@Prl519 I thnk this is a great idea!  Amazon had their buttons that would allow you to control routines but they are no longer being made.  Samsung Smartthings has their button, but it does not work with the Deco smart router app.   
 

I like this idea!

@Prl519 +1 for this! I'm in the process of switching from Lutron to TP-Link devices/switches, but the one thing that I'm missing is a TP-Link version of Lutron's Pico remote! I reallllly hope TP-Link offers something like that ASAP as I'll be the first one to order it :)!

One thing I discovered trying to use a Kasa wall switch as a "virtual" remote switch (it's not connected to any physical load) is that it doesn't always know the on/off state of the remote device it's controlling.

I have a wall switch configured to remotely control a table lamp that is plugged into a Kasa smart plug.  The plug itself is under the table, so I can't use the on/off button on the plug itself to turn the lamp on or off.  Instead, I use Alexa or the remote wall switch turn the lamp on or off.  But if I use Alexa to turn the lamp on or off, the wall switch doesn't "know" about that change in the lamp's state. So the illuminated white circle on the rocker switch may not "agree" with the current state of the lamp.  The result is that pressing the rocker switch may turn the lamp on when it's already on, or turn it off when it's already off.  The "fix" is to simply press the switch again.

This is further complicated by the fact that there's a noticeable delay using the virtual remote feature, since the signal to turn on or off the controlled device(s) must get sent, over the internet, to your Kasa account, and then routed back down to the device(s).  In my case that delay is about 1-2 seconds.  So if I press my virtual wall switch to turn my table lamp on or off, it takes a second or two to see if the lamp changes state.  If it doesn't (meaning the switch and smart plug are out of sync)  I have to press the switch again, resulting in another 1-2 sec delay.  Certainly not "instant" as would be the case if the wall switch were directly controlling the lamp.

A Kasa hub controller would solve this problem (the hub would know the state of every defined device, and could communicate that state with every smart switch or plug), and eliminate the delay described above, but not requiring a central hub is one of the best features of Kasa (keeps the cost down and the configuration much simpler), so...

@Prl519 

How did you configure the switch to control the plug?

Just ordered one and tried ... Can't find this option.

Help would be apprichated!

Thanks

It's done using Kasa's Smart Actions feature.  You'll find the Smart Actions icon at the bottom of the Kasa app's screen.  Click on it, then click the '+' icon to add a new action.  You'll have four action choices: Motion Sensing, Control with a Switch, Schedule a Scene, and Auto-Off Timer.  Select the Control with a Switch choice.  Then select your switch from your list of switch devices.  Then select a device or group of devices you want to control from the switch.  Finally, give your smart action a name, like 'Control LR Lamp'.

I use a smart action to allow the wall switch that controls my front door light to turn on and off all of my outdoor lights.  This is very convenient as I can now turn on and off all of my outdoor lights from that one switch.  That gave me the idea that I didn't need a switch to be wired to any device; I could just wire it to power and neutral, and then use a smart action to have it control any device(s) I want.

Hope that helps.

@Prl519 

Super! That works great  Not sure why I did not see it 

@Prl519 I completely agree there should be switches available for the plugs! Im in the dilemma now that my bedroom switch controls only the plug directly below it, but our light needs to be plugged on other side of room so we walk across a dark room to push the button on actual Kasa plug, or use the app to turn on (when we remember to have our phones with us)

@MamaRita 

Well, you can use a switch and configure it in a group. That will do the job. 

You can use any Kasa light switch to switch a Kasa plug or another Kasa Switch. 

I use it as a "wireless 2 way switch" to switch a dimmer switch on the other side of the room.

BUT IMPORTANT!!!   The key is that you need a ballast on the "empty" switch to make it work.

I got this one and it just works fine: https://amz.run/4xeH

@MikeSun so you're saying : I need a Kasa switch for the outlet by my door - but if I don't plug anything into it I need the ballast like you recommended ... once that is all set, I can use the switch by my door & setup a group with the kasa plug controlling my lamp?
