Here is a short list of some small projects I’m open sourcing.

Wireless TIC Bridge for French Electric Meters

French electric meters are equipped with a serial port outputting real-time power consumption data.

See this page for more information.

I’ve designed a small piece of hardware & software that allows for wireless transmission of this data.

The concept of this project is the following:

• The hardware can be directly plugged to the electric meter port. It will receive data and power from it.
• Real-time power consumption data is transmitted wirelessly and can be received with a matching USB receiver.
• Privacy is ensured through AES in CTR mode.

Hardware and firmware files are available here.
