I am using Homey and the app Heimdall as a complete security system. So far, it is working perfectly. What I am missing, is some way of playing an ongoing alarm on my iPhone that has to be dismissed before it stops. It should also override if I have silenced my phone during the night. Any ideas?
In short: not possible with a (non-jailbroken) iPhone.
This can be a solution:
Then I can tag the Woopla phone number as favorite that will call me even though the phone is silenced.
I am not very familiar with IFTTT. How do I configure a phone call when my flow “Alarm tripped” is running?
