I have a Yale smartlock purchased in March, 2019. It has a touch-pad and keys. After it worked fine for over a year, it started to fail. When it fails, the keypad doesn’t work and the lock doesn’t respond to Smartthings commands, although it still reports back status to the hub (when I lock it manually, for example)
I’ve changed the batteries multiple times and have seen this problem come and go. Any advice is appreciated. I’m going to look in to firmware but I’m at a loss otherwise.
I did the factory reset successfully. However, contrary to Yale’s advice, it screwed up the SmartThings device configuration. I had to do the reset again after removing the device in my ST configuration. So far, so good. The keypad is functioning and the ST commands are working.
I will monitor. If it screws up again, it may take a few days.
