Generally, black is ground, and red is 5V power, and there is a third wire that connects to the data pin. On OpenSprinkler’s sensor port, the right pin is ground, left pin is data, and you need to solder a wire from the pinout area to get 5V (it’s marked VIN). It should work this way.

We are currently away till Monday July 21. Orders placed during this time will be shipped on Tuesday July 22. Thank you for your understanding!
