For the dryer think even simpler: get a Esp32 with a SW-420 vibration sensor, stick it on top of the machine somewhere, and look for vibrations. Since most dryers don’t have cycles, it’s really easy to detect if they’re running or not. There’s even a potentiometer on the SW-420 so you can adjust the sensitivity without reprogramming the ESP32. |
