I can’t swear to it but I really thought I was on the stock Edge drivers (although I have Philh30’ installed). Checking after getting these messages and my locks have changed to Philh30s driver. I could be wrong on that though.
Phil’s original Z-Wave lock driver had the issue that the stock driver has where it periodically resets all the codes to 'Code XX". He provided a fix for that in the beta driver.
I also saw that behavior on both the stock and Phil’s original driver. Plus the beta has the unlockCodeName exposed which can be used as a trigger in Routines.
