When I check my Sensibo device list I see all my sensibo devices, however the most important piece of information is omitted. When looking at this list I feel the most important information is the current state. I want to see if my air conditioners are turned on. Currently I need to go into every device to see if they running. Where as a column would be great to see if they are currently on.
Exactly opposite - the purpose of auto entities card is to display anything, you define with a filter. So if your filter is set up right, the card will automatically add new devices and also removed devices will go away automatically.
You can use wildcards with it. Something like this:
include:
- entity_id: "*sensibo*"
would automatically display any sensibo device available in your system.
