What if a guest disputes the energy bill at checkout?

A settlement based on meter readings in arrears quickly feels like a surprise to guests, especially if it is unclear whether the measured consumption actually belongs entirely to their stay. You prevent this by making consumption visible during the stay itself: at Staywatt, the guest purchases credit in advance, sees their consumption live via a metering module that measures only that property, and receives no invoice afterwards. With a single property and occasional rentals, a clear meter reading photo shared in a timely manner is often sufficient. With shared installations such as a swimming pool, allocation always remains partly an assumption.
