8-way smart switch


#1

I have a lighting circuit in my kitchen/mudroom area that has a total of 6 switches for an 8-way configuration. I have used the GE/Jasco switches in a few other places in my house. The specs for the 14294 say that it can take a maximum of 4 add-on switches for a total of 5-switch circuit. Has anyone tried additional add-on switches beyond the four? Does perhaps having rhe master switch in the middle of the string of switches make a difference? Am I SOL with this many switches?

Thanks in advance!

You should not add additional switches to a GE set up.

However, if you use a different brand where the auxiliary switch can communicate directly to smartthings, you could certainly create a virtual –Nway with as many auxiliary switches as you like, since each Switch is going to talk to the hub and then the Hub will send a message to the master.

The linear/gocontrol brand is popular for this. You need one master Per circuit (it wasn’t clear to me if the mudroom and the kitchen are on the same switch or not) and then one accessory switch for each of the auxiliary positions.

Although the manufacturer will discuss a limit based on direct Association , in a smartthings set up you’re not going to use direct association for this, so you can actually have more auxiliaries if you like.

Shop around, including at Home Depot, because prices do vary:

Master:

Auxiliary:

So I don’t think you can do this with the GE brand, but you should be able to do it with Linear/GoControl or Cooper.

Do what? 6 switches control the same light or set of lights?


#4

That’s right. 6 switches controlling a single set of lights.

Thanks. Sorry for such a basic question. Is it possible to use 5 of the GE switches, and since it would be virtual, add the linear for the 6th? Is the virtual association in smartthings accomplished in smart lighting? Do I need something like Core?

I really appreciate the help.

Wow!! That’s a lot or ways!!

Maybe, depending on your wiring layout, consider using a Fibaro Dimmer 2 module.

When combined with momentary switches, you can have an almost unlimited string of switches.

Also, buying a single Fibaro module will certainly be a lot cheaper and easier to install / maintain, compared to 6 smart/add-on switches.

Have you looked into these Zooz switches that work with regular 3 way switches (not sure of limit)…

That must be a big room!

Probably, but there are two separate issues with this.

First, you can add an additional auxiliary at anytime anywhere if it’s using the virtual N-way method. Regardless of whether there are other wired auxiliaries or not. Since it has its own radio and it talks to the smartthings hub directly, it doesn’t matter what else is talking to the master. So that part is good.

The second issue has to do with the specific wiring at that particular location. Your existing wiring might require that a device at that location be wired into the circuit loop and then it can get a little more complicated. If you were going to make all The auxiliaries virtual, it’s easier in the sense that you just don’t use any of the traveler wires, make the master independent, and then wire each auxiliary separately. But if you going to loop some of them it can get complicated. So it will just depend on the actual wiring. But in general, providing you have the right device model at each location, you should certainly be able to have some auxiliaries which are using traveler wires and some which are communicating directly to the hub instead. People often use this to add an additional auxiliary switch in a different room on an entirely different circuit, for example.

Is the virtual association in smartthings accomplished in smart lighting?

That’s one way to do it. You just have One switch “follow” the other so that when switch A comes on, switch B comes on. A lot of people set up a mirror so that it’s also true that when switch B comes on switch A comes on, so the statuses stay in sync no matter which which you physically press. (This mirror doesn’t usually create an endless loop, it depends on the exact model of device being used. But typically if the second device is already on, then the command is not sent so the loop stops.)

Do I need something like Core?

No, although you can do it with core or webcore if you want to. :sunglasses:

The main limitation is that with the way the Zooz switches wire now, when having 3 or more switches in your set-up, it’s necessary to have both line and load in the same box for the installation to be successful. With 2 switches (3-way), you can wire the switches in both cases (with load and line together or separated) as long as there’s neutral present.
