Return yourself to the 1990s: Keep your mobile phone plugged in at all times when at home. Make it like a home phone line - turn on phone / texting notifs and disable all else. If you want to / need to check it, force yourself to walk to it to see that text or look something up. Print out things you need (like recipes, etc). Similarly, dock your laptop, and keep it docked when at home.
Not 100% possible, but it is a way to try and reduce the temptation to always check.
