As I have new water meter (lora enabled), this project is no longer maintained by me. Feel free to fork it and develop further.
Fetch water/gas usage data from Cyble EverBlu meters using RADIAN protocol on 433Mhz. Integrated with Home Assistant via MQTT.
Note: HASS autodiscovery is still missing, during development.
Meters supported:
- Itron EverBlu Cyble Enhanced
The project runs on Raspberry Pi with an RF transreciver (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)
- Enable SPI in raspi-config.
- Install WiringPi from https://github.com/WiringPi/WiringPi/
- Install libmosquitto-dev:
apt install libmosquitto-dev - Set meter serial number and production date in
everblu_meters.c, it can be found on the meter label itself:
- Configure MQTT connection details in
everblu_meters.c:MQTT_HOST,MQTT_USER, 'MQTT_PASS` - Compile the code with
make - Run
everblu_meters, after ~2s your meter data should be on the screen and data should be pushed to MQTT. - Setup crontab to run it twice a day
Your transreciver module may be not calibrated correctly, please modify frequency a bit lower or higher and try again. You may use RTL-SDR to measure the offset needed.
Your meter may be configured in such a way that is listens for request only during hours when data collectors work - to conserve energy. If you are unable to communicate with the meter, please try again during business hours (8-16).
Please ignore the leading 0, provide serial in configuration without it.
The meter has internal battery, which should last for 10 years when queried once a day.
This code is based on code 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?
There is a very nice port to ESP8266/ESP32: https://github.com/psykokwak-com/everblu-meters-esp8266
