I did my research and bought the newer GE/Jasco Smart dimmer switch from Lowes (works with Iris) that has a neutral because I have low load LEDs in a number of spots.
My first install on 3 CREE floods went beautifully and worked exactly as expected, on/off/dim. However every other one I’ve installed with all 4 attachments (line, load, Neutral, & ground) is not! They only function like on/off switches in person and are even seen in Smartthings as non-dimmable. What is going on?
I called the company and they said maybe the ground isn’t really grounded. My electrician came and said it was grounded. (He by the way had no idea how the switches worked at all). Then Jasco said maybe there was “noise” in the line. What do I do about that?
And any other suggestions about what to do in the older part of the house that doesn’t have ground OR neutral wires in the boxes?
I just want it to work! Thank goodness the first one gave me some confidence or I would have probably given up already.
