When you get a vibration sensor and tape it to your old, dirty washing machine and hook it up to an #ESP32 #S2Mini (shown in a 3D case I whipped up).... you create your own "Smart" Washer.
You don't even care how absolutely filthy it is behind the ancient device cuz now you're getting #Pushover notifications when the wash is done.
The code wasn't even that difficult, which was a bonus. Just had to find a spot on the machine that jiggled enough during all the cycles (fill, wash, spin, drain) but didn't get triggered by the dryer next to it, then whip up a little "vibrate this much for this long it must be on, okay it's been still for this long it must be off. Wash is done!" function.
I am addicted to these things and have more random stuff I ordered from AliExpress when drunk on the way as well.
