Not in the bridge API the binding uses right now. There’s doorsensorBatteryCritical in the web API but that only tells you when battery is critical, not the actual battery level.
The Bridge-API does offer a batteryChargeState → you could file an feature request on github - or the binding-author reads this and updates the binding. but AFAIR the binding is orphaned and not updated for quite a while?
Posting also into this thread - I’m working on support for Web API, you can try latest verson here:
