A Logitech Harmony Hub works for this if you can still find one for a cheap price. Logitech has discontinued the hardware but continues to support the devices. Who knows when that will be, but I have two that I’m content to use until they stop working.
Here’s a recent discussion about remote controls that you might find of value.
Yeah, that’s why I say it’s a very distant future. DC does suffer power loss over distance (which is a big reason why we use AC for transmission), but within a building it would be possible to account for it. You’ll still need some AC plugs for high-powered appliances (vacuums, hair dryers, toasters).
What I’m suggesting isn’t a better solution unless a central AC/DC converter is significantly more efficient than the current AC adapters (which are typically ~80%). The concern I have is that is that the influx of wireless chargers is sending us in the opposite direction. They’re hideously inefficient.
Wow, that is a crazy story. Great work getting to where you are now.
