At time mark 2-3 seconds there is a great view of the poster’s dashboard, and at the bottom there is a group marked Battery Minder that shows the current status (good, ok, replace now) for various devices.
Looking through the Community site, in the SmartThings App and the IDE I can’t find anything like this. @Ben, did you folks accidentally preview something new or could you provide a link to the app as I can think of a number of uses for this ability to summarize window/door sensor states AND I’d love to be able to see my battery stats at a glance though I am doing that with @625alex’s Action4 dashboard as well.
