The stock DTH doesn’t provide any of those features. I was referring to Aeon Labs Multifunction Siren DTH you included a link to in your first post.
To make it beep you need to select it as an audio device and use beep as the custom message. The device settings below will provide the most reliable beep.
- Beep Sound: 3
- Beep Volume: 1
- Beep Repeat: 1
- Length of Beep: 100
- Play Beep Schedule for Beep Command: OFF
- Play Beep Schedule Before Sounding Alarm: OFF
I’m assuming you’re using SHM so if you’re selecting the siren as an alarm, you shouldn’t be experiencing problems with it not turning on or shutting off. Most sirens will have a random delay when turned on from SHM, but the delay shouldn’t be too bad when your turning it on manually from the Mobile App.
That being said, for about a week, I’ve been having tons of SmartThings automations fail.
If the device is near the hub and you press the action button multiple times during the pairing process, it should pair securely, but some users have been unable to get it to pair securely.
If you enable debug logging in the device settings, you should see a message in Live Logging that says whether or not Secure Commands are enabled. You should be able to force it to display that message by going into the device settings from the mobile app and tapping the Done button.
If you have the doorbell volume set to 10 you should be able to hear it on another floor and/or behind closed doors, but it’s not a substitute for a siren. If you’re using it for notifications I recommend adding some type of sound to the beginning of your sound tracks so that it gets your attension before the message starts.
Using the Aeon Labs Aeotec Doorbel DTH, you can select it as an audio device and play the tracks by number.
If the device isn’t paired securely, you’ll see an additional 1-2 second delay.
If you’re using SHM or Speaker Notify with Sound and you’ve selected it as an audio device instead of an Alarm or Switch, you’ll see an additional delay because the track number gets sent to Amazon’s TTS service before it gets sent to the DTH. If you select it as an Alarm or Switch or you’re using the SmartApp CoRE to play the track by number, it won’t have to go through Amazon first and the delay souldn’t be as bad.
