Recently I find there are frequent false alarms triggered when my wife drives back and opens the garage using the remote. ST is still armed because the presence sensor is not detected yet. So the opened garage door immediately triggers an intrusion alert. The presence sensor is detected the next minute.
Then I learned SHM does not support entry delay right now. Did some search here, find several ways. Daisy chain requires lots of work to setup (virtual devices, custom codes). Smart Alarm app does support entry/exit delay, but not compatible to ST’s Smart Home Monitor. The last method using CoRE is the simplest and can work together w/ SHM. CoRE is very powerful, but for normal users we just need the least things to get work done.
Inspired by @RobinWinbournepost, I simplify it to only use 1 virtual contact sensor. Setup SHM security to monitor this VC and exclude all doors that need entry delay. Then use SHM to trigger intrusion alert and siren.
Here is the piston for the alarm delay. I set the delay to 90sec. It will only run in armed state of SHM.
One recommendation for your piston… the 10 minute delay before closing the simulated contact sensor is unnecessary. Closing the sensor does not turn off the alarm, instead you should set the ‘alert duration’ in SHM under sirens.
You just need the contact to open for a few seconds and then close again.
Personally I use CoRE to handle everything (sirens / lights / texts / machine guns / self destruct / reset)… the only reason I recommended linking a simulated contact sensor to SHM (in the post you linked to above) was for those users that wanted to use Scout.
I’m not sure but you might find that your current piston turns the siren on for 5 minutes, then again 5 minutes later for another 5 minutes… depends if SHM looks for ‘changes’ or ‘changes to open’, I’ve never tested that one!
A simple way to solve all these delay issues is if Yale had a device handler that could change the Smarthings mode when it is locked. IE. If you locked the door from the outside then it would arm the alarm to Away, if you pressed the button on the inside then it would arm it to home. This would be a simple Local control solution that solved many problems and would not need to have to worry about a delay with Entry/ Exit sensor. If they added a secret silent alarm distress code too then everything would be perfect and done very simply.
I have a Fire HD tablet and LANnouncer. I would like it to play an old fashion steady tone when entering to let the user know they have activated the alarm and it needs to be unset from the tablet(action tiles) before the siren sounds. Is there anything built in to LANnouncer that would be similar to this? I was going to create a piston like you did but have another settting for LANnouncer.
I guess I could also make a continuous beep when exiting to act similar to the entry delay to mimic an actual alarm system. It looks like a custom audio files is my only option. Any thoughts?
