC slide to new value its update Force SOC sensor and on the Isolarcloude !! yea :-)**

Now I need to see why its displayed for example 5.3 instead of 53 ;-)
