I am a real novice diy'er - 20 years ago moved into a new house and had an HAI omnipro system for most of the lights installed. I have a hallway that has 3 different switches that can turn them on/off. Yesterday noticed that all the lights were out - thought it was bulbs but when new bulbs didnt work - checked breakers - which were fine - went to my hai touchscreen - and was able to turn the lights on. but cannot seem to turn them on from the switches. i did turn them off from one of the switches. Is it likely that one or all of the switches are dead? the light is still blue in 2 of them but no light on the 3rd - does that indicate the bad switch. (That was the switch that turned the lights off). Also - if I just buy 3 new switches - what do i have to do in the system to add them to the software? I've never messed with adding units - only doing the programming for on/off etc. I am using PC Access version 3.11.4.697. I am not in a position to upgrade the whole system so whatever is the easiest/cheapest band-aid is what I will do. Thanks in advance for any and all advice and guidance!
