iOS and/or Android notifications via ESPHome.

Please describe your use case for this integration and alternatives you've tried:

I have successfully paired an ESP32 to my iPhone and received text messages and call info via the serial monitor in Arduino IDE. I have posted details here. I don't know how to code so I cannot modify the sketch to serve my objective.

I would like to be able to leave my phone unattended for a period of time and have a means by which to receive passive notification of there being missed calls or messages without having to pick up my phone ...like BlackBerries used to do with their flashing LEDs.

If ESPHome were to pair to my iPhone's ANCS and flash an LED via GPIO switch when a call was missed, I could rely upon this LED and break the habit of checking my phone unnecessarily (a habit that causes many people undue distraction). If I walk into my room after leaving my phone behind for an hour or two, I'll know whether I've missed a call or text because the LED will be blinking. If it isn't blinking, I can continue to leave my phone alone and remain focused on other things.

Furthermore, if the content of a text message could be sent to HA, there are surely users who would benefit from the message being read to them TTS over Sonos. Or similarly, if a certain person (say, a family member) calls while I don't want to be bothered, then I can have an HA automation notify me in specific, subtle ways. Yes, we can assign ringtones on our phones, but the idea is to create a buffer between the phone and the user, to mitigate habitual use of the phone, and to integrate with HA for uses that I haven't yet fully determined.

Also, the usage data could be tracked, to chart the amount of call/SMS activity over a period of time, in case there are people who would like stats on their texts, etc.

Additional context

I don't know all the ways in which this would be useful for others, but surely there are things I have not thought of. Maybe someone has an elderly parent and the shortcuts/automations built into iOS are not sufficient to help them to manage their parent's life. But if that parent had HA at their home, and an ESP was paired to their iPhone, specific automations could be called by people (caregivers, etc) via text message, even if those people didn't have HA login creds. That's just one example.
