No MATTER what you are

Introduction

The most annoying problem in IoT product development is developing product for different echo systems. This is waste of a lot of money and time and also delay the time to market.

I am building an unified light bulb controller with matter. This project is so simple to thanks to the developers of matter protocol. And also resolve all the above mentioned problems in great scale.

The solution contains a matter enabled light bulb of course the heart and the brain of this IoT based bulb is nRF7002 DK from Nordic. I have already setup a thread boarder router (using Raspberry Pi and nRF52840 dongle from Nordic) and setup my laptop for commissioning. I am going to use M5Stack Core 2 with Alexa to control the light bulb.

Let's build together

This project is bit of length and I am trying my best to cover all the point as much as information. For this project we need following pieces.

• Matter accessory
• Matter gateway
• Matter controller

Matter accessory you can either use nRF Connect SDK sample Matter: Light bulb or Matter: Light switch. Let's see how to setup Matter: Light bulb sample.

You make sure to wire the component according to the diagram below. You need to have nRF Connect SDK and VS Code in order to program the DK. You can find more information on how to install VS Code here and nRF Connect SDK here.

Matter: Light bulb sample is also compatible with nRF52840 DK, nRF5340 DK and make sure to connect the relay module signal pin with DK LED 1 pin.

Connect your DK to the PC and create application using the sample in VS Code then run the below command in the terminal or click on build button in VS Code to build the application.

west build -b nrf52840dk_nrf52840 

If everything goes well proceed to Flash to upload the build (hex file) into the DK. Following the same process Matter: Light switch application can be built and flash ed into the another DK.

Here, you can find extensive information about how to setup the sample
