This should be easy to fix...
I have two thermostats, for two HVAC systems. One upstairs, the other downstairs. The T-stats both have humidity sensors. The built-in Thermostat tile doesn't display humidity. I don't want it to, that would be too crowded. But I do want to display that value on the dashboard. That works almost fine, using the Humidity template (a separate request would be for custom templates). However, the tile looks kinda like:
55%
Downstairs
(I made the device label "Downstairs" instead of "Honeywell T6 Pro Thermostat" which is the name).
Well it doesn't tell me what is 55% upstairs. Is that % battery remaining somewhere up there? I know what it is, since I put it there, but how would I expect my wife to have any idea what that is? If we could make a custom tile title.
In the meantime I have to use custom CSS (thanks @markus).
