A few weeks back, one of my Switchlinc V2 dimmers started to respond to all device commands in that the attached load (in-ceiling recessed LED lights) blinks off and then on when another device in the network is controlled. At first I thought it was being caused by an unexpected link on a keypadlinc or similar, but have since determined that any Insteon activity causes the blinking activity. In fact, I can send a command directly from Indigo to another device and the Switchlinc will again blink the lights (although I don't see any activity related to the Switchlinc in the Indigo log). Dimming another device is particularly annoying as the lights in question blink on and off as the dimming occurs on the device being controlled. This problem only occurs when the load on the Switchlinc is in the ON state.
To troubleshoot, I have reset the device several times and tried resyncing links to no avail. Most recently, I removed the device from Indigo and then reset the device and re-added it to Indigo. Both local and remote control of the device work fine, but other network activity still causes the device to blink.
I have never seen this before and wondering if the device is simply on its way to failure? Before replacing, is there anything else I should try?
Thanks!
