Good evening
This is most lightly possible but I want to make sure before I start to hack and modify my Home Assistant
At the moment I am on the Flux Tariff with 3 helper sensors to help me to monitor my power usage, “cheap, normal, high” and I have place within my energy dashboard
but in a few months I am going to move over to Agile, where the cost of the KHW change every 30 mins
the ideal is to run the house off the cheap rate from agile by charging my battery when it is cheap and then allowing the house to run off the battery.
I am not to concern about having any automation or scripts running off the value of the Khw, as I created a import script that will charge my batteries which I will set manual every day.
I have discovered and read about the Integration for the agile into Home assistant, but I can’t see the answers to the following questions.
is there a sensor that only shows the current rate and then updates every 30 mins.
is there a sensor that calculations the total Khw / cost for every hour that will work with the energy dashboard or do I have to do something fancy like having two sensors link to the helper ( one for the Khw and a second helper for the changing cost ? “

Using the HACs Home Assistant Octopus Energy you can set a sensor that will be on for x number of cheapest periods. Works great 
is this a array or or a single sensor that shows the current value ?.
last night I have chosen to stand up a new Home Assistant just for testing, as I also have GivTCP for my Solar / battery readings.
It’s a single sensor. On/off
The BottleCapDave integration is fully featured and a very mature integration. It supports everything that you need to use the energy features - no hacking around.

Order an Octopus Mini, which will further improve things for you on Agile.
As Scriven33 says the BottleCapDave HACs add on is the one.
Target Rate Sensor(s) - Home Assistant Octopus Energy (bottlecapdave.github.io)
Work great.
Scriven33, what advantage does the Mini have?
Live readings. Otherwise you are limited to what the integration gets from the API, which updates every 30 minutes and sometimes longer.
thanks for the information, I will look into the mini octopus - but I current have Hildebrand device which I purchase about a year about that allows me to monitor my electric usage.
I’m currently trying to set a sensor up so that I can highlight the cheapest half hour slots over 3 hours in total (6 slots) from the next day Agile prices. It’s the Custom Octopus Energy Rates Card that takes it’s data from the BottleCapDave Octopus Energy integration.
When I try create a Rolling Target Rate sensor, I get a “Invalid Target Name” error.
Can anyone point me in the right direction to what I should put in the “Name” field?
