How can I switch mains-powered loads wirelessly, with low cost and low power consumption

Your question is a bit ambiguous (or perhaps I'm just thick), and it's also leaning toward being off-topic as a "shopping request". But what I got from reading your Q was that you're looking ...

How can I switch mains-powered loads wirelessly, with low cost and low power consumption

I've used SonOff switches quite extensively, very reliable, you can reprogram with your own firmware (e.g. Tasmota) and have a local manual override button. They do require both live and neutral ...

How to make a raspberry pi "hot unpluggable"

You can't make the entire RPi "hot unpluggable" by dealing only with the SD card. You're (presumably) using the ext4 filesystem; this helps prevent corruption on your SD card because it's a ...

Will accidentally powering a pi with more than 5V break it?

The parts are given a voltage rating by the manufacturer that will work with all of that particular processor, they also have a guard band to insure that. The process used to make the processors have ...
