Octopus Agile custom component for Home Assistant

No longer maintained

This project is no longer maintained, feel free to open pull requests and I will merge them, although I am unable to test. If you would like to adopt the project please get in touch!

Installation

Clone this repo and copy custom_components/OctopusAgile to /custom_components/OctopusAgile

Alternatively, install via HACS

Configuration

NOTE: the GUI configuration flow is currently not implemented.

See the example configuration.yaml config below

region_code

This should match the DNO region code as per the Octopus Agile API - look for "E-1R-AGILE-18-02-21-" on your API dashboard and the next letter is your region code.

mpan, serial, and auth

Your MPAN and serial number are listed on your API dashboard page. "auth" is your API key from the same page.

agilerate

As of July 2022 there are now 3 Agile Tariffs :

• AGILE-18-02-21 - The unit rate is capped at 35p/kWh (including VAT)
• AGILE-22-07-22 - The unit rate is capped at 55p/kWh (including VAT)
• AGILE-22-08-31 - The unit rate is capped at 78p/kWh (including VAT)

default if not set is AGILE-18-02-21

moneymakers

The concept of moneymakers is devices that should always turn on if the price drops to 0 or below. This can either be a switch or climate device. Note that I have only tested this with my tado thermostat. Populate params as per the example for climate.

Moneymakers are added to the octopusagile.timers entity which is then checked at the beginning of each half hour to decide if the device should be on or off.

timers

Timers are used to turn devices on for a set number of hours each day. I have been using this to turn my immersion heater on for 5 hours a day at the cheapest half hour periods. day_from/day_to can be either "today" or "tomorrow", this is in reference to when the timers are updated (currently hardcoded to 1900Z each day)

Moneymakers are added to the octopusagile.timers entity which is then checked at the beginning of each half hour to decide if the device should be on or off.

The concept of requirements is best explained with an example. My water heater should turn on for 5 hours each day, however it should run for at least and hour between 1900 and 0600 and at least an hour between 1000 and 1600 to ensure that we always have hot water.

Hopefully the other options are self explanatory.

run_devices

This creates a entity detailing the best time period to run a device that needs x number of hours to run. Taking the dishwasher as an example, it runs for 3.5 hours but most energy is used in the first 2.5 so base the run time on 2.5 hours. I want to run the dishwasher before 0800 each night. An entity named octopusagile.dishwasher is created in Home assistant.

sensor

Create a sensor for each of: current rate, previous rate and next rate

Entities

octopusagile.rates

All future rates stored in entity attributes

octopusagile.avg_rate_exc_peak

The average rate from the day update_timers runs at 23:00 to 22:30 the next day, excluding the 16:00 to 18:30 time periods where the peak rate is applied.

octopusagile.avg_rate_inc_peak

The average rate from the day update_timers runs at 23:00 to 22:30 the next day, including the peak.

octopusagile.timers

All timers as created by the timer configuration listed in entity attribute

octopusagile.region_code

Region code as set in configuration

octopusagile.half_hour_timer_nextupdate

When the half hour timer will next run

octopusagile.half_hour_timer_lastupdate

octopusagile.<run_device_name>

A seperate entity for each configured run_device with the time stored in state and start time, start in, end in and average rate stored in the attributes

Example usage

Dashboard

Note that i am using an owl energy monitor for the energy usage stats. I will look at pulling these stats direct from octopus once my agile account is setup

Development

This repo uses pipenv to manage Python versions and dependencies. To get up and running:

• Install pipenv if you don't already have it.
• Run pipenv install to install any required packages and create the right python environment.
