MultiPlus2 behaviour #5

Description

@klaute

Hi,

Thank you for sharing your implementation!

I‘m using your software in combination with a mp2 48/5000 in Germany and a pylontech us3000c.
And so far I can control the mp2.

Now to my questions. I’m facing some points I want to clarify:

  1. I consequently have to set the input / output power of the MP2 every second. Don’t know if this is right, if I’m not doing that the output or input power is set back to zero and after a while the MP2 get's into sleep.

  2. The MP2‘s main_i value shows always +-0.37A which is around +-85W (230V 50Hz) in idle (no power is set) mode. My cheap multimeter shows always 0.56A (expecting an issue of my measurement device) which is around 128 watts.

  3. If I send the sleep command to the MP2. it takes a while (minutes) before it goes into sleep. But the LEDs on the device don’t change. Also I still see the 0.56A on my multimeter (still expecting a measurement issue). How do i know if the MP2 is sleeping?

I have used your MP2 VEConfig settings from the repository's doc folder.
Please let me know if you want to see the screenshots.
