[APP][Pro] Power by the Hour [Feature Requests]

Requested by @LecramR and @Daniel_S : add Victron as battery device.

Source code Victron app: GitHub - ricott/homey-com.victronenergy

@LecramR @Daniel_S I need to know from you the capability names. Please go to Homey Developer Tools
And select your battery device. Create a screen shot of the capabilities, similar to this one of Sessy:

Please tell me which one represents battery charge (0-100%), and which one is the power flowing in/out of the battery. Also I need to know if charging is a positive or negative number.
