It’s fairly straightforward with Tasker and SharpTools if you decide to go that route.
I’ll post a video when it’s done uploading, but the gist of it is:
- Create a new Tasker Event profile for Phone → Ringing
- Create a For loop that loops through the items
1:6
(or however many times you want to toggle the light) - In the loop add a Plugin → SharpTools: A Thing configured to
toggle
your desired light - In the loop add a Wait for 1 second
(or however quickly you want the light to toggle)
