Octograph

This is now hideously out of date and unloved by me. Instead, check out https://github.com/Yanson/octograph where Iain has overhauled, extended and improved it in every way!

Python tool for downloading energy consumption data from the Octopus Energy API and loading it into InfluxDB.

If you think you'd find this useful, but haven't switched to Octopus yet, then you can follow my referrer link https://share.octopus.energy/vivid-emu-468 and you'll receive a £50 bill credit, and so will I :)

In the process, additional metrics will be generated and stored for unit rates and costs as configured by the user. Suitable for two-rate electricity tariffs like Octopus Energy Go. Single rate gas readings are also retrieved and stored.

The secondary unit rate is specified with start and end times, and a timezone which is useful for the Go tariff where the discount rate changes with daylight savings time.

Included is an example Grafana dashboard to visualise the captured data.

An example Docker Compose file is included for easily running InfluxDB and Grafana.

Installation

Tested on macOS with Docker for Mac and Python 3.6. A Python virtualenv is recommended.

Install the Python requirements with pip

pip install -r app/requirements.txt

Usage

Create a configuration file octograph.ini customised with your Octopus API key, meter details and energy rate information. This file should be in the working directory where you run the octopus_to_influxdb.py command, or can be passed as an argument.

python app/octopus_to_influxdb.py --help

By default, energy data for the previous day will be collected. Optional from and to ranges may be specified to retrieve larger datasets. It is anticipated that the script will be run daily by a cron job.

docker-compose up -d  # start InfluxDB and Grafana in Docker
python app/octopus_to_influxdb.py --from-date=2018-10-20
open http://localhost:3000

The default login credentials for Grafana are admin/admin, and you will be prompted to set a new password on first login. You should then proceed to add InfluxDB as a datasource with URL http://influxdb:8086 and database energy if using the Docker version provided. The dashboard provided can then be imported to review the data.
