This app was designed for the Zooz MultiRelay (ZEN16).
REMOVAL OF EMERGENCY REVERSAL SYSTEM OR EYES CAN RESULT IN SERIOUS INJURY OR DEATH IF THE DOOR IS UNABLE TO REVERSE OR STOP IN THE CASE OF AN OBSTRUCTION.
You should look into your local safety standards of automatic garage door openers. United States Example
It's probably a good idea to sound a siren/chime while the garage door is moving and you can use the opening/closing and open/closed events of the child door device as triggers to do that.
The SmartApp automatically creates a child garage door device for each garage door you setup in the app and you can use it to see the state of the door and open/close it.
When you use the child device’s open/close commands it will put the device into the corresponding opening/closing state, turn on the relay switch, turn off the relay switch after the delay (if applicable), and once the door stops moving it sets the door state to the contact sensor’s state.
If the contact sensor changes and the child device didn't initiate the change then it sets the door state to the corresponding opening/closing state and once the door stops moving it sets the door state to the contact sensor's state.
If the switch turns on and the child device didn't initiate the change then it sets the door state to the corresponding opening/closing state, turns off the switch after the delay (if applicable), and once the door stops moving it sets the door state to the contact sensor's state.
If you want to use a siren/chime to play a sound while the door is moving you can use the opening/closing events of the child device for the start/stop triggers. The "Garage Door Operating Delay" setting allows you to delay turning on the relay to ensure that the siren/chime starts playing before the door starts moving.
