@Fumée-Bleue
Maybe you could add an image and description to the project?

Nice project. I have done something with jeedom plugin through USB connection in a raspberry pi. However, how do you auto power supply your system?

On my linky i just use the 2 pins I1 and I2 to get the information and then i have 4m of cables until my raspberry pi to power on all the system. With NRF will be more usefull.

[Fumée Bleue]

jeremushka,
Thanks.
I updated the project description and added arduino sources. The pins I1 and A are used for power supply, and I2 for the datas.

hello,
well done for your project. I am interested but I have an error during the compilation. I'm bad at programming. can you help me.

C:\Users\Maison\Downloads\TeleinfoMySensors\TeleinfoMySensorsDecode.ino: In function 'void traitement_trame(char*, int)':

C:\Users\Maison\Downloads\TeleinfoMySensors\TeleinfoMySensorsDecode.ino:69:7: warning: unused variable 'i' [-Wunused-variable]

int i;

   ^

C:\Users\Maison\Downloads\TeleinfoMySensors\TeleinfoMySensorsDecode.ino:65:39: warning: unused parameter 'len' [-Wunused-parameter]

void traitement_trame(char *buff, int len)

                                   ^~~

Le croquis utilise 9328 octets (30%) de l'espace de stockage de programmes. Le maximum est de 30720 octets.
Les variables globales utilisent 921 octets (44%) de mémoire dynamique, ce qui laisse 1127 octets pour les variables locales. Le maximum est de 2048 octets.

thank you

@secator are you getting any errors? Doesn’t look like any problems in the part that you posted.

this messages are normal ?????

[mfalkvidd]

@secator maybe not normal, but definitely labelled as warnings and not errors.

[secator]

Do you use an Arduino Pro Mini 5v or 3.3V ?

[Fumée Bleue]

@Secator,
I use an Arduino pro mini 3.3 V in order to voltage compatible with the NRF24L01

[Fumée Bleue]

I created an 1.0.4 version without warning compilation. I removed "i" and "len" unnecessary variables.

thanks for you reply Fumée Bleue.
