As introduction, my house of 1950’s vintage, had the«state of the art» lighting system, where a low voltage system powered the light switches, which controlled relays that would open or close a circuit to fixtures in ceiling boxes throughout the house. Included were two master control panels at either end of the house that could turn lights on/off. The light switches have 24 volts power, while the ceiling boxes have 110VAC. In 2007, I had my roof replaced – it is a flat roof. At the time my lights failed, either a great coincidence or because one of the roofers’ nails had pierced and shorted the low voltage system. I called Star Electric. They spent a lot of time and got 6 – 7 lights out of 40 working. The roofers even pulled up a section of roof and replaced it. I had no idea what was going on. After a few months those 6 – 7 lights stopped working. Since that time, I concluded that Star Electric also had no idea what the problem was nor how to fix it. I was not going to call them back. Star billed me for ~$ 900. They didn’t care that they hadn’t fixed my problem. They were like attorneys or doctors who bill you irrespective of the outcome. My problem was resolved after a consultation with Frank Gordon Electric. fRANK is damned busy, but when I finally found him, Frank said I could, at great expense, have the roof torn up and have the system rewired, or go with a wireless solution. That solution included Leviton Levnet wireless self-powered switches and ceiling box mounted receivers as well as motion activated switches. I have installed both and the result is uplifting. I placed Heath/Zenith motion activated switches(Home Depot $ 20) to activate fixtures in the halls of my house – they flip on as I enter each hallway – these also have an option that, after dusk, turns them on dim when not activated. In sum, if you want intelligence for a difficult issue, you want Frank Gordon Electric, NOT Star.
