I know this forum is usually about the isy994 unit only, but I have a very weird issue that just occurred with my setup. I have been running the current configuration problem free for about 6 years now.
I am running an isy994 in conjunction with the usual Insteon AC interface plus the recommended 32 bit transceiver from WGL (V572RF32) connected to a XTB 523 X10 power line interface.
My problem happened yesterday.
After a power outage of just over an hour, I noticed the RF unit did not respond to a small remote I was using. I figured it was the batteries, and went to work planning to swap out the batteries when I came home.
The batteries were not the issue. I tried several different remotes with the same issue occurring. I figured the RF unit had developed a problem after 6 years of great service, so I removed it to temporary replace it with a standard TM751 Transceiver.
That's when I went down the rabbit hole so to speak. No matter what transceiver or remote I used, none had any effect. Further investigation revealed that all remotes used with any transceiver now had a very limited range of abut 6 to 8 feet from the transceiver placed anywhere in the house.
The isy994 still transmits it's commands fine, and a control console connected to AC will still interact. The problem is just with the RF signal being squashed for some reason.
I have several house codes in use making it a bit more difficult to use the old X10 transceivers.
Any useful insights would be greatly appreciated as I have run out of ideas at this point.
Thanks for your time,
