I have just found out that we can only have 3 smart actions active. I'd just like to add my input to suggest that this limits the Kasa device(s) severely. As other users are pointing out, Kasa devices work well, but this limitation is not good. Please publish an update to allow for  more smart actions ... 50 would not be too many ... 100 or unlimited would be better.

@Carl I see this still an issue. I'll guess I'll return these smart plugs and get some that support more schedules... they seem to work great EXCEPT for that limitation....

@Carl  Alex and google don't support auto off. Samsung smart thing works though.

OK ... what about this ... I'll try to answer my own question ...

Using an Alexa Routine to Drive a Kasa Scene

Referring to this: https://www.amazon.com/gp/help/customer/display.html?nodeId=202200080

I have only basically tested this … however, it does seem to work. Don’t hate me if it doesn’t! Constructive comments welcome. 

For me to create Routines in the Alexa app on my mobile phone that will switch my Christmas Tree Lights (using a HS103 Smart Switch) as follows:

1. ON at 0700
2. OFF at 0900
3. ON at 1800
4. OFF at 2230

I executed the following steps:

1. Kasa App
   1. Add Christmas tree light device (HS103)
   2. Add a Scenes for:
      1. Christmas Tree ON
      2. Christmas Tree OFF
2. Alexa App (mobile phone)
   1. Go to the More menu icon (lower right).
   2. Select Routines.
   3. Select the + icon in the top right corner.
   4. Enter a Routine name:
      1. Christmas tree ON – Morning
   5. Next (top right)
   6. Select When This Happens, and then choose how to trigger the Routine.
      1. Schedule
      2. At Time
      3. Repeat Every Day
      4. At time 0700AM
   7. Next (top right)
   8. Select Add action, and then choose which action it completes.
   9. Under ADD NEW, select which device controls the routine.
      1. Smart Home
      2. Control Scene
      3. Select Christmas tree ON (Kasa skill needs to be enabled in Alexa!)
      4. ADD
   10. Review your settings (which can be changed later)
   11. Tap Create.
   12. Repeat for the related scenes and times:
       1. Christmas tree OFF – Morning using Kasa Christmas Tree OFF scene
       2. Christmas tree ON – Evening using Kasa Christmas Tree ON scene
       3. Christmas tree OFF – Evening using Kasa Christmas Tree OFF scene

@Carl 

Please pass on that we are returning our newly purchased plugs.  We just bought SIX new plugs to go with our first buy of 4 several years ago to manage Christmas light  We also bought two outdoor plugs.

Maybe I am missing something but that would be the ability to only turn three sets of automation on or off total.  So after I schedule my Christmas lights on, then off later in the night, I no longer can control an on and off program for my outside lights?

Software doesn’t take that long to update.  

I can't believe this limit too.

I just bought over 50 switches, power outlets and dimmers, and after paying to have them all installed this last 2 days, when I started configuring auto-off for a lot of things, I got this limit!

WTF?

If I knew it before, I would not buy it.

Now I'm stuck with this crap that will not do what I want.

A really, deeply disappointed customer...

:(

@BrzMan 

get the SmartThings app by Samsung. You automation problem will be solved.
