Hi,

Seem like your repo is about linking the KNX bus to the french linky electricity meter/breaker. Have you more information ?

What kind of hardware did you use? Some pictures and "howto" could be cool to add.

Dreaming about a knx-rf module directly powered be the linky ...

Thanks you for your effort.

Yes, this is for the french linky. The current hardware is a STM32L432KC connected to a TP-UART NCN51xx device. But the code should work for any thelsing/knx compatible device with some adjustments. It just requires you have the prog led, the prog switch, an uart connected to the TP-UART and the RX pin of a second uart connected to your linky. You may need to adjust some defines for this. There is just this one ADJ_UART_SPEED which should be set by default to 1200. There is a good description about the hardware required to retrieve the serial data from the linky here I will try to write a more complete description when I will have more time.
