Hi,
many thanks for this great tool. For me, it works great for Power Values, but I don't get any information regarding the battery.
I get following information from the inverter?

Device Class:     Battery Inverter
Device Type:      Sunny Boy Storage 3.7
Software Version: 03.12.33.R

But for Battery Charge Status or general Battery Info I get just the Packet Status 21 which I understand means "command not supported".

Packet status: 21
getBatteryChargeStatus returned an error: 21
Packet status: 21
getBatteryInfo returned an error: 21

I checked the addresses of the return values in the diff description of the sunny portal, and they seem to be the same, but the command may be different. Are the commands somewhere available? I haven't found on the web so far.

I also get odd response for getSpotDCPower and getSpotDCVoltage (I dont see if this comes from Sunny Boy Storage 3.7 or Sunny Tripower 10.0)

Packet status: 21
getSpotDCPower returned an error: 21
Packet status: 21
getSpotDCVoltage returned an error: 21

I do have basic skills in programming and may support here, but I am not keen enough to just loop commands to the Inverter for now. I am scared I screw something up.
