I read a post that some of these are showing a battery alarm falsely and Wink was aware of the issue and would be issuing a firmware update. Is there anyway to firmware update these without connecting to wink hub? If not, anyone know if removing the sensor from the network will also reset it in this case so it can be added to a wink hub to updated and returned to the A+? I have a wink hub laying around and some sensors in route. Want to make sure they can be updated in future. Thanks!
