Tasmotize IKEA VINDRIKTNING + custom 3D case* + multiple sensor*

Hardware required:

• NodeMCU
• IKEA VINDRIKTNING
• BMP180 sensor (optional)
• DS18B20 sensor (optional)
• Display SSD1306 (optional)
• Some wires
• 3D printer (optional)

Software required:

• Visual Studio Code (for building firmware) (https://code.visualstudio.com/)
• Tasmotizer (for flash firmware) (https://github.com/tasmota/tasmotizer)

Step 1. - Prepare firmware

To Tasmotize a VINDRIKTNING sensor, a custom firmware is required. This firmware must contain the necessary functions for this and the sensors we will connect.

Build Tasmota firmware:

• This tutorial can be used to create a custom firmware in Visual Code. https://tasmota.github.io/docs/Visual-Studio-Code/#hint
• In the file - user_config_override.h we must add the following code sequence:

• We build the customized firmware and upload it to the NodeMCU.

Step 2. - Prepare hardware

Solder a wire from GPIO14(NodeMCU) to REST pin from Inside of VINDRIKTNING.

Step 3. - Config the Tasmota

Step 4. - Optional 3D Case

Download this STL. Print and add all sensor and NodeMCU inside.

Step 5. - Optional Sensor BMP180, DS18B20 + Display SSD1306

Wire BMP180 and SSD1306 at GPIO4 and GPIO5

Wire DS18B20 at GPIO12

Step 6. - Optional rules to show on screen

Write in console this rule:

rule1          

      on tele-BMP180 do DisplayText [z] [fp] [s2c2x40y0][t] endon         

      on tele-BMP180#Temperature do DisplayText [s2c1x10y23] %value%C endon        

      on tele-VINDRIKTNING#PM2.5 do DisplayText [s2c1x80y23] %value%u endon        

      on tele-DS18B20#Temperature do DisplayText [s1c1x50y50] %value%C endon        

Activate rule with this command:

rule1 on
