Fetch water usage data from Cyble meters

Primary LanguageC

No longer maintained

As I have new water meter (lora enabled), this project is no longer maintained by me. Feel free to fork it and develop further.

everblu-meters - Water usage data for Home Assistant

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

Hardware

Raspberry Pi Zero with CC1101 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. Install libmosquitto-dev: apt install libmosquitto-dev
  4. Set meter serial number and production date in everblu_meters.c, it can be found on the meter label itself: Cyble Meter Label
  5. Configure MQTT connection details in everblu_meters.c: MQTT_HOST, MQTT_USER, 'MQTT_PASS`
  6. Compile the code with make
  7. Run everblu_meters, after ~2s your meter data should be on the screen and data should be pushed to MQTT.
  8. Setup crontab to run it twice a day

Troubleshooting

Frequency adjustment

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.

Business hours

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).

Serial number starting with 0

Please ignore the leading 0, provide serial in configuration without it.

Save power

The meter has internal battery, which should last for 10 years when queried once a day.

Origin and license

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?
