Bluetooth push buttons

Hello,
Is it possible to use bluetooth push buttons paired with a phone, in order to trigger automations from anywhere outside my home?

I’m thinking of a push button like the one shown in photo below which is supposed to trigger the camera’s phone for selfies.

It could be done with Tasker on an Android phone.

I understand tasker is an automation application, but can you use a bluetooth push button to trigger an automation?
At the moment I am using an iphone with ios shortcuts triggering my hass automations.
I would like to be able to trigger the ios shortcuts with a bluetooth button while riding my motorcycle.

It can probably be done with a flic button (flic.io) and the flic app on the iOS device, but I would enjoy a cheaper alternative

Best option I have tried so far is the flic buttons suggested by adepeuf.
They cannot trigger an ios shortcut, but they can post a webhook to ha which is just as good for me.
Flic buttons however are expensive, cannot handle a little rain, and require the flic app to be open on the phone for them to work.
Has anybody come across anything new that can communicate with HA?
