I have a lot of IoT devices that I am currently working on (read playing with). One of my biggest headaches is turning on the ones I need without climbing under my desk and plugging in a lot of wires. I looked at IoT controlled power switches but that is going to get very expensive very fast for a large number of distributed devices (really, a $20 power switch for a $5 micro computer?). Obviously once they are deployed in large numbers (~100 at a site) the desk climbing will no longer be an option.
I would also like to be able to turn them on (from fully off) from anywhere that there is internet. We can safely assume that most will turn on when power is restored.
Hopefully, someone has a better solution than mine.
