What we measure, and what the law requires
A statement is only worth as much as the measurement behind it. Here is the step we record at, how we read any meter, how long we keep the data, and what you get at the end.
The quarter-hour, not the hour
Neolia can record data down to a fifteen-minute interval where the device allows it, which improves consumption tracking and the detection of drifts. It is especially useful in a self-consumption grouping, where allocation is calculated on fine-grained measurement.
An hourly interval is enough to draw a curve: on a real building, the same consumption allocated hourly rather than every quarter of an hour changes the result by several per cent. We do not, however, present the quarter of an hour as a regulatory requirement: it is a technical capability, and it depends on the meter installed.
Three years of curve, ten years of statement
The raw measurement is kept for 90 days, long enough to check everything and replay a disputed calculation. The quarter-hour aggregate is kept for three years, which lets you compare one winter with the last.
The accounting record is not the curve: it is the statement issued. That is what follows the usual retention period of an accounting document, ten years.
Three ways to read a meter, and we take all three
The protocol is our business, not yours. What matters to you is that a fitted meter is read, and still is in ten years.
The electricity meter already in place
The smart meters fitted by grid operators expose a local customer interface, often called the P1 port. We connect to it: nothing to replace, and measurements arrive continuously.
Worth knowing before you rely on it: in Switzerland this interface is disabled by default. It is enabled on an authenticated request to the grid operator, and the decryption key is sent separately. Allow several weeks between the request and the first measurement. We handle the request with you, but it cannot be caught up the day before handover.
M-Bus, the proven route
For heat, hot water and cold water, meters on a wired bus remain the safest route: a controller polls them and sends us the index readings. It is the route we can use most widely today.
It is also the universal safety net: if a meter cannot be read any other way, an auxiliary bus meter goes in downstream without touching the existing installation.
Without drilling a wall
In a renovation, pulling a bus through an existing riser is expensive and noisy. Radio meters avoid that work: they transmit to a gateway installed in the building, with no cabling between floors.
This is the route we are extending first, model by model. The exact model is confirmed with us before ordering: that check, and only that check, guarantees a fitted meter will be read on the day of commissioning.
What you get at the end
Individual, and verifiable
The individual statement for heating and hot water is drawn from measurements, not from an estimate. Every line traces back to dated readings you can bring out, which is exactly what a tenant who disputes asks to see.
Quarter-hour, when it matters
In a self-consumption grouping, the split between participants is calculated on fine-grained measurements, not on a monthly total. That is exactly why the step is fifteen minutes.
Your data stays yours
The readings export to a table, building by building and dwelling by dwelling, without going through us. If you ever change tools, you leave with your history.
