Would appreciate any help. I have an existing 3 way light switch in a stairwell. Currently, there is a dumb light switch downstairs and a dumb light switch upstairs. See DIAGRAM for how it is currently wired. Does not appear to me that there is a neutral wire in this set up. I have an Inovelli Dimmer (Black Series - Gen 2) to install in the UPSTAIRS SWITCH and a GE Aux Switch to install in the DOWNSTAIRS SWITCH.
Here is the current wiring that works for the dumb switches:
I have tried this wiring (ATTEMPT #2) and it does not work (*the DIMMER works but to the AUX switch does not work at all): [NOTE: forgot to draw WHITE WIRE to TRAV in DOWNSTAIRS SWITCH in this diagram - please assume that is where it is]:
I am not an electrician. But I have installed several other switches (and 2 3 ways with different wiring) with success using Inovelli switches. I would very much appreciate help on what I am doing wrong. Of course, if more info is needed to assist, I would be happy to provide.
Here is the Inovelli drawing and you have replicated that, I think.
In the top Inovelli box, remove the white from the 2-wire coming from the light so it’s not connected to anything and USING A METER test between it and the ground. You should get a constant 120VAC. Just for completeness, test with the other switch in both positions.
What hub are you using?
Did you set the parameters for non-neutral and 3-way toggle?
Thanks much for your time and response. I am using Hubitat. I have not tried to add the dimmer to Hubitat yet and have not set any parameters for the switch. Do I set those parameters using the switch before the 3 way will work with the GE AUX switch properly without a neutral?
Glad to help. Those settings do need to be made for the Aux to function properly. I’m pretty sure the Inovelli defaults to a neutral installation and single pole. You can set those at the switch so you don’t have to add to the hub first if that’s your preference.
I’m also hoping you didn’t smoke the switch by putting 120VAC on the Load terminal. (#2) Not saying that’s what would happen, but the switch isn’t designed to work that way.
You sir, are a saint. Set it up (had to use the settings in Hubitat as the at-switch settings didn’t seem to work). All is well and working. Thanks you. I will buy you a virtual beer for the trouble!!
