I know about the iTead Sonoff, and the Sonoff With temperature and humidity, but these operate on 110-240v AC. Does anyone know similar but for controlling 12v DC?
Currently I have a raspberry pi, that among other things, has a dht22 sensor and a mosfet switch where across various topics based on temp reported the mosfet switch is told to turn on two fans that cool my network stack.
While working, it looks a little ugly, and the scripts on the pi sometimes don’t come back up upon restart.
Now i could, with a 12v - 5v volt converted, mosfet switch, d1 mini, dht22 build one with the homie framework, but I’m not great at getting these things in enclosures in a nice neat package…hence my question.
