Where do I hang the QR plate for the metering module?

Don't hang the sticker by the front door, where it gets lost among house rules and key safes, but in a place the guest will look at anyway: next to the light switch, on the kitchen counter, or in the information folder. In large properties or those visited late in the evening, you can duplicate the same code in a second location, such as by the bed. If the property has a charging station, give it its own code by the station itself. If guests can't scan due to poor signal, the problem is with the connection, not the sticker placement.
