Electric submeter for Airbnb: which model should you choose?
Mechanical, digital LCD, or connected prepaid? Discover how Airbnb hosts and furnished rental managers choose the right submeter for their energy refactoring strategy.
Why submeter choice is critical in Airbnb
In short-term furnished rentals, the vast majority of your guests change weekly. Unlike a traditional long-term tenant who occupies the property 12 months, an Airbnb host may have 40 to 52 different people per year. This rapid turnover makes traditional monthly mechanical meter reading impossible: you never see the same guest twice, and asking each one to read the meter is neither reliable nor professional.
Practical result: Airbnb property owners must choose between three submeter categories: mechanical (manual reading impossible in short-term), digital LCD (local reading only, no prepayment), or connected prepaid (only scalable solution to automate billing and hold guests accountable). On a small building of 5 studios with high turnover, this choice means the difference between absorbing €5,000 in annual energy charges versus refactoring them entirely.
Powtiva standardizes the connected + prepaid option, in compliance with NF C 15-100 standard and the November 15, 2019 decree on divisional meters.
Comparison of three submeter categories
Mechanical vs digital LCD vs connected prepaid: benefits and limitations
Mechanical (€30)
Mechanical meter: manual reading only, impractical in short-term rentals (reading impossible between stays).
LCD digital (€50)
LCD screen: local reading more legible but still no remote reading, same logistics problem as mechanical.
Connected prepaid (€76-€95)
Powtiva communicating meter: automatic remote reading, automatic refactoring, only viable choice for multiple properties.
Is a connected submeter legal?
Powtiva complies with all French regulations on electric submetering and tenant energy billing.
NF C 15-100 standard compliant
Our meters and relays are CE certified, tested for French residential use, and compliant with French electrical installation standards. Downstream installation from EDF meter = zero risk of regulatory violation.
November 15, 2019 decree on divisional meters
This text specifically governs electric submetering in rentals. Powtiva fully complies: accurate measurement, tariff transparency per kWh, 24/7 consultation rights, no cutoff of vital services.
Legal energy refactoring in short-term furnished rentals
Individual electricity refactoring is legal in short-term furnished rentals, provided it is based on accurate submetering and a kWh tariff is communicated to the guest before consumption. No EDF procedure or prefectural notification required.
