My opinion (FWIW): Ignore the battery %, and use a different method to track the availability of the device(s). In my experience, battery levels are not tracked consistently across devices, and are affected by type of battery inserted, etc. They have never seemed reliable to me. Don't get me wrong; I'd LOVE to be able to track battery %s and just get notified when one of them drops to 10%...
Two other options that I have seen many others use:
- Use an app to track the availability of battery-based devices, like Device Activity Check. You can set it to notify you when devices stop communicating with the hub.
- Plan on replacing batteries every x months, based on use of the device.
I personally use option 1. YMMV.
