SmartTiles V5.3 introduces a new feature: Event History. This view shows 24 hour activity feed of all devices that are associated with a SmartTiles instance.
This feature is enabled by default. You may turn it off at SmartTiles app preferences.
The number of loaded events is limited to 200 per physical device per 24 hours. If you have a device that generates a lot of noise events, Event History will not display more than the most recent 200 events.
This feature was created in collaboration with @jazzyjayx. Thank you Jay!
The other important feature is the ability to enter Custom CSS via app preferences. This allows customizations of SmartTiles that are installed via Install Now option. This is also advantageous for manual installations, since SmartApp code can be updated without worrying about the custom CSS block.
