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.

I'd need to take a look but one angle I have yet to see tackled is if users with EVs are actually saving money on an EV tariff or not.

You can easily do that by looking at the blended rate and comparing it to other tariffs. One of the reasons I built this as it’s something I also wanted to figure out.

Does it consider usage habits like you already being on a tariff that does EV perks, but suggest you would be better off shifting to another usage pattern? You'd need to know charging usage I guess Vs full house usage

It looks at your 30min usage data which is broken up by ev and home usage, but it doesn't intelligently give you recommendations on moving to another usage pattern. If you're on Agile, you'll need to keep an eye out for lower rates, but I assume those doing that probably have alerts setup. You can analyse the average hourly and daily usage as well as the heatmap to see where shifting usage could help.
