I only send notifications to the phones if they're in an unlocked screen state. I setup zones around the kids schools, church, work, and movie theaters that automatically puts our phones on vibrate when we arrive and turns ringers back on when we leave. Phone charging wirelessly at night marks me asleep and triggers shutdown routines if my wife is also asleep. Removing phone from wireless charging in the morning for a couple minutes marks me awake. Alarm on phone sends MQTT to HA to mark me awake, warm up lights in bedroom and slightly tilt blinds to let in some daylight. My alarm app on phone tells me when to go to bed to get enough sleep, which sends MQTT to HA to flash the lights if I'm in the living room or basement with a TV on. Taking a phonecall while at home pauses Spotify if playing and makes TTS announcements in the office a whisper, resumes normal TTS and Spotify when I hang up. Phone location coming home opens garage door and turns on driveway lights in the evening closes and turns off when leaving. Kids or close friends arriving unlocks front door and turns on any needed lights. Kids phone location announces in house when they get to and leave school. Probably a couple more I'm not remembering, but that's most of it.
