Running Indigo 7.1.1. Running MacOS 10.13.1.
It being time to get the Christmas lights up, I tried to add the LampLinc 2457D2 dimmer module to control the tree lights. Also tried to add in a pair of 2634-222 outdoor on/off modules to control the exterior lights. All of these modules works just fine last year.
Now I cannot add in these modules.
No matter how I try to add them I always get a "device not responding error". In the mean time, other existing modules work fine. I am able to operate Insteon devices that were working before.
I tried disabling and re-enabling Insteon. I have also tried power cycling the 2413U. No effect on adding new modules.
Not being one to leave well enough alone, I tried resetting the 2413U. I unplugged it, held down the start button, plugged it back in, and continued holding the start button for 10 seconds. The end result is that I can no longer communicate with any of my previously-installed-and-working Insteon devices nor can I add&sync with any Insteon devices, old or new.
Indigo seems to be able to talk to the 2413U. In the interface status display the PowerLinc 2413U shows up green. It seems to act like it is sending messages. (I see the status display show the outbound messages. I see the green LED on the 2413U flicker.) It just never seems to get a response.
This does suggest to me that something is wrong with the 2413U. Any suggestions on further testing/resetting?
Thanks.
