Wanted to swing in here with a disability perspective if that's okay - while it's not exactly off-grid living, a lot of people with disabilities have homes that are optimized for accessibility which can be confusing for visitors! We also tend to need stuff to be done a specific way which, while not technology related, is really important and can add a learning curve.

Some examples off the top of my head: Computers might have screen readers, trackballs, alternative keyboards, accessible buttons, etc. Stuff like light switches, thermostats, door handles might be modified to suit limited mobility. Appliances like microwaves or coffee makers can be voice activated or have larger/more grippable buttons (which aren't always intuitive in today's touch-screen world).

The smallest personal example I can think of would be cooking with food allergies, which I know is not an unusual thing these days, but a lot of my friends are still confused about how cross contamination works, e.g. if you use a butter knife for butter you can use it to spread that butter on your toast but you cannot dip it in the jar of jam, because that would contaminate the jam with dairy and gluten. Or, a personal example, I was teaching my partner how make a mug cake using only one tablespoon measurer and explained that you must add the ingredients in a specific order (such as flour last) or you'd be successively contaminating each ingredient for my little brother.

My household also just does a lot of things very specifically for our needs, like we vacuum instead of sweep because of my allergies, and I go around and shut curtains in various rooms throughout the day because our AC isn't strong and we try to use it as little as possible. I wash laundry on cold to protect the fabric but dry it on hot to kill the dust mites. We use soap bars instead of soap dispensers for hand washing which often throws off guests, and I keep the liquid dish soap in a hair conditioner pump bottle (it's what I had, can't afford a fancy decorative one, also it works really well anyway) which also throws off guests XD And the left side of the sink is always clear and we do not put dirty dishes in there, partly so we can refill water bottles without them touching dirty dishes and partly to accommodate my partner's autism.

My balcony garden has a weird system of jars underneath the plant stands to catch any water that drains out of the pots after I water them, plus there's currently a bunch of soup pots and random containers on the roof to catch rainwater. There's no spigot on my balcony and I don't have the energy to go back and forth a bunch for water XD And my "watering can" is an old vinegar jug.

Not sure if any of that is helpful for what you're looking for, just some thoughts c:
