ISY-994i communication problems


Recommended Posts

Posted

I have an ISY-994i and approximately 35 Insteon devices on my system. The switches and programs worked properly until recently, when the program would start but the switches would not change state for that program.  These switches also cannot be controlled remotely by computer.  They function properly manually.  I have replaced the powerlinc modem, updated the ISY, restored all devices and links.  Any suggestions on where to check next.

The PLM might have lost its links or the connection between the ISY and the PLM is broken.

 

Remove the power from the PLM and the ISY, then power up the PLM, wait about 15 seconds then power up the ISY.

 

Let me know if that helped.
