Need Help! Complicated 3 Switch Circuit

Your diagram doesn’t match your verbal description, and I’m not sure you understand how the traveler system works. Did you take pictures of everything before you disconnected the original switch? Also, was your original non networked set up the kind where sometimes you flipped switch B up to turn on the light and sometimes you flipped it down? There are about 8 different ways to wire a nonnetworked 3 way and not all work for networked switches. So the first thing an electrician would figure out is exactly how the old switches were wired.

The fact that you can’t turn off the lights from what you’re calling the Master when the Aeon switch is on indicates either you have the aux and the master confused or it’s not wired correctly.

  1. makes sense from your diagram except I doubt if your diagram actually represents what’s happening inside your walls. Remember that a networked switch must always have some current or it won’t be able to hear the next “on” command. This might help:

Wire colors can be completely arbitrary, you never know what the previous person actually used. The connector colors are more consistent in their significance, but you haven’t mentioned those.

All of that said, don’t connect the green wire to the neutral unless an electrician tells you to. (And that electrician is not a beneficiary in your will. Or having an affair with your wife. :wink: ) Ground and neutral are not the same thing.

If you live near a Home Depot, many have one day classes in how to install a light switch. That would be a good place to start. Otherwise bring in an electrician.

Do what @JDRoberts suggested also remove the aeon micro switch or the master dimmer asap. It’s not meant to be control by another dimmer switch. It will get damaged. Green usually is ground. Not neural unless it’s bonded at the breaker and check by an electrician.
There are a couple of posts on the forum about the aeon micro switch. Take a couple of pics of your old wiring and confirm your wiring and we will be glad to help.

@Navat604 ,

Good catch, I missed that the OP was trying to use the dimmer version of the micro switch in the aux! You’re right, of course, that shouldn’t be used with another dimmer.

Thanks @JDRoberts and @Navat604. I’ve removed the micro dimmer and will use the standard (non-dimmer) Micro Switch–I’m assuming that is okay?
I also appreciate the clarification on the green wire being ground and not “neutral.” I won’t attach it (thanks for saving me from myself). I was looking at a diagram from another support forum and somebody had it winged to a “white wire,” so I foolishly assumed I should do the same. I guess I shouldn’t copy everything I see posted.

I’ll swing by Home Depot today for a crash course on 3 way… I feel like a complete moron… clearly I need some education or I’m going to burn the house down. :disappointed: : I did all my 2 way switches without any issues–I hate 3 way.

To answer your questions:

Yes, just as you described–it was an alternating 3 way that depended on the position of the other switch.

I didn’t–but I could recreate and/or describe. I have a very vivid memory and remember exactly what went where–there are 4 holes on what I think is the “Aux” On/Off Switch. The bottom right (with the black screw) had the black wire, the top left had the white wire, and the top right had the red wire. I then foolishly went by the colors from the Aeon Instructions–i.e. assuming the red was the load, the black AC Live coming in… which now I see was wrong-headed. Although it’s confounding how the light could be turning on if I put anything but the “Load” into the Load L section of the micro switch.

So unless I’ve got the Master and Aux flipped, maybe the red & white are the travelers and the black is carrying the load to the light? *I do think it’s unlikely I’ve got the Master/Aux flipped because the Master has Power after I disconnect the Aux, while the Aux only gets power when I have the Master connected…

Perhaps someone spliced the travelers and changed colors at the light box? There are 6 lights in the kitchen connected to these switches.

Thoughts?

Thanks,

Wanted to follow-up and close this out. I solved it a few days after the post. Thanks for the help.

I want to share my contribution with the community as this solution resolved my problem. I have working device handlers for Aeon micro switch and Aeon micro dimmer. They’ve been working great in my home for last 7 months. You can download them from here: https://github.com/northam/smartthings
You will need only these two files: aeonDimmer.groovy and aeonSwitch.groovy.
These drivers address the most important parameters to make them work as “normal” switch and “normal” dimmer.
