Change state of a helper-Switch depending on the entries of a calendar

[plucky cairn]

What I have:

• local HA Calendar with 2 possible entries or none per day ,

What I need

• entry A exists -> switch A on, else off
• entry B exists -> switch B on, else off
• change in the calender -> check for entries, apply above logic

I tried automations, scripts and using google to find a solution but no luck
