Fetch water/gas usage data from Cyble EverBlu meters using RADIAN protocol on 433Mhz. Integrated with MQTT.
Meters supported:
- Itron EverBlu Cyble Enhanced
Software original code (but also all the hard work to get thingd working was originaly done here then put on github by @neutrinus here and then forked by psykokwak
I added some changes to the original firmware to work with my custom esp32-c3 board (including RGB led control, battery monitoring, deepsleep, battery charger), just plug, and play.
The project runs on ESP32 with an RF transreciver (CC1101).
Hardware can be any ESP32+CC1101 with correct wiring.
I used my open source one cc1101-e07-pi, you can check it out for the already made hardware or look at the original repo if you want to build your own.
All configuration is done thru platformio.ini file
You need to get your meter serial and year, it can be found on the meter label itself
Then put values in platformio.ini removing leading 0 from serial (mine was 0828979 I put 828979
-D METER_YEAR=22
-D METER_SERIAL=828979Set the hour/min and retries mode of wakeup to read data
-D WAKE_HOUR=08
-D WAKE_MIN=15
-D RETRIES=6
-D RETRIES_DELAY=15 Here, each day at 08H15, if read fails it will retry 15min later and do that until it worked or 6 times maximum.
So in case of all reads fail, last retry will be at 09H45 and then stop retries.
Process will start back at 08H15 next day.
Set your WiFi credentials and time zone see timezone.h
-D WIFI_SSID=\"YOUR-SSID\"
-D WIFI_PASS=\"YOUR-PASSWORD\"
-D TIME_ZONE=TZ_Europe_Paris ; See timezone.h of ./src folderAnd then MQTT related
-D MQTT_SERVER=\"192.168.1.8\"
-D TOPIC_BASE=\"everblu/\"
-D MQTT_USER=\"\"
-D MQTT_PASS=\"\"
-D MQTT_PORT=1883
;-D PUBLISH_RAW ; Enable to publish also RAW values (keeping JSON)If you need MQTT auth please do like that
-D MQTT_SERVER=\"192.168.1.8\"
-D TOPIC_BASE=\"everblu/\"
-D MQTT_USER=\"MQTT_USER\"
-D MQTT_PASS=\"MQTT_PASS\"
-D MQTT_PORT=1883
;-D PUBLISH_RAW ; Enable to publish also RAW values (keeping JSON)Base topic is everblu followed by serial number (with leading 0 this time) followed by -espabcd, because I've also device with PI so I need to know who is sending data, of course you can remove it if needed.
everblu/cyble-22-0828979-espbf84
When read suceeded, results are sent in JSONformat to the base topic plus json

}Values can also be sent in raw format enabling setting PUBLISH_RAW in platformio.ini

When read failed, results are sent in JSON
Example received on everblu/cyble-22-0828979-espbf84/error

"esp_battery": {

"type": "No Data",

}When read fail, device will follow RETRIES and RETRIES_DELAY parameters of platformio.ini (see above)
When scanning, results are sent in real time to the base topic plus scanning
Example received on everblu/cyble-22-0828979-espbf84/scanning
the format is JSON
{
"ts": 1689416825,
"date": "Sat Jul 15 12:27:05 2023",
"frequency": "433.8226",
"register", "0x10AE7C",
"rssi": -87,
"lqi": -120,
"result": 115
}result is below 0 on fail, -2 if data can't be read, -1 if read but saw an error else it's #reads of the counter (so positive)
When scanning done results are sent to the base topic plus scan
Example received on everblu/cyble-22-0828979-espbf84/scan
If frequency is 0 this mean no working frequency has been found.
{
"ts": 1689419164,
"date": "Sat Jul 15 13:06:04 2023",
"frequency": "0.0000",
}If frequency is found it will be the center frequency of the working frequencies boundaries. Boundaries will be sent also.
{
"ts": 1689419164,
"date": "Sat Jul 15 13:06:04 2023",
"frequency": "433.8000",
"min": "433.7900",
"max": "433.8100"
}Before going into deep sleep until next try or programmed hour WAKE_HOUR of platformio.ini the device will send a JSON message to topic sleep_until
Example received on everblu/cyble-22-0828979-espbf84/sleep_until
{
"seconds": 29526,
"ts": 1689656406,
"date": "Tue Jul 18 07:00:06 2023"
}Your transreciver module may be not calibrated correctly, please find working frequency enabling a scan by setting FORCE_SCAN in platformio.ini
-D FORCE_SCAN ; // Force a frequency scan on bootOnce found device will save frequency and use it on each boot.
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.
{
"hours":"06:18"
}Mine is working from (06-18) and this results looks like LocalTime (tested in summer) because working form 06:00 to 18:59 but yours may be different. I would suggest on first try to test between 10:00 and 16:00.
Anyway mine can't be read on Saturday/Sunday but works on off day such as July 14th.
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.
As basic advice, Please do not query your meter more than once a day
According Water manager here they need to change about 10/15 on each measure session, my previous one from 2017 was not working anymore, now they came and put a new one.

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
