A couple weeks back my Insteon network failed -- sort of. Devices were still reporting status to Indigo but I could no longer issue commands to remote Insteon devices from Indigo. (I also have a LOT of Z-wave and it is working just fine. ) Sending commands from Indigo to an Insteon device always has the same result, "no ACK received." So it appeared that the 2413U was receiving but not transmitting. Things I then tried:
1. reset and resync the interface. No success.
2. factory reset the 2413U, reset, and resync. No success.
3. Call Smarthome, do everything they tell me (that I have already done), and get them to send me a new 2413U.
4, Install new 2413U, reset to factory defaults, and resync. No success.
OK, now I am at wits-end. Suggestions?
