I have a garden that I enjoy, but after years of trial I've learned to only plant hardy native plants and wild flowers because I have a black thumb for vegetables. My main issue is a lack of patience -- I don't want to go out to water everything or monitor if things are getting as much sunlight as I thought they would. But for the last couple years I'd been considering setting up a raspberry pi, some moisture sensors and some kind of drip system as a fun summer project to add on top of my flower garden, so that'd be a journey for me.
It's a cool toy, but in the end you're going to be spending more time and money maintaining and troubleshooting this contraption than you would have by just touching grass and getting your hands dirty.
