I’ve made a temporary fix and started my own discussion about some of the technical points here:

Yale Keyless Lock Battery 10% Bug Fix

It seems there’s a bug with the UK Yale Keyless Lock. Using the built-in device handler or the Universal Enhanced handler the lock reports 10% battery from new. (I haven’t seen this change but I’ve only owned it for a couple of months) I’ve done some debugging and it appears the Yale Keyless is sending “00 80 03 0A” 0A is 10 in Hex. So the lock is incorrectly sending its battery level as 10. The only time I can get it to send this data is when it’s first paired with the hub. Looking at the device attribute history the battery level hasn’t logged any changes, so it looks like the battery level never gets resent. I’ve had a play around with the ST Zwave lock handler and a modified version can be found here: https://raw.githubusercontent.com/TmpR/yaleKeylessLock/master/deviceHandler.g…
