Enigma2 anyone having a working configuration

Hi, I’m still new to HA and have not yet any great understanding of how to use different “functions” of it. Now I set out to try to implement my Satellite set top box (VU+ Duo) and also Sonos.
I have been able to implement both of those units in my configuration.yaml, so I can now see the entities. However I cannot get my head to understand how I now could use them in a smart way. For instance I would greatly appreciate having a way of starting my Sat box and change to a specific channel.
But at this stage, it is a to great step for my current knowledge! I have red as much as I have found, but still don’t really understand.
Anyone helpful HA ninja here, that have a good working configuration, where I can learn those things from.
Greatings!
