The Battery Tile is one of my favorites!
I do have a question about it: How often is the battery life interrogated/updated?
I’m trying to track down possibilities for poor battery life in my Schlage lock. It’s been a concern for a while, but a recent update to Hubitat’s Schlage driver seemed to cure it. Now I’m experiencing lousy life again. I suppose it could even be my hardware.
Glad to hear you’re enjoying the battery tile!
From the SharpTools side of things, it’s all event driven. When the tile is added, we setup a subscription to the battery attribute of the device and then whenever the hub sees a battery update, it pushes the update to SharpTools.
The real question would likely lie with the device / device driver. Most battery powered devices periodically report their battery life. Some also report the battery whenever the device is actuated (eg. locked/unlocked).
