A Smart Upgrade for German Shutters Belts. You can operate your shutters via a wireless network (MQTT) or through a touch-sensitive wall switch. Cut the 4 buttons off the TTP224 and attach a wire to each cap. You will need 4 wires connected to the SonOff Dual (Vcc, GND, Button1, Button2). You must jumper on the TTP224: AHLB - Enable direct mode with CMOS active low output SM - Single key mode TOG - Optional if you want to use it as a switch instead of a push button Datasheet: http://www.tontek.com.tw/download.asp?sn=373 Software: https://github.com/hexxter/homie_rollo Bill of Materials: 1.
