No need of power supply. This very low power board gets the energy from the teleinformation output.
Sends its data with 433MHz transmitter using a protocole similar to the Lacrosse WS protocole.
The content of the transmitted data frame is discribed here.
Schematics, components, part list and printed board are available in pdf format
Source code written in PIC assembler and Hex code are available and generated with MPLAB IDE.
