Three housemates need a simple record when different people are home at month end. They create “River Street apartment,” add electricity in kWh, gas in m³, and cold water in m³, then place a focused QR label near each display. The workspace is private and contains no provider account numbers.
One routine replaces three chat threads
The shared note says to record all available meters on the final evening of the month. Whoever is home scans the relevant label, checks the meter name and location, and enters the exact cumulative value. Their display name makes follow-up possible without requiring an account.
Each device keeps its own unit and history
Electricity uses kWh while gas and water use m³. The water label says “hall cupboard” and the gas label says “kitchen balcony,” preventing a hurried contributor from entering a number against the wrong device. Copy buttons remain beside every QR for remote handoff.
A private receipt handles a mistyped digit
One housemate notices that 13,284.6 was entered as 13,824.6. They open the receipt saved after submission, correct the value, and confirm the surrounding readings still follow cumulative order. No compensating entry or manager intervention is needed.
The history supports conversation without pretending to bill
At the next month end the group can see the exact previous values and interval changes. A larger gas difference prompts them to confirm dates and weather, but they use the provider statement—not MeterBook—as the official source for charges and account reconciliation.
