Battery Levels in Vera with NYCE sensors

I had three NYCE door/window sensors batteries go dead while they were still showing 80% in vera. I checked the “BatteryDate” variable for the sensors and ran it through the epoch converter and it showed a recent date/time of within minutes of the current time.
I currently have one sensor reporting 80% battery that is still working but Vera is sending a low battery alert for the device. I’ve also had a similar issue with the NYCE tilt sensor.
After changing the battery on the devices that had the dead batteries they show 100%. Is there something wrong with the devices or is there an issue with the battery level in Vera?

I added some log entries. The only thing I see is that sl_BatteryAlarm went from 0 to 10.
What does this variable represent?

Still seeing battery level alerts being reported when battery level is still showing 80%. It’s a different sensor this time.

NYCE support is saying that this is an issue with how Vera is handling the battery voltage. I’m assuming that with the Ezlo product launched this will not get fixed in the Vera controller.
