Spotmarket-Switcher dynamic prices integration

[christian1980nrw]

Hey developers!
Great project. One of your users told me that he is using my dynamic price controlling project Spotmarket-Switcher together with SolPipLog. He had success with the integration but unfortunately he is not a programmer and i dont have a SolPipLog system.
He is using this commands:
Solpiplog switching to external power
echo "Turning solpiplog uti/sol (Netz)."
mosquitto_pub -u emonpi -h localhost -t solpiplog/pip/status/set -m uti

Solpiplog switching to solar-battery
echo "Turning solpiplog SBU (Solar-Batterie-Netz)."
mosquitto_pub -u emonpi -h localhost -t solpiplog/pip/status/set -m sbu

I have some questions:
Whats the command to read out the SOC of the battery?
Is it possible to charge the battery for example up to 50% if these commands are executed or will it always be 100% or will it not charge and turn only the battery on and off?
Are these commands working "out of the box" or are some preparations necessary that should be documented if i offer SolPipLog support at the Spotmarket-Switcher?

Thanks
Christian
