Admin Console keeps giving me a "Failed Communication With" for a insteon device. When I OK it, I get it a second time. After that I can control (manually or via program), and restore it with no issues.  Happens for same device every time I start the console.

Any thoughts?

I have a similar situation.  I believe the one device has communication issues that come and go because of some unknown interference source.  So the error message is in ISY from a failure prior to opening the admin console.

Looking back I am thinking it started when I had the device unplugged when starting the console. Now it keep coming up every time I start the console but never when being used.

Did you try rebooting eisy/polisy?  I had issues with other pop-up notifications presenting with every instance of opening the admin console after adding a new insteon device.  Every time, it would tell me I had successfully added that device.  Rebooting got rid of it.  Though for all I know, if I add another insteon device it will happen again.  Don't know, haven't added any since then.

Right click on the device in the device tree and select "Restore". There is likely a link missing yet. Devices have a link to the PLM for every function, sometimes 10 or 12 links. They can all work properly except one at times.

Thanks to you both. The reboot resolved it!
