This piston turns a one button device in SmartThings into a button that can do 4 things, something different with each button press. This was made for a client that didn’t want to spend a huge amount of money on a device with 4 or more buttons so instead went for a cheap Xiaomi Aqara button. This was set up to change a Phillips Hue Lightstrip which was installed behind his telly, it cycles through the colours Blue, White, Red and Green. This could be modified to have less or more cycle options. Import code “ws820”.
