Abstract: In an embodiment, a method facilitates battery replacement in a smart-home system. The method includes measuring, by one or more smart-home devices, at least one characteristic of a first battery in one of the smart-home devices, and determining from the at least one characteristic, whether replacement of the first battery is warranted. If replacement is warranted, the method sends an electronic order to a supplier for a replacement battery. The method further includes reading, by one or more of the smart-home devices, a machine readable code that accompanies a shipment of the replacement battery, embodying information from which an identity of the first smart-home device can be determined; determining, based at least in part on the information, a location of the first smart-home device; and providing, by one or more of the smart-home devices, visual and/or audible information to guide a user to the first smart-home device.
