I just gave v0.81 a try and added an instance of the new thermostat glance card to my lovelace config:
- id: 81419d30758741938645c8f08131ea95 # Automatically created id
type: thermostat
entity: climate.danfoss_office_heating_1
The referenced thermostat is a Danfoss 014G0013 Z-Wave thermostat.
But instead of the new thermostat card, nothing appears on the screen, not even one of those red error cards.
Lovelace still seems to generate “something”, because when I remove the card definition, the whole page layout changes from 3 columns to 2.
Also, it looks like with the included card definition, the column where the thermostat card would render is shifted a few pixels downwards - looking like an invisible card with only a few pixels height is “displayed”.
I’m using the broadlink climate component with this and my ‘fan’ mode is missing. In 0.81.0 it had an invisible ‘fan’ button, but with 0.81.1 it disappeared completely. I see a lot of pictures of other people’s cards have the fan function present.
I’m on 0.81.2 since shortly after it was released. Nothing changed for me.
I see no errors on the console or home-assistant.log.
Here’s the screen shot of one of my thermostats:
As I said, it should be fixed in 0.81.3 only thing that isn’t fixed in 0.81.3 is the theme for the card. 0.82 will fix it so you can change the background
