There appears something has caused the temperature background colors in ALL smartthings devices to become grey. I suspect this is related to a fix put in late Friday, as referenced here (follow the thread for some details):
several issues were possibly caused by this update (note: I know these exist on iOS – have not checked Android):
standardTile background colors ALL go to grey when using numbered values (as for a temperature device)
Humidity icon in thermostat multiAttributeTIle is now the SmartThings icon, instead of the small+large water droplet
Labels are being displayed in standardTiles when no label is defined (apparently displaying state.name)
Blank icons (or at least the space for an icon) is being displayed when no icon has been specified, forcing text to display higher/lower than it should appear in a tile
Because of some combination of the above, if you have a temperature device set as the default device for a room, the background will be grey instead of the color associated with the temperature
Hopefully someone can fix this sooner rather than later, since it has changed the UI (for the worse) across the entire portfolio of DTHs…
Hope they get a fix released soon. The iOS interface looks dreadful, and as above, colours have gone from temp/lux tiles.
Also, I now have to long press my sensor icons on the dashboard to have them open the detail screen; before, a quick press would open my sensor details.
Thanks for all the feedback. This is one of the threads I used to help track down and fix these issues over the weekend. You can read more about it here: Recent Tile Bugs (2.14.0)
Thanks guys. Dashboard display and behaviour back to normal (all apart from the black blob at top left of a tile where I’m being alerted to low battery). This black blob has been there for a few weeks now; I’m sure it used to be red with an exclamation mark.
