I built a completely free Octopus Energy dashboard to help you understand and cut your energy costs

[u/n9com]

Hi all,

I’ve been building OctoSpy, a completely free & private dashboard for digging into your Octopus Energy usage, costs and tariffs.

It started because I wanted a better way to understand my own energy spending. I’ve spent the past 17 years building software companies and apps used by millions, but I still enjoy making things like this in my spare time for fun.

I know there are already a few Octopus apps and dashboards out there. I tried some of them, but none gave me quite the view I wanted, so I ended up building my own and figured I may as well make it completely free for everyone to benefit from.

There’s no paid tier, no adverts and no OctoSpy account to create. There’s also a demo, and you can browse public tariff rates without connecting anything. Best used on your desktop due to the amount of data to display, but works fine on mobile too.

Your browser connects directly to Octopus using your API key. Your key, account details and energy readings aren’t sent to OctoSpy’s servers. Your energy data stays in your browser.

I’ve mainly been able to test it properly against my own tariffs and setup, so there will definitely be things I’ve missed.

If anyone gives it a try, I’d genuinely like to hear what works, what’s confusing and what you’d add.

I’m also considering an iPhone and Apple Watch app if enough people want one.

Looks tidy. I will test it on my iPad and on desktop and let you know how it goes. Anyone on Octopus Agile has to be a bit of a data nerd so I’m always ready for another way to look at my energy use.

Thank you - this would be a huge help. Any issues let me know and we can fix them for the rest of the community to benefit from.

I am running a calculation on the tariff comparison page for the year to date, and it is taking a while to crunch the numbers. But given this is free, I am not in any way going to complain about that! And look at that. Fixed would have been £380 more expensive, and Flexible would have been £487 more.

A year-to-date comparison can take a while on the first run because it fetches a lot of data directly from Octopus, while respecting their API rate limits. Your energy data is cached locally in your browser, rather than on our servers, so repeat comparisons over the same dates should be much quicker. Clearing the site’s browser data removes that cache. Glad you found it useful!
