I just bought some velux skylights, and they come with co2 sensors and temp sensors. Because mushroom entity cards wont let me do custom secondary information, i have to use mushroom template cards.
the hangup is that with the mushroom entity cards, I get the cool icon changes for when the skylight is opening, or when its open, vs closed - however with mushroom template cards you have to pick an icon and its color and those remain static regardless of the actual status of the skylight.
tl;dr: how do i get the mushroom template card icons to behave like the mushroom entity cards? Or, is it possible to use templates inside of mushroom entity cards to get that juicy sensor data?
I don’t think you can. Mushroom cards are designed to be simple.
If you want to do things like that, either use the template card (as you have mentioned) or use custom:button-card.
I need up creating a bunch of ‘standard’ custom:button-cards within decluttering-card for this reason and the only mushroom card I use is the chip card now.
