Connect your Octopus Energy account to Wattlas

Energy tariff ~2 minutes
Diagram: your smart meter already reports to Octopus Energy; Wattlas reads the same account with a read-only API key

What you'll need

Connecting this account requires Wattlas Plus.

  • An Octopus Energy account with a smart meter reporting
  • An API key from your online dashboard, and your account number (e.g. A-1234ABCD)
  • About 2 minutes - Octopus only shows the key once, so keep the tab open

Connect it in Wattlas

  1. Get an API key from Octopus

    Sign in and go straight to Octopus's API access page - that link takes you directly there (Personal details → Developer settings → API access), no menu-hunting needed. Copy the key immediately: Octopus only shows it once, so save it somewhere safe if you'll want it for other services too.

  2. Open Setup → Tariff in Wattlas

    Tap the gear icon top-left of the app, then the receipt icon for the Tariff tab, and switch tariff mode to Octopus.

  3. Enter your API key and account number

    This is the exact form you'll see:

    Connect your Octopus account

    Auto-detects your current tariff, and unlocks your real household usage in place of an estimate - on top of whatever inverter you've connected above.
    API key
    sk_live_...
    Account number
    e.g. A-1234ABCD
    Connect account

  4. That's it - everything else auto-fills

    Wattlas detects your current tariff and standing charge, and - if your account has Intelligent Octopus Go with a car linked - picks up its smart-charge dispatch windows automatically. See our IOG dispatch tracking post for what that looks like on the chart.

Wattlas only ever reads. It has no write access to your Octopus account - it can't switch your tariff, make payments, or change any setting. Disconnecting deletes the stored API key and everything cached alongside it (meter, detected tariff, smart-charge device) from our database.

Common questions

Do I need to be on Intelligent Octopus Go for this to work?

No - any Octopus tariff works for real household usage and auto-detected rates. Intelligent Octopus Go specifically also unlocks smart-charge dispatch-window tracking, if your account has a car linked.

Can Wattlas move money, switch my tariff, or change any setting on my Octopus account?

No. Wattlas only ever reads from your Octopus account through their own API - it can't switch tariffs, make payments, or change anything. Disconnecting deletes the stored API key and everything cached alongside it.
