Wiring Diagrams

Over the next couple weeks, I’ll be revamping the wiring diagrams to show a before and after so you can easily determine what setup you have currently and then how you’ll need to wire the switches moving forward.

Prior diagrams can be found here (On/Off or Dimmer), but will be phased out with the new diagrams shortly.

Below are the location of the new diagrams – let me know what you think and if there’s any that’s missing, please let me know!

@Eric_Inovelli - If I get on a laptop today I’ll look over it with more scrutiny. Mobile I had a weird blown up of one of the diagrams. All others looked like a good scale.

Perfect, just fixed it!

Is there any reason that the wiring diagrams don’t include instructions for the ground wire? My switch has a green screw for a ground connection but the installation manual doesn’t represent it or make any suggestion about what to do with it.

I can’t speak for why it’s not included in the diagrams, but my guess is that it just serves to confuse things. The treatment for ground wire connections is the same for smart switches as it is for dumb switches. To be honest, if you have to ask, you might want to consult with an electrician to insure that your installations are properly wired.

That being said, the switch needs to be grounded. This depends on the type of wiring used, but with Romex wire that contains insulated conductors and a bare ground, you should pigtail a bare ground wire to the bare wire bundle in the box and connect it to the green screw connection on the switch. To obtain a bare pigtail, cut a length of Romex and pull the bare conductor from it.

That ground is always connected to the green screw, period. It doesn’t vary, so it doesn’t serve any purpose to include in the drawings.


Great question - it was more to save the clutter of the drawings, but I will add a disclaimer on them to share this so there’s no confusion!

@Eric_Inovelli - It’s already in the manual under the Romex and tips and tricks section.

@Eric_Inovelli Looks like all the graphics in the links are broken…

Weird – it’s showing up on my end? What browser are you using?

I can send a diagram to you if you are looking for one in particular.

Sorry about that!

@Eric_Inovelli Hmmm…looks like it’s not a browser issue…I just opened the link on my guest wifi (insecure) and the graphics showed up. Looks like zoho.com (which is where the graphics are linked to) is on my routers bad site list.

These diagrams are really a nice addition. I plan to add two more Inovelli to a 4 way setup(already have one dimmer and two dumb switches). Just need to find time to cut power which also cuts power to my modem and router and I’ve got virtual learning teenagers that will scream when WIFI goes out. Anyways, I still have one question for a unique 3 way. You have diagrams for a neutral and also a non neutral setup. My first switch has a neutral and I have a dimmer installed. My second switch is what my electrician refers to as a dead three way because it doesn’t have a neutral. Does anyone think leaving the Inovelli as is and then adding a Homeseer as pictured with the no neutral diagram(pg 19) is reasonable and safe?
