It took a few days but 1 of the 2 Wink sensors has stopped working. Nothing appeared in the logs when the door was opened/closed a few times. The battery level is 86% which was last updated this morning. There was some open/close events yesterday but that's it.
Front Door battery is 86%
I guess since the other door/window sensor is still working I can't say it's a driver issue.. only that both sensors were working great with Wink.
Sorry there's nothing else to really go on here.
FWIW here's the device details from both:
