How does my guest know how much electricity he has used?

Live consumption in the app, per kWh

The guest sees their electricity consumption directly in the app, based on the measurement that the module in the distribution board transmits. After scanning the QR code in the accommodation, the app opens without requiring an account; the guest purchases an amount of kWh there and from that moment sees the ongoing consumption and remaining balance. Once the balance reaches zero, the standard circuits switch off, while the circuit for the refrigerator continues to operate.

For a charging station this works in the same way: each station has its own QR code, its own rate and its own measurement, even when there is no accommodation involved but only a charging point is offered. What the guest sees is therefore always a current picture of what has been consumed and what credit remains, without having to log in anywhere or conclude a contract.

Basis: verified measurement and ACM framework

The fact that the guest can rely on the figures shown by the app is related to the requirements that apply to electricity meters: Directive 2014/32/EU sets out in Annex V requirements for the accuracy and reliability of measuring instruments for electricity, and those requirements form the basis for a measurement that can be considered reliable. In addition, the Authority for Consumers & Markets points to the rules that apply when delivering energy to third parties, such as guests in a rented accommodation; this framework is relevant to the way consumption is measured and charged to those who actually use the electricity.
