Can I see live what a guest is consuming?

You see the current consumption and the consumption of the current booking per accommodation, continuously updated and separate from what the guest sees themselves. The guest has their own screen with balance and consumption, which often means they top up or reduce usage themselves without you needing to intervene. You see totals per accommodation, not consumption per appliance, and the system does not provide automatic alerts for excessive usage. For occasional rentals or pure curiosity, a simple smart meter is probably sufficient.
