The main thing to understand with the Thermostat tile is that it is a deception that uses layered controls.
One the bottom layer is the standard thermostat tile.
The CSS manipulates the components of this standard tile.
On the top layer is the Tile Builder Thermostat Tile that has transparency and passes clicks to the standard Thermostat Tile beneath.
The CSS that hides the title for all tiles is the 3rd line....
FYI everyone. I reported a bug where incorrect endpoint content is displayed for the third time. If it is affecting you please give it a like or comment.
I had this the other day.
I had a Remote Builder tile displaying a number of different sensors.
It became too big so I decided to split into 2 separate tiles.
When I loaded it into a dashboard window the original tile was shown in both the old and the new tile.
Very weird.
I decided to put the new tile into Tile Builder as opposed to Remote Builder which resolved the issue.
I just released an important update to SmartGrid which allows it to support embedded endpoints, with Tile Builder endpoints being the ones I mainly had in mind.
