I am considering making an arduino shield for use as a siren relay panel. I need to know 2 things before getting started though, hoping someone can give input…
Is the smartthings arduino shield whitelisted for local processing?
Can I set up the shield as a siren in smart home monitoring so that it will be sent a start and a stop signal when there is an intrusion? Lights seem to only be sent start signals when there is an intrusion so that wont work
If local processing is one of your major requirements this project is likely to be a non-starter.
I believe the new “smart lights” lighting wizard is the only app that will run locally. No other smartapps will run locally, that includes smartthings-created smartapps like the smart home monitor.
Can I ask why arduino shield? Are you trying to tie into an existing alarm panel or just create a new alarm/siren from scratch?

The Shield joins as an empty template Device Type. Therefore anything you build with it needs a Custom Handler and it will be a very long time before SmartThings allows us to load custom Device Type Handlers locally.
Is there a way to have smart home monitor turn off the siren when the house has been disarmed / intrusion dismissed? I thought about doing something like that (that’s actually what I tested to see if shm would work offline) but I need it to turn back off as well.
One option I was thinking of was gutting a z wave siren and using it to trigger a relay.
Ah ok, that works but you still do need to manually intervene - I am hoping to have something that will turn off automatically after x minutes like the siren seems to be configured to do - I dont want to end up getting a fine from bylaw for noise in addition to getting robbed haha
Smart home monitor has a timer built in for the siren - does that not work? It doesnt require that the house be disarmed or the intrusion be dismissed. Or at least thats how its represented, I havent tested it.
