Vindriktning

Let's make the Ikea Vindriktning air quality sensor a little smarter. Here is the matching completely over-engineered firmware.

prerequisite

ESP32 - Mini D1
Ikea Vindriktning

Install

Clone this repository and open it with platformIO. Remember, the SPIFF must also be flashed. On a terminal in vscode you can do it with

pio run -t uploadfs
pio run -t upload

After that, take a look at your monitorport ...

When the output look like this, congratulation!

After the first start an access point will be opened with an unique name like

vindriktning_XXXXX

and an not so unique password

vindriktning

After that you can configure the vindriktning under the following IP-address with your favorite webbrowser

http://192.168.4.1

hardware modification in 4 steps

esp32 -> Vindriktning:

VCC -> +5V
GND -> GND
GPIO16 -> reset
