Wattson is the free energy detective app that opens Cases, tracks your Energy Score, and shows you when grid power is cleanest and cheapest — near real-time smart meter data in your pocket.
Your smart meter already knows everything about your home's energy. Wattson makes that knowledge visible, clear, and useful.
Your smart meter records 5-minute interval readings around the clock — every kWh of consumption, solar generation, and battery activity. That data belongs to you.
Green Metering is your accredited Metering Coordinator — a licensed, regulated provider responsible for collecting and safeguarding your interval data. Think of us as the trusted link between your meter and your app.
You authorise Wattson at sign-up — explicit consent, tied to your NMI, revokable anytime. Your data stays yours. Wattson just helps you read it.
Near real-time charts, anomaly Cases, solar and battery visibility, demand response notifications — all in a free iOS and Android app.
You authorise access at sign-up and can revoke it any time. Your energy data is never sold or shared with third parties.
Every reading is Evidence. Every insight is a Deduction. Every alert is a Case. And every week, Wattson scores your performance — then tells your Echo Show or Nest Hub about it, hands-free.
5-minute interval readings direct from your smart meter, plus an instant live kW reading that refreshes every few seconds. Data the big retailers simply cannot match.
Live generation, self-consumption, grid export and battery state of charge — all from your meter, not an inverter estimate. Finally see what your system is actually doing.
Overnight spikes, phantom loads, appliance faults — when something unusual appears in your readings, Wattson opens a Case. You know before your bill does.
Live wholesale price indicator (LOW / HIGH) and renewable intensity (how green the grid is right now) — so you know exactly when to run the dishwasher, charge the car, or hold back.
A weekly 0–100 score combining your efficiency, solar self-sufficiency, demand response participation, and green grid alignment. Build your streak, earn rank promotions, track improvement over time.
When grid stress events are called, Wattson alerts you and shows your real-time reduction as it happens. See your impact live — not in a report seven days later.
Wattson lives on your kitchen bench or wall. The grid price indicator glows green when it's cheap and renewable, amber when it's moderate, red when demand is high. No app, no phone — just a glance while you make breakfast. Ask "Hey Alexa, ask Wattson what's on" and get a full voice summary instantly.
Wattson is free for end users — available through your electricity retailer, solar installer, or energy programme partner.
Offer Wattson free as a value-add. Weekly Energy Scores, streaks and rank progressions give your customers a daily reason to engage — and a reason to stay. The big retailers don't have this.
Live generation, self-consumption, export and battery state of charge — from your meter, not an estimate. Pair it with the green grid indicator to know exactly when to use your own power and when to sell it.
Live demand response feedback, grid renewable intensity, and a verifiable Energy Score backed by accredited meter data. The consumer-facing layer that VPP operators and demand response aggregators have been waiting for.
Register now for early access. When Wattson launches, you'll be the first to open your Case file, track your Energy Score, and finally see what your home has been hiding.
