Some IoT devices will get power from electrical systems, but many, such as door locks and standalone sensors, will use batteries. These devices send and receive small amounts of information intermittently or periodically. Consequently, the battery life of an IoT device can range from 1.5 years to a decade, if the battery lasts that long. One IoT maker, Insteon, uses both radio and powerline communication, which can send data over existing electrical wiring as well as via a radio, which it says will offer an increased measure of reliability.
