    Oh right @Njord insisted I tell you, fedi, about this button. It's a big orange button (AC remote for scale) that toggles an extension cord's power on/off when pushed

    So far so boring right? Well it had been acting up a bit so we opened it up to change the battery and... no battery?

    It apparently uses the mechanical force of pushing the button (it requires a bit of a push!) to trigger a piezoelectric charge which is apparently enough to send a wireless signal to the receiver

    Neat!

    @eniko @Njord My previous workplace had a battery-free wireless doorbell - this must be how that worked too. Not as cool as a big friendly button, though!

      I got light switches like that in my house for nearly ten years. Sometimes you have to push them several times if you haven't used them in a while, probably to get enough piezo charge for a signal.

          @eniko @Njord our front door bell is like that, it’s nice not having to wonder about missing a delivery because the battery died, it can’t now. Love tech that makes life simpler not more complicated

          I got fed up with batteries in door bell button and the "bell" and unreliability (433 MHz).
          Eventually I found a real wired pushbutton and BingBong inside box, though that used batteries. So I added a transformer to 8V AC at the fuse box, because the bing-bong real solenoid doesn't care about AC or DC. The bulb in the door bell button is across the switch, so in series & glows orange, thus long life.

          1950s technology, but 100% reliable.

          No spying to Amazon.

                @eniko @Njord BTW the Brazilian product page says there's a fuse which can trip if current exceeds 10 A, but the fuse should be resettable

                  We had kinda the opposite in our last house. The button-push was wired to a battery-powered bell box, but the builders had put the bell and the battery directly above a radiator, which meant that we had to change the batteries every six weeks or so, because batteries don't like heat. We eventually gave up on it and installed something mains-powered.

                      I've added mains and/or rechargeable to many battery things starting with a VFD calculator.

                      Now all the non-heating/cooking stuff is on a Solar & Grid charged UPS. 12 main panels and about 14 kWh of LiFePO4 batteries.
                      No more annual PC UPS battery replacement.

                          (via the menu you can change region to UK - while selecting Benelux doesn't seem to work)

                            Enocean is a conglomerate of smarthome appliances purely designed with energy harvesting. No changing batterys ever.

                            Unfortunately it is rather expensive and more difficult to integrate.

                                You can receive free electrons off of glucose through enzymatic breakdown similar than the body does - although the body stores it chemically in ATP or others.

                                It is however currently no longterm solution since the enzymes break down over time.
