MatterEverything - Smart Electric Socket powered by Matter

Problem

Matter is now playing a significant role in the area of smart connected device. Nowadays you can integrate your smart devices from different suppliers into the same network and can make these devices communicate with each other. Unfortunately not all the devices we have at home are Matter Compatible or even smart, so replacing these devices with new matter devices would increase our electronics wastes which are hard to get rid of. So if we have a way to convert out old, not smart devices to a Matter enabled devices this would be a great deal.

Solution

In thin project we are presenting the device can be used with your old devices, for example : Water Boiler, lamps.. etc and convert it into a matter enabled device that allow you to integrate this device into your smart home network. Consider it as a magic electric socket that would Matter Everything, not only that but the device is also used to measure the current consumed by the connected device.

Electronics

Arduino Nano Matter is the brain of the device which is responsible for providing the connectivity for the device and Calculating the current consumed by reading the ADDC values from the current sensor. The Arduino Nano is also used to control the LCD in the device to shows the current consumption, and finally controlling the Relay that would allow AC current to the connected device. A custom PCB was made based on this design.

Electrical Wiring : (Caution 220v AC)

The Arduino Nano Matter was providing the the 220v AC by controlling a relay that is connected to the 220v supply, the Current sensor was also connected to the AC line to measure the current consumption.

Enclosure

To make the project usable, a 3D-printed Enclosure was design to have all the components, and prevent touching 220v AC line.

Software

The Software was developed using Arduino IDE. The SW main feature was Matter Connectivity as an endpoint device that would Enable/Disable the AC power. Not only that the SW reads the Current sensor date to calculate the actual current values based on these data, then shows the current on the display.
