Hi Michael,
That worked. I had been using the "Add INSTEON Device" menu option from the pull-down, but had been doing the "Auto Detect". When I specified Keypadlinc Dimmer as the device type, everything fell quickly into place - all of my KPLs have now been added.
I suppose that I was "lucky" to score four of these tight-lipped V1.6 KPLs
Do you know if there are any other gatchas that I can expect with the these V1.5 and V1.6 KPLs? Or, is the lack of the IDReq only significant during the initial discovery?
Thanks for your help,
Paul
