You wrote "4 spots on a track in our living room also use them while the other 10 (on a different switch) are standard LEDs on a Lutron Dimmer." in post #37- what bulbs are you using?
More than one dimmer like this? Are you also using any incandescent bulbs on the same switch?
I used a Lutron in the same stairwell that flickers and wanted a timer in addition to a dimmer- that didn't work because the dimmer needed a slight draw, which the dimmer didn't provide- this was before bulbs and dimmers that can be controlled with an app without a hub or master controller (Radio RA, Radio Ra II or Caseta), or the variants from LeGrande, Leviton, etc.
Maybe the Lutron site has info about the bulbs that work best.
BTW- if you use these dimmers (which are definitely not inexpensive) with incandescent bulbs, pay attention to the Wattage of the bulbs and if more than two dimmers are in the same junction box, you would need to de-rate the Wattage load because the Aluminum fins need to be removed to get them to fit a standard Decora wall plate- the fins are used as heat sinks.
You are right, dimmers in general are not simple at all. When I did our lake remodel in 2005 to 2006 I used dimmers with incandescent bulbs. Boy, did I get an education about dimmers in a hurry. Major issues through dumb ignorance, and a big re-education.
Then when I converted the home to LED, I got a somewhat extended education, but I was primed by my first encounter.
When we built out home here in 2019, I can say I was armed with a fount of knowledge about the problems. So I was able to guide the electricians and builders to engineer it right. The electricians in the end just asked me to order the products. I am glad to report, that experience in the world of hard knocks allowed for the design of a system that has worked really well and been reliable.
In all this, I have to give a shout out to the engineers at Lutron, who went out of their way in their guidance and very much assiated my education in a selfless patient way.
So anyone who thinks it is a slam dunk to install lighting in a high end home, especially if it also has complex AV equipment, then you need to think again and again. If you don't do your homework you will get lost in the weeds and have a poorly working system and likely RF interference issues.
One issue I should mention that we did have with this home was one that was not my fault, but I should mention this, if you are having trouble with dimmers causing flickering.
Light dimmers do not like being on the same circuit. If they are then flickering and blatant flashing can occur.
I specified all dimmers be on their own circuit. In our family room the dimmer is on the opposite side of the same wall to one of the dimmers or the staircase lights.
If both dimmers were active, then we had a bad flickering issue. So I asked the electrician if he had separated the circuits. He confessed he had not, as he could not see the point of running two lines back to the panel when the dimmers were opposite each other. Anyhow I made him go up into the roof space and run another wire back to the panel. Problem solved and a learning issue for that electrician.
