I ended up building a nice charging station right near the entrance. It has storage for keys, wallet, and other things to grab when heading out. It has an abundance of wired and wireless chargers for all devices.
Then I got a dumb (but nice) alarm clock for the bedroom.
Then I noticed that a common reason to pick up the phone is to check the calendar. I ended up hanging a monitor on the wall, displaying the family month/agenda calendars. It’s read only, but it prevents a lot of device checking.
Cannot recommend enough restructuring physical reality to not have device on your person at home. It also helps the kids to put theirs away and learn good habits.
And great insight about the calendar. That's the #1 reason why I keep my phone near me (thereby facilitating all the unwanted behaviors)
A half hour before the alarm goes off, it slowly gets brighter which I find simulates the sun rising enough to be a more pleasant waking experience. Plus I set the alarm sound itself to bird chirps, starting with 1 or 2 birds and growing into a whole chorus (I'm usually up before then)
I hear the ancients had their own crude technology for this:
