{"NAME":"Shelly RGBW2","GPIO":[0,0,52,0,40,255,0,0,37,17,39,38,0],"FLAG":0,"BASE":18}

When using AC wiring and the supplied AC to DC adapter: To make use of the Input clamp of the device you need to set GPIO5 as Button2n.

Due to the way the adapter sends out pulses to the GPIO you might have to solder a small 2.2 uF capacitor to the adapter to stabilize the pulse and avoid erratic switching.
