This image goes to doesn’t … Continue reading Japanese wiring isn’t automation friendly.
Dr ZZs once made a video about ghost switching. When long leads pickup signals and the esp8266 (sonoff) interprets them as inputs. Not quite the case. Although the cases for the multi sensors are a little ghostly. (Car air fresheners containers from Daiso) My light was going on and off randomly in a room that was not occupied. His happened in consistently at night which … Continue reading USB ghost switching

Now I know not to expect much especially when I found a dual 2.1/1 amp charger for 103JPY. I figured I’d give them a try, as with shipping they would … Continue reading My first hiccup with AliExpress
