Serial Modem Interface (PLM)

Part of a Larger, Smarter Family

The Serial Modem Interface allows third-party software control over a whole host of Insteon devices - from sensors to remotes, from switches to keypads, from plugs to switched outlets, Insteon has your Connected Home needs covered.

Level-Up Your Connected Home Control

When using the third-party controller software or app, you get the flexibility and control to easily add new devices, link devices together in scenes, and set schedules. For even more convenience, use a smart assistant like Amazon Alexa or Google Home to control your Insteon devices with your voice.*

It’s OK to Dip Your Toe In

Unlike other traditional “smart” devices that are focused on controlling one device or maybe one room, Insteon is a whole-home solution. You can start small with manually linking a few devices then “go big” by outfitting your entire home with the Insteon ecosystem with the Serial Modem Interface with third-party controller software. Our solutions can easily scale right alongside you as your Connected Home needs grow.

It Just Works

Other connected home switches use Wi-Fi or other radio-only signals. Insteon utilizes a patented dual-band mesh technology that communicates over both existing power lines and a wireless radio for unparalleled reliability and range.

Peace of Mind

Rest assured, you can receive instant notifications on your smart phone when a sensor has detected water, motion, or a door/gate has been opened.

* Exact functionality and features depend on what third-party software is used
