How to add GEN Charge Battery current & Gen force for DEYE ?

[man55]

Hi, thanks again for the great integration!

I have DEYE-SUN-6K-SG03LP1-EU WiFi

It would be nice to add a settings sensor to adjust the charging current from the generator. I already added "Grid Charge Battery current" according to the Guide, but I didn't find how to add a similar option for the generator "GEN Charge Battery current".

I would also like to add “Gen force”, this option is available in the inverter, it forces the generator to start.
Generator(AUX input) voltage and frequency would also be very helpful.

I read the Custom sensors section, but I don’t even understand how to approach this.

I figured it out when I re-read the custom sensors section a few more times.
I was able to add the sensors I needed.
The most difficult thing in this is to understand the Chinese PDF in search of the necessary sensor numbers.

The modbus document is not the most pleasant read. It could be inverter & version dependent and may also depend on you install. Do you use it as an AUX out/have a generator connected, etc.

Glad you got it working. If you have any tips for the community on having a generator connected, and suggestions to the docs would be appreciated.

I found some sensors&settings and tested their work on my DEYE-SUN-6K-SG03LP1-EU:

    NumberRWSensor(226, "GEN starting capacity", "%", max=50),
    Sensor(181, "Generator voltage", VOLT, 0.1),
    Sensor(195, "Generator status"),
    Sensor(196, "Generator frequency", "Hz", 0.01),
    NumberRWSensor(227, "GEN charge Battery current", AMPS, min=0, max=135),

These work, but have not yet been sufficiently tested in practice:

    NumberRWSensor(223, "GEN max operating time", "h", 0.01, min=0, max=4),  // operating time before shutdown for cooling
    NumberRWSensor(224, "GEN cooling time", "h", 0.01, min=0, max=2),  // generator cooling down time
    Sensor(62, "Day GEN Power", KWH, 0.1),
    Sensor(83, "Day GEN Time", "h", 0.1),

The most interesting thing is Generator status, which takes on different values ​​depending on the status:
16 off,
272 signaled to start,
273 the generator is running and supplies voltage to the inverter.
This is convenient to use for creating relevant notifications.
