Electric sub-meter for furnished rentals: zero readings, fully automatic
The host no longer manages anything on the energy side. The sub-meter measures consumption in real time, the guest recharges on their own as needed, and comfort circuits cut off by themselves if the balance hits 0.
Reading the meter at every check-in? That's the first signal your model isn't scalable
In short-term furnished rentals, energy represents between 8% and 22% of annual expenses. Without a dedicated device, the host has only two options: either include a flat allowance in the nightly rate (at the risk of falling below actual cost), or ask the guest to pay their consumption at the end of the stay, which requires a manual reading of the main EDF meter at every arrival and every departure. Both scenarios are exhausting, and neither protects the margin.
An electric sub-meter — also known as a divisional meter or sub-meter — is a measurement device installed downstream of your EDF/Linky meter, inside your electrical panel. It measures the consumption of one or more circuits you connect: heating, air conditioning, water heater, guest outlets. Combined with a connected module and a recharge portal, it turns time-consuming manual management into an automatic system self-managed by the guest.
In practice: your main EDF bill stays in your name, with no contract change. The sub-meter transmits the guest's actual consumption in real time. The guest checks their balance via a QR code, recharges in 30 seconds through Stripe, and if credit hits 0, comfort circuits (heating, AC, water heater) shut off automatically. Lighting and standard outlets remain active — legal obligation. You, the host, no longer take any readings.
How a sub-meter works in a furnished rental
Three steps, one installation, then nothing else to manage
1. Installation by an electrician
Your electrician installs the Powtiva sub-meter (Pro EM-50 for studios to 4-bedroom units, Pro 3EM for three-phase villas) in your panel, downstream of the main breaker. Allow 2 to 3 hours of work. No changes to your EDF contract.
2. The guest recharges on their own
On arrival, the guest scans a QR code displayed in the property, accesses their personalized portal and recharges their energy credit in 30 seconds via Stripe. They choose the amount themselves based on the length of their stay and their habits.
3. Automatic shut-off and restoration
The sub-meter tracks consumption in real time. If the balance approaches 0, the guest receives an SMS or email alert. If credit runs out, comfort circuits (heating, AC, water heater) cut off by themselves — lighting and outlets remain active. A recharge = immediate restoration.
The sub-meter in furnished rentals: what the law says
Powtiva complies with the energy code, the consumer code and the loi ALUR. You are covered.
No electricity resale
You are not reselling electricity — you are re-invoicing at the actual cost measured by a certified sub-meter (class B, ±2% accuracy). The kWh rate you apply to the guest is equivalent to the one on your EDF bill. No CRE authorization required.
Lighting and outlets never cut
Article L115-3 of the code de l'action sociale guarantees minimum access to electricity. Powtiva ONLY cuts off comfort circuits (heating, AC, water heater). Lighting, standard outlets and the refrigerator always remain powered.
Compliant rental agreement
The energy billing method is mentioned in your Airbnb / Booking listing and in the stay conditions. The guest accepts it when booking. It is a stay condition, just like the nightly price or the tourist tax.
What the sub-meter changes for a host
Four concrete effects that show up with every host who installs Powtiva
Zero readings, zero admin
No more meter photos to request from the traveler, no more post-stay emails, no more spreadsheet calculations. The sub-meter reports consumption in real time, everything is logged.
Zero energy disputes
The guest sees what they consume, pays what they consume, in real time. End of post-check-out disputes, end of Airbnb credits tied to a contested energy bill.
Responsible guest behavior
When consumption is visible and paid, people switch off the AC when leaving and turn down the heating at night. Powtiva hosts measure on average -20 to -25% consumption compared to their flat-rate stays.
Host freed from the energy topic
You focus on hospitality and occupancy rate. The sub-meter, the guest portal, the alerts, the shut-offs and the recharges run on their own, 24/7, with no intervention.
Concretely: what the host no longer does
Typical day of an Airbnb host — before / after installing a Powtiva sub-meter
Without a sub-meter
- • Meter photos to request from the guest on arrival then on departure (or you go there yourself)
- • Manual consumption calculation, sending a billing email, follow-up if forgotten
- • Discussion / negotiation if the guest disputes — sometimes an Airbnb credit at your expense
You manage
at every check-in, every check-out, every EDF bill
With a Powtiva sub-meter
- • The guest scans the QR code on arrival and recharges their credit themselves as needed
- • Consumption reports in real time — no readings, no photos, no emails to send
- • If the balance hits 0, comfort circuits cut off on their own; recharge = immediate restoration
