someone can suggest an app that can be controlled from api / rest and allows for example to temporarily set the volume to maximum and playing a notice or sound, to make me find the phone while I’m at home?
Perhaps this is possible on Android with tasker, but on iphone?
Perhaps an IFTTT rule might work? I’ve never tried to do precisely that however so can’t be sure if it’s possible.
Having a quick look and it should be doable. There are plenty of people using Alexa to have their phone ring. But the phone call channel is US only so might not work for you if you aren’t in the US.
There are at least a couple other implementations of this that I’ve seen out there also.
