Can Z-wave door locks be scheduled to lock at a certain time, regardless of the arm status of the system? For example - lock the front door every night at 8pm?
Unfortunately, there’s not a way to setup timed schedules for locks.
However, if you have arming schedules on your account, you could setup 2 rules that would function that way. Create an armed stay schedule for everyday at 8pm and a lock rule that locks the door when the system is armed at 8pm. That would get your door to lock automatically at 8pm. The potential downside is that your alarm system would also be armed at this time as well.
