Hey everyone.
Is it possible to have a door lock when a multi sensor is closed? I saw a post about it but it was almost 6 months old.
Right now my front door unlocks when I arrive home but I want it to lock automatically when I shut the door.
Hi Steve,
There is an app somebody shared in the IDE SmartApps section that can lock a door after n minutes. I modified it to be aware of a contact sensor attached to the same door. The lock will not lock if the door is open. If somebody locks it while open, it will automatically unlock it.
I’m not a developer, but here is the modified code:
/**

I’m slowly learning how to code (mainly by looking at the SmartApp examples). I love the IDE simulator and the debug/logs console.
This looks great. I will give it a try. Thank you for posting the modified code. I plan to start trying some coding myself at some point.
