linkynflux

Externals / Thanks

The excellent job done by outadoc on project linkindle available on Github. I used the linky module to avoid re-do the great job done.

Grafana example

Grafana Dashboard

Requirements

Python3 and libs

  • python3 and following dependencies
    • os
    • sys
    • datetime
    • locale
    • relativedelta (from dateutil.relativedelta)
    • tz (from dateutil)
    • InfluxDBClient (from influxdb)
    • linky (see Externals above)
    • json
    • argparse
    • logging
    • pprint (not mandatory, just for debugging)

If you want to debug, please set level=logging.INFO to level=logging.DEBUG

Enedis/Linky

Verify you have requirements by activating "Courbe de charge" on Enedis Portal

Please also remember kWh is provided by "ordre". So if you have a 30min step "ordre", you need to divide by twice kW per hour.

InfluxDB

Create database

Create d

> CREATE DATABASE linky
> CREATE USER "linky" WITH PASSWORD [REDACTED]
> GRANT ALL ON "linky" TO "linky"

Alter default retention and tune it as you want

Example : 5 years (1825d)

> ALTER RETENTION POLICY "autogen" ON "linky" DURATION 1825d SHARD DURATION 30m DEFAULT

DataPoints Format

{
  "measurement": "conso_elec",
    "tags": {
      "fetch_date" :        /DATE WHEN VALUE WHERE FETCH FROM API ENEDIS/,
      "heures_creuses" :    /1 IF ORDRE IS WHEN WE ARE IN "HEURES CREUSES", 0 IF NOT/,
      "heures_pleines" :    /1 IF ORDRE IS WHEN WE ARE IN "HEURES PLEINES", 0 IF NOT/,
      "heures_normales" :   /1 IF ORDRE IS WHEN WE ARE IN "HEURES NORMALES", 0 IF NOT/,
    },
    "time": '%Y-%m-%dT%H:%M:%SZ',
    "fields": {
      "value":    /VALUE IN Wh (SO x1000) AND DIVIDED BY 2 (ORDRE = 30min),
      "max":     /"PUISSANCE SOUSCRITE" RETURN BY ENEDIS in WH)/,
    }
}

Configure your own Parameters in .params

Well, yes it is dirty, but ... you can perhaps improve using vault or anything related to secret storage :D Please do an MR or fork if you have any better idea.

Copy .params.example to .params and fill with your own values :

  • enedis : username and password for API Enedis
  • influx : your InfluxDB database
  • hc :
    • if you have "heures creuses/heures pleines", fill start & end hours, so values will be tag with hc = 1 during this timewindow on InfluxDB datapoints
    • leave empty as [] if you don't have 'heures creuses' / 'heures pleines'
{
    "enedis":
    {
        "username": 	  "",
        "password": 	  ""
    },
    "influx":
    {
        "host": 	      "",
        "port": 	      8086,
        "db": 		      "",
        "username":     "",
        "password":     "",
        "ssl":		      true,
        "verify_ssl": 	true
    },
    "hc":
    [{
        "start":   { "h": 1, "m": 0 },
        "end":     { "h": 7, "m": 0 }
     },{
        "start":   { "h": 12, "m": 30 },
        "end":     { "h": 14, "m": 30 }
    }]
}

Grafana

Please verify first you have grafana-piechart-panel installed

# grafana-cli plugins install grafana-piechart-panel
# systemctl restart grafana-server

Replace DS_YOUR_LINKYDB with our own database source in Grafana dashboard grafana.dashboard.json and then import it

Change variables prices for (sorry only in french :D)

  • VAR_STD_KWH : "Tarif en € par kWh pour Heures pleines avec contrat option base"
  • VAR_HP_KWH : "Tarif en € par kWh pour Heures pleines avec contrat heures pleines/creuses"
  • VAR_HC_KWH : "Tarif en € par kWh pour Heures creuses avec contrat heures pleines/creuses"

Script usage

Test it !

If value is -1kWh it's because dataset return by Enedis API is empty (no idea how long data are available).

crontab

When it works, just put in a crontab to fetch last day (d=1) value (change $USER)

# cat /etc/crontab | grep linky
00 6    * * *   $USER    cd /hime/$USER//linkyndle &&  python3 linkynflux.py -d 1
