Is it supposed to work?

I purchased this to work with my x10 modules controlled by a vera AI. It does not control any of the x10 modules as the vera is sending commands but no responses.

Thankfully, they're back

All of my home automation runs on Insteon controllers. When the old organization disappeared, I looked to find a similar solution with no comparable units. A year later my 10-year-old PLM died. I searched the web for a replacement and found the new company. I bought the PLM and everything again works beautifully. I am a truly happy camper.

Thank you for your kind words. As Insteon users ourselves, we share your happiness :)

Flexible center of a home automation setup

Very happy with the INSTEON platform. This was a replacement for a PLM that ran flawlessly for over 5 years.

Fast and Accurate

Tired of the old serial version. It missed some devices during a scheduled event every few days. This USB version works very well. It hasn’t missed anything since it installed it.

Smooth Transition from ISY994 to Eisy

The USB Modem Interface (PLM) allowed me to transition my residential system with over 60 Insteon devices from the discontinued Universal Devices ISY994 hub to their newest product (Eisy). Everything is working flawlessly.
