Alexa on KNX
This project is proof of concept! With this project you can turn on and off up to 10 KNX devices with Alexa.
You need not additional libraries. All needed stuff is allready included and customized. KONNEKTING Suite beta4 is necessary for device setup
- KNX bus coupler (e.g. Siemens 5WG1117-2AB129)
- ESP8266 powered devices (e.g. WeMos R1 mini or NodeMCU)
|bus coupler||ADUM1201||WeMos R1 mini (ESP12)|
|VCC||1 + + 8||3.3V (VCC)|
|RX||2 < < 7||D8 (GPIO15)|
|TX||3 > > 6||D7 (GPIO13)|
|GND||4 - - 5||GND (GND)|
For debuging connect a USB-to-UART adapter: RX <> D4 (GPIO2) and GND <> GND.
