Having a KNX IP backbone with IP routers working I wanted to see if I can build some DIY sensors using it, and check if this is a stable solution for non-critical use cases.
After building a module using ESPHome, I thought of converting it using KNX IP (ie. broadcast over WiFi to a broadcast address to report sensor values)
Install Arduino IDE if not done yet.
Go to https://www.arduino.cc/en/software and download version for your OS.
On Linux do not install via sudo apt install Arduino, it's old!
Unpack the archive and run sudo ./install.sh from it.
Next, open Arduino IDE and go to [File => Preferences]. A dialog box appears. In this box, an additional board manager URL text box is present.
- Copy and paste the following URL into the box and click OK to download the packages.
- Go to board manager and look for esp8266, install it.
- Then select board Wemo D1 from the board's menu.
Now we need to install the esp-knx-ip library.
Go to the GitHub page and under releases download the zip, I have version https://github.com/envy/esp-knx-ip/archive/0.4.0.zip
- Open Sketch menu Library menu, select Include Library and Add .ZIP Library
- Select downloaded archive
Do the same with the ESP8266 library from here, https://github.com/esp8266/Arduino/releases/download/2.7.4/esp8266-2.7.4.zip
- Open Boards manager and install esp8266
