Sonoff Basic R2/R3 DIY - How to convert

How to convert the board

Remove the thick [blue] wire taking mains directly from the input pin to the output pin Cut the board close to the relay pin, where the extra wire is soldered marked in the photo, this stops any mains reaching the relay. A Dremel with cutting tool works well, to remove any track or board at that location. Solder any wire [a short strand of Ethernet cable can be used] to the relay pin and output pin formerly used by the blue cable. Make a small groove in the side of the board to allow the wire to pass from underneath to above. Use a meter to test to see if there is any connection between input pins and output pins, there must be none In the App set Inching mode for the device to .5 seconds When you turn on the device the relay will close for .5 seconds and then open again. This simulates a simple push button in any circuit, completely isolate from the mains supply Convert to a button press [open garage or gate] wiring diagram
