Any luck that Hubitat will fix the battery level readout in the app. Even with brand new Lithium batteries, or with 100 % fully charged rechargeable batteries, the readings in the app are completely wrong. Its a bit annoying because we cant rely on these numbers.

This is not a Hubitat problem; it's just telling you what the devices report.
