CANx – Open standard for smart buildings, IoT and M2M

CANx is an open and free protocol designed for building automation, IoT, M2M and remote measurement or control. It allows simple and affordable devices to communicate with powerful computers or operate autonomously, over any communication medium. No licenses, fees or patents are required.

Reliable technology: Built on a proven CAN FT bus, widely used in the automotive, aerospace and railway industries.

European quality: Fully designed, manufactured and assembled in Europe with high quality components.
