Readings that exist, but that nothing ever lines up
You read the meter now and then, jot the index in a notebook or snap a photo of it. Then comes the question that matters: did the new water heater change anything? did last winter cost more than the one before? You would need to compare, and there is nothing to compare: scattered numbers and a supplier portal that shows only what the supplier chooses to show.
Energy tracking apps on the market assume a smart meter, a single supplier and a single energy source. A home heated with wood and hot water on electricity, a house with a water meter at the gate and a sub-meter in the workshop, an oil tank you dip by hand: none of that fits their boxes.
Your meters, described then generated
Describe your situation: “I want to track my home's consumption. I have an electricity meter, a gas meter and a water meter. I read the indexes myself: I record the date, the index and the consumption for the period. I also want to log my bills with their period and amount, keep my current contract, and see the evolution month by month.”
Blueprint Maker generates the matching application: the meters with their units, their dated readings, the bills and the current contract, plus a dashboard that finally puts the periods side by side.
- Meters: electricity, gas, water, heating oil, wood
- Dated readings: index, consumption for the period, note
- Bills: period covered, amount, billed consumption
- Current contract: supplier, plan, unit price, standing charge
- Consumption trend and running total since the start
The reading gets entered standing at the meter
The application is a web app at its own dedicated address. You read the index and enter it from your phone, on the spot, instead of holding it in your head until you get back to your desk — the exact moment the number becomes approximate.
It connects to no energy supplier: the values are the ones you enter, and they stay with you. That is a deliberate constraint, and it is also what makes it usable where no portal reaches — an old meter, a workshop sub-meter, a tank you dip, a cord of firewood you stack.
Free to start, and it's yours
The free Discovery plan generates a first complete application, often enough to track one home's meters. Paid plans let you iterate, with the cost shown before each generation.
The code is exportable: this consumption tracker is yours, with no ads and no data resale. Your readings don't become raw material for a third-party service, and they don't disappear if you stop a subscription.

Frequently asked questions: home energy tracking
Do I need technical skills to build this application?
No. You describe in plain language what you record: your meters, your periods, your bills; you validate a plan, and the application is generated without writing a line of code.
Does the application connect to my smart meter or my supplier?
No, not by default: you enter the indexes you read yourself. That is exactly what lets it track what no portal reports — a sub-meter, a heating oil tank, firewood. Since the code is exportable, a developer can add automatic retrieval if your supplier exposes an interface.
Can it track several energies and several meters?
Yes: describe the meters you actually read — electricity, gas, water, heating oil, wood — and the application tracks each one with its own history and its own unit.
Can I compare two periods, or two years?
Because readings are dated, the application shows consumption over a given period and how it evolves. A finer comparison — the same month year over year, an adjustment for how harsh the winter was — is asked for in the next generation, or added to the exported code.
Is it really free to start?
Yes: the Discovery plan generates a first application at no cost. The cost of further generations is shown before you launch them.
