Door lock event failing to lock door

[dibble9012]

I'm having an issue with an automatic door lock event. I have it set up as the first attachment. The problem is, I think network latency is causing the door contact sensor to become closed before the door becomes unlocked. So sometimes my door does not automatically lock. I thought about putting an AND option in and just reversing the first section, but then the door sometimes locks while the door is left open. Any ideas? Thanks!

I would change the first trigger to "If the front door has been closed for exactly 15 seconds" and "the door is not locked".
