Insteon is a home automation (domotics) technology that enables light switches, lights, thermostats, leak sensors, remote controls, motion sensors, and other electrically powered devices to interoperate through power lines, radio frequency (RF) communications, or both. It employs a dual-mesh networking topology in which all devices are peers and each device independently transmits, receives, and repeats messages. Like other home automation systems, it has been associated with the Internet of Things.

Insteon-based products were launched in 2005 by Smartlabs, the company which holds the trademark for Insteon. A Smartlabs subsidiary, also named Insteon, was created to market the technology.

Every message received by an Insteon compatible device undergoes error detection and correction and is then retransmitted to improve reliability. All devices retransmit the same message at the same time so that message transmissions are synchronous, thus preserving the integrity of the message while strengthening the signal on the powerline and erasing RF dead zones. Insteon powerline messaging uses phase-shift keying. Insteon RF messaging uses frequency-shift keying.

Each message contains a two-bit "hops" field that is initialized to 3 by the originating node and decremented each time a node in the network repeats the message. Individual Insteon messages can also carry up to 14 bytes of arbitrary user data for custom applications.

Insteon is an integrated dual-mesh (formerly referred to as "dual-band") network that combines wireless radio frequency (RF) and a building's existing electrical wiring. The electrical wiring becomes a backup transmission medium in the event of RF/wireless interference. Conversely, RF/wireless becomes a backup transmission medium in the event of powerline interference. As a peer-to-peer network, devices do not require network supervision, thus allowing optional operation without central controllers and routing tables.
