I thought "oh no" I don't want to go through a replacement and re-syncing everything.
After the first time this occurred, I happened to plug the unit back in after about an hour and suddenly it was connecting and working again. Each subsequent time I've had the "can't connect problem", I've left the unit unplugged for 30 minutes or so, and then plugged it back in. Magically it's working again. Every time!
Yesterday morning Indigo sent it Power Outage email. Funny thing, I was at home and didn't notice any power glitches so I ignored it. Last night my wife mentioned that NO lights were on when she arrive home after dark. When I checked my 2413U the green light wasn't on. I unplugged and took it to another outlet thinking a breaker might have tripped. Nothing! However, as I wiggled it out of the receptacle I noticed a faint flicker of red and green from the LED light, but nothing seemed to help.
Resolved that it only lasted three years and I needed to order a new one I went to my back-up plan – the USB dongle (2448A7) I got two years ago come December.
Switched Interfaces to the 2448A7 and during the sync process received error after error after error message in the log. Found a post suggesting to Redefine the devices. Still no communications. My home automation is dead in the water!!!
Called SmartHome about the 2448A7 which should still be under warranty and they had no problem with doing an RMA and were even willing to cross-ship it so I could be back up and running tomorrow. (I'm in Ventura where 1 day delivery is likely.)
Before contacting SmartHome I wanted to see if there was something else I needed to do in Indigo to get the 2448A7 to work and found this thread in the forum. Hadn't gotten this far down the thread by the time I spoke with the SmartHome representative. When I read about the 2413U sometimes working again after being unplugged for a period I decided to give it a try, especially since I'd noticed those faint flickers of the LED. I plugged the USB cable into the interface, plugged the interface into the wall and the green light lit up steady as ever.
Switched interfaces and a new Sync and only got one error message. The device I'd tried to Redefine using the 2448A7 needed to be Redefined again back to the 2413U Interface. Did some tested from Indigo and at wall switches and everything worked as designed. I was very happy.
Lesson learned: First, try the leaving the 2413U unplugged for a period. Second, I had never tested my back-up, the 2448A7, so after the replacement arrives I will go through the arduous process of switching interfaces (and even redefining critical devices if necessary) to ensure it works before I really need it again. Third, it is probably worthwhile to have a spare 2413U on hand so I will keep an eye out for a good deal on one.
All of this is to say think you for your suggestion to leave the 2413U unplugged for awhile to see if it comes back to life after playing possum. Its gotten my home automation system back up and running sooner than I'd been expecting.
