Pairing issues, the hub firmware has some bugs, it happens sometimes. I’ve seen this reported 2 times in the past week with Kiwkset locks, don’t know if it’s related to the Schlage MSR firmware bug (@nastevens ), exclude and repair is the best fix for correct the MSR.
If you’re on the latest code, try this, it will force the lock to resend the MSR. Click on the gear icon on the top right to get to the device configuration page. Then click on Done. Now click on Refresh (watch your Live Logs), it will force a MSR request from the lock. If that fixes it great, otherwise you’ll have to exclude and re pair it.
