A controller to read out and send commands to a SMA Sunny Island battery inverter. SUNNY ISLAND 4.4M / 6.0H / 8.0H
This code was used in a home built Home Energy Management System (HEMS), to include a battery into a smart home. You can read more about it in my blog post: How I built a HEMS with solar, a battery and a charge station (in Python)
print readSMAValues() # To print all values
print readSMAValues('ChaState') # To read a single value, in this case the State of Charge (SoC)changePowerOfTheInverter(1000) # To discharge the battery with 1000 Watt (1 kW)
changePowerOfTheInverter(-2000) # To charge the battery with 2000 Watt (2 kW)The code within this repository comes with no guarantee, the use of this code is your responsibility.
