Welcome to the world of smart home automation! In this blog post, we’ll walk through the process of building a personalized Energy Assistant using Alexa Skill and the Octopus API to fetch gas or electricity usage data.
Overview
Our Energy Assistant can provide information on gas and electricity usage for the previous day, the current week, or the current month. It’s a handy tool for users who want to monitor and analyze their energy consumption.
Prerequisites
Before we dive into the code, make sure you have:
- An Alexa Developer account.
- An Octopus Energy API key.
- Node.js installed on your development machine.
Getting Started
1. Set Up Your Alexa Skill
Create a new Alexa Skill in the Alexa Developer Console. Configure the skill with the necessary intents, such as LaunchRequest, FuelUsage, and standard intents like AMAZON.HelpIntent.
2. Fetch Octopus API Data
We’ll use Node.js and the ask-sdk-core library to handle Alexa requests and communicate with the Octopus API. The makeRequest and fetchAllPages functions assist in fetching data from the Octopus API securely.

Conclusion
Congratulations! You’ve built your personalized Energy Assistant. Users can now ask Alexa about their energy usage, and the assistant will fetch and provide detailed information.
Feel free to customize and extend the functionality to suit your needs. Happy coding!
A wonderful serenity has taken possession of my entire soul, like these sweet mornings of spring which I enjoy with my whole heart.
I am so happy, my dear friend, so absorbed in the exquisite sense of mere tranquil existence, that I neglect my talents.
I am alone, and feel the charm of existence in this spot, which was created for the bliss of souls like mine. I am so happy, my dear friend, so absorbed in the exquisite sense of mere tranquil existence, that I neglect my talents.
I should be incapable of drawing a single stroke at the present moment; and yet I feel that I never was a greater artist than now.
When, while the lovely valley teems with vapour around me, and the meridian sun strikes the upper surface of the impenetrable foliage of my trees, and but a few stray gleams steal into the inner sanctuary, I throw myself down among the tall grass by the trickling stream; and, as I lie close to the earth, a thousand unknown plants are noticed by me: when I hear the buzz of the little world among the stalks, and grow familiar with the countless indescribable forms of the insects and flies, then I feel the presence of the Almighty, who formed us in his own image, and the breath of that universal love which bears and sustains us, as it floats around us in an eternity of bliss; and then, my friend, when darkness overspreads my eyes, and heaven and earth seem to dwell in my soul and absorb its power, like the form of a beloved mistress, then I often think with longing, Oh, would I could describe these conceptions, could impress upon paper all that is living so full and warm within me, that it might be the mirror of my soul, as my soul is the mirror of the infinite God!
O my friend — but it is too much for my strength — I sink under the weight of the splendour of these visions!
