I'm not claiming they are the best solution. Just that they can be useful. Smart thermostat, you don't have to get up to change the temp, or deal with any small buttons/controls. Smart light bulbs. Again, don't have to get to turn the lights on or off. They're are a variety of ways to do this without smart bulbs though.

The list is gonna be similar reasons for most of them. If it's difficult to get around, anything you can do without having to move can be helpful.
