isy944i Power Supply

Recommended Posts

The power supply I received with my ISY944i has failed.  The ISY stopped working and I noticed that the network connectivity failed as well.  LED was dim so I tried a different power supply I had (5v, 1A, appears to be a 3.5mm plug) and it started up instantly.  Fixed.


What are the power supply requirements?   Can I use any 5V, 1A, 3.5mm jack power supply?


I am also using an Insteon 2413S PowerLinc Modem (PLM).  I saw on the Smarthome site that the PLM can power the ISY.  MY ISY was purchased in 2012, so not sure if this applies to mine.

Just had the same issue w/ my ISY994iZw that was less than 2 months old. I thought my ISY died at first, but since no lights were illuminating I gave a spare power supply a shot and it fired back up. I contacted support and Michel promptly sent a replacement.

You can also use higher voltage power supplies as ling as the polarity is correct. I've been using a 12VDC supply of which I have plenty.
