I currently have 1 Inovelli White Dimmer in my smart home, looking to add a few more. My basement has 4 light switches. Switch at the top is a 3way with 1 at the bottom (which controls 2 cans/retrofit LED). Next to the 3way switch at the bottom is single pole (connects to 8 cans/retrofit LED). And the third switch elsewhere controls I think 4 sconces.
My question is, would I get 3 dimmers plus the Aux Add-on switch? And the Aux add-on would go at the top of the stairs?
I have some Lutron switches in my home as well. But when I was going to install it at one end of a 3way, was advised from them not to, because we discovered it might be a dead end. I think that’s what it was referred to as, though I cannot find the documentation. That one was put in a different 3way switch upstairs and it’s working just fine.
Yes, one dimmer for each switch leg you mentioned, and the Aux for the 2nd switch in the 3-way.
You’ll have to look at the wiring in the multi-gang box at the top of the stairs. Since you have two 2-way switch legs in that box, there is a good chance the power originates there. If that’s the case, the dimmer would go there and the Aux downstairs. But you really have to open up that box and look, because until you do, you really don’t know how it’s wired.
To get a better understanding of the wiring, take a look at the Inovelli wiring diagrams:
Sorry I wasn’t more clear, it’s a single switch(3way) at the top of the stairs, bottom of the stairs has a 2-gang box, one of which is the other end of the 3way, the other is a single pole switch.
The simple answer to this is yes, you can, but there may be a few caveats.
Depending on your wiring, if the downstairs end of that 3-way circuit is a dead end 3-way, then you would have to utilize the no neutral wiring method (whether you have a neutral available or not), which may end up requiring extra hardware as you only have 2 LEDs on that switch… In a no neutral set up, the switch pulls the power it needs through the Load wires instead of the Neutral wires, so the more of a Load there is on the switch, the more current it has the ability to pull. With only 2 LEDs, it may or may not have enough of a Load and may require a bypass installed, usually at the light (but might be possible to install in the same box as the Aux switch if there is room and a neutral).
The same is true if any of your other circuits do not have neutrals to use, but with 8 LEDs on one and 4 sconces on the other, it will likely be less likely that a bypass would be needed.
