everblu-meters

Fetch water usage data from Cyble EverBlu meters using RADIAN protocol.

Hardware

Currently the project runs on Raspberry Pi with an RF transreciver (CC1101).

Connections (rpi to CC1101):

• pin 1 (3V3) to pin 2 (VCC)
• pin 6 (GND) to pin 1 (GND)
• pin 11 (GPIO0 ) to pin 3 (GDO0)
• pin 24 (CE0) to pin 4 (CSN)
• pin 23 (SCLK) to pin 5 (SCK)
• pin 19 (MOSI) to pin 6 (MOSI)
• pin 21 (MISO) to pin 7 (MISO)
• pin 13 (GPIO27) to pin 8 (GD02)

Configuration

1. Enable SPI in raspi-config.
2. Install WiringPi from https://github.com/WiringPi/WiringPi/
3. Set meter serial number and production date in cc1101.c, it can be found on the meter label itself:

Compiling

gcc radian_trx.c -o radian_trx -lwiringPi -lpthread -Wall

Troubleshooting

Frequency adjustment

Origin and license

This code is fetched from http://www.lamaisonsimon.fr/wiki/doku.php?id=maison2:compteur_d_eau:compteur_d_eau

The license is unknown, citing one of the authors (fred):

I didn't put a license on this code maybe I should, I didn't know much about it in terms of licensing. this code was made by "looking" at the radian protocol which is said to be open source earlier in the page, I don't know if that helps?
