1. Compare Smart Energy Tariffs Using Your Actual 30-Minute Consumption Data

Generic energy comparison websites estimate your bills using crude annual averages—which is useless for modern smart tariffs like Octopus Agile, Octopus Go, Intelligent Octopus Go, or Octopus Tracker. Whether you save or lose money on a time-of-use tariff depends entirely on *when* during the 48 daily half-hourly slots your home or office consumes electricity: running an EV charger, heat pump, or immersion heater between 00:30 and 05:30 vs. cooking and heating during the expensive 16:00–19:00 wholesale peak.

Our Octopus Energy Smart Meter Advisor (/settings/advisers) connects directly to the official Octopus Energy REST API using your personal API key, MPAN (electricity), and MPRN (gas). Charles AI and the Energy Tariff Advisor ingest your real half-hourly kWh smart meter intervals, map your baseload vs. peak-window consumption, model how shifting EV charging or battery storage changes your effective unit rate (p/kWh), and show which tariff minimizes your annual bill.

Direct Octopus Energy Half-Hourly API Sync

Pulls your exact 30-minute electricity (MPAN) and gas (MPRN) smart meter consumption intervals directly from Octopus Energy’s API.

Agile, Go, Tracker & Flexible Tariff Modeling

Calculates what your actual consumption would cost across standard Flexible, overnight EV (Octopus Go / Intelligent), wholesale Tracker, and half-hourly Agile tariffs.

16:00–19:00 Peak Exposure & Baseload Audit

Quantifies what percentage of your daily electricity happens during the expensive 4pm–7pm peak window and measures your overnight standby baseload.

EV, Home Battery & Heat Pump Load-Shift Simulator

Simulates the exact pound-and-pence savings of shifting high-draw appliances, EV charging, or home battery charging into off-peak or plunge-pricing windows.

2. How to Connect Your Octopus Energy Smart Meter in 3 Steps

Every Octopus Energy customer gets free, instant access to their own smart meter API key inside the Octopus web dashboard.

Step 1: Copy Your Octopus API Key, MPAN & Serial Numbers

Step 1 • Octopus Developer Dashboard

Log in at octopus.energy → Personal Details → Developer Settings, and copy your API key along with your electricity MPAN/serial and gas MPRN/serial.

Read-only telemetry access; never initiates a tariff switch without you.

Step 2: Save Your Smart Meter Credentials

Step 2 • Connect in /settings/advisers

Open /settings/advisers, select the Octopus Energy Advisor card, and paste your API key and meter identifiers.

Immediately fetches your recent half-hourly kWh consumption intervals.

Step 3: Review Your Optimal Tariff & Off-Peak Savings Plan

Step 3 • Tariff & Load-Shift Analysis

Inspect your daily usage curve, compare effective p/kWh unit rates across tariffs, and see how much you can save by shifting heavy loads outside 4pm–7pm.

Pairs with /receptionist/costs to track monthly utility bills.

3. Autonomous Workflows Powered by the Octopus Energy Advisor

Half-Hourly Profiling

Real-Usage Smart Tariff Backtesting

Replays your actual historical 30-minute kWh usage against regional Octopus tariff rates to prove which tariff wins for your exact lifestyle or office schedule.

Peak Avoidance

4pm–7pm Peak Cost Reduction Plan

Identifies days with heavy 16:00–19:00 consumption spikes and calculates the annual savings of moving dishwasher, laundry, or heating cycles by two hours.

EV & Battery Optimization

Overnight Cheap-Window Arbitrage Modeling

Models charging your EV or home battery at 7p–8.5p/kWh overnight instead of paying 24p+/kWh daytime standard rates.

Financial Ledger Sync

Utility Cost Tracking with Charles AI

Combines your smart meter consumption insights in /settings/advisers with your energy bill invoices captured in /receptionist/costs.

4. Frequently Asked Questions

Will connecting my Octopus API key automatically switch my energy tariff?

No. Your Octopus Energy API key provides read-only access to your smart meter consumption and tariff rates so our advisor can calculate your optimal options safely.

Where do I find my MPAN, MPRN, and meter serial numbers?

They are listed right on the same Octopus Energy "Developer Settings" page where you copy your API key (as well as on any PDF energy bill).

Why is 4pm to 7pm so important on Octopus Agile?

Between 16:00 and 19:00, UK national grid demand peaks and wholesale distribution charges surge. Avoiding heavy appliance or EV usage during those three hours is the single biggest lever for unlocking massive savings on Agile.

Does this work for both home offices and commercial premises on Octopus?

Yes. Any SMETS1 or SMETS2 smart meter connected to an Octopus Energy account with half-hourly data available in the Octopus API is supported.
