    Hey there, as you landed on this article you're probably annoyed that IKEA isn't so smart yet and you can't integrate it into your smart home and can't control it via Google Assistant or Alexa. No worries I'll tell you how you can control the IKEA lamps with a Raspberry PI, which you right now control with an Ansluta remote. The remote must be the model with a 2.4GHz chip and not with a 433MHz one. On the back of my Ansluta remote is the model number YH-KZQ-FS. If you have such a remote you can continue reading. Otherwise this article might be useless for you.

    What you need

    The Ansluta remote is using the CC2500 chip, which you can get for 3€ on Amazon. To ensure we definitely are able to replicate the commands we're going to use the same chip as well. Then we will use a Raspberry PI 3, which you can get for 33.99€ on Amazon to control the chip. For sure you also can use an Arduino, NodeMCU, ATTiny/ATMega or any other MCU. I used an Raspberry PI because I wanted to try out the

    Before some years I started beeing interested in smart home and especially in creating it by myself :) My first project was a tutorial to build a temperature sensor which sends the data to my raspberry gateway via 433MHz. As these tutorial were quite old I had to exchange some hard and software to make it work but it was a nice challenge. End of 2018 I then thought that it might be nice to enhance the sensor by measuring volatile organic compounds and CO2. Some could say that I could buy an existing sensor but you know, ... that wouldn't be fun :D

    Measuring volatile compounds

    After some research I decided to choose CCS811 chip for measuring the total volatile organic compounds (tVOC) because it was quite cheap and it can operate on 2.7V+, which was necessary because my existing setup is supplied by 3 AAA batteries. The chip can also calculate the estimated co2 value (eCO2) based on the tVOC. So I bought a CJMCU-8118 breakout on Amazon for around 15€ but you can buy it cheaper on
