Adding additional sensors/support for battery inverter

[HartmutHartmann]

Added the integration to HA yesterday, seems to work well so far.

Now I would like to add more sensors, for example to see dc power per string.
Additionally I do have a battery inverter which I would like to connect as well. The integration seems to connect initially, but reports 'Failed to set up' as soon as the inverter is added(didn't try logger yet). I also tried the 'test.py' which connects to both inverters just fine and reports correct data.

Unfortunately I have no experience writing Python or HA integrations. Any hints on which parts of the code need to be edited would be appreciated.

Edit: restarted Homeassistant, now the battery inverter seems to be fine, no more error...

• sma_speedwire.py: library to commulicate with SMA inverter
  • COMMAND_LIST: extend with commands to read from inverter, check https://github.com/Rincewind76/SMAInverter
  • self.sensors: extend list of sensors
  • def _fetch(self, command): extend parser to parser added command responses and fill self.sensors
  • def update(self): call added command
• sensor.py: HA sensor
  • def __init__(self, coordinator, device, sensor): extend wit your added sensors. Check here https://developers.home-assistant.io/docs/core/entity/sensor/
