Zwave Switch to Control Zwave Outlet


(Matt Lehmer) #1

First off I am VERY new to this and have been reading on different things to connect for a few weeks now. In my bedroom I have a light switch that is by the door that controls a single outlet just below it. Problem is the 2 lights that I control with this (bed lamps on either side) are on the opposite side of the room. I am trying to figure out if I install a Zwave switch in place of the current outlet, can that be used as a trigger to turn on a power outlet on the other side of the room? I’m thinking of either a relay or a smart switch that plugs into a hot receptacle. Any help would be greatly appreciated.

Yeah… add a Z-Wave outlet at the remote location and use the Big Switch SmartApp to control it from the switch.

Aeon makes a micro switch that fits inside the gang box, turns the outlet into a smart one.

If I understood your setup correctly, you have one outlet and 2 lamps. Probably an extension cord running to the far side of the bed for the far side of the bed.

You can install a plug in z-wave outlet into the existing outlet, plug both lamps into the one extension cord, and control both lights at one time. As long as collectively they don’t exceed the rated capacity of the module.

As an alternative you could install connected lights in the two lamps such as the Cree connected bulb and be able to control the two lamps as individual entities. If you want to control both only as one entity, there are options for that too. This option does however give you some added flexibility to turn off one bedside lamp and leave the other on. I do this at my house while the better half reads at night.

In short you can choose the option you prefer. There is always more than one approach in SmartThing to accomplish what you want.

The cost of either option is about the same about $30.

I have a similar setup in my master bedroom. I replaced switch with a Zwave switch and then replaced dumb duplex receptacles with GE Zwave outlets that have one switched plug. Then I created a Smart Lighting rule to turn on the Zwave outlet when the switch is on and off too. The advantage of Smart Lighting is it runs local.

perfect, that is exactly what I needed :slight_smile: Thanks for the help!

Ok, please correct me if I’m wrong.

You have a dumb outlet that can be turned off by a dumb switch?
You then replace the outlet with a smart switch.
And…
You replaced the switch that controls the now smart outlet with a smart switch?

If that is correct? Why did you waste money on two devices? When you only needed one?

Valid question but don’t worry I am not as dumb as these outlets and switches. :grin:

The smart outlets are for lights NOT controlled by the switch. One of my nightstand lamps is controlled by the switch but the other is not and I also control a lamp across room on my dresser. I have a similar setup where my master shower light turns on my hot water circulation pump across the house in my garage.

I am not an electrician by trade but have rewired a lot of my house and this setup has enabled me to control things that I couldn’t physically wire together.

Gotcha… The way it read it sounded like you were turning the smart outlet on and off with a smart switch… I was thinking… Um dude… That’s overkill! Lol

The hub is the middleman

You probably already know this, but just for clarity: the smart switch communicates directly to the hub. The hub then sends the messages to whatever devices you wanted to control.

So you can have an on/off zwave smart switch in the upstairs bedroom control zwave lights in the downstairs laundry room, or zigbee lightbulbs, or a WeMo pocket socket in the hallway, or all of the above as a single group because all the bedroom switch has to do is talk to the hub, and then whatever smart app/routine code you are using will handle getting the messages to all the other devices.

Since all of this is done wirelessly, The physical location of any of the devices, and the communication protocol they use with the hub, don’t matter. :sunglasses: This is one of the most powerful features of SmartThings’ multiprotocol design.

So first set up the lights to talk to the hub

For that reason, as others have mentioned, all you need to do is decide whether you want the two bedside lights to always go on and off together or whether you want the option of independent control.

Then you just use whatever wiring/devices you need to get the bedside lights controllable by the hub. ( there are several ways to do this.)

Once the hub can control those lights, a smart switch can ask the hub to control those lights, and you are all set.

the double tap switch feature

By the way, one feature that some people like while others find confusing is “double tap”. This is where tapping on the light switch once tells the hub to do one thing, and tapping twice tells the hub to do something else.

This is often used for groups of lights, where tapping once turns on a single light and tapping twice turns on all the lights in the room.

Although you will find some people trying to do this just with code, that method doesn’t work very well because the timing on communications with the smartthings cloud can vary and capturing the taps requires precision timing.

However, homeseer recently introduced a line of switches which can do both double and triple tap quite well. The tap pattern is recognized by the switch itself and then it sends a different numeric code to the hub. Since only one message is being sent to the hub whether it’s a single tap or double tap, lag in cloud communications isn’t the same problem. At the present time this is the only switch brand with this feature.

I just wanted to mention it because it is an option that some people like for the type of use case you describe.

The wall switch is still an intuitive switch as far as just as whatever you set up for the single tap option. But you do have to explain the double and triple tap to people before they can use it.

The better way to do this is with states and not timing. Press on once for the last on state; press on again for the next… etc. In this manner you can have as many states (scenes) as you want without having to worry about timing issues.
