I personally prefer to stick with the better looking integrated Thermostat card. Hope they can open this up a bit to add some extra features like humidity display.
I came her to post the same just to realize this has already been raised.
Especially that if you click on the 3 dots on the thermostat… you do get the humidity.
First post, long time lurker - that said I came here looking for this request, I would like to add my weight to this as we live in a marine environment so high humidity is always taken into consideration, from when to put the laundry out or hang it indoors this feature would be super useful
