Even though the units were brand new, I did have to do a firmware update on each of them, which added a minute or so per device to the setup time.
Once I had created an account with the required app, signed in via the app I had to download (kasa app) and entered my wifi password into this app (choose your security risk adventure yourself) everything worked well.
I used this to put a pair of lights on one plug and on the other I connected it to a woodburning stove fan.
Added both in a room, and customized the name for each item.
Adding them to Alexa was easy, after one item was added to alexa, (enabled in the Kasa app) after I initially added the second device to the kasa app, that named device was automatically added to Alexa.
transcript of my video review follows
(note I was a good distance away from Alexa device so when I have alexa turn things on and off, I had to turn my head to speak more clearly, which has nothing to do with these plugs and their app)
This is a 2 pack Smart Plugs they work with the Kasa app and they tell you to download that. In here they've got an on off button. I actually write that on the plug because months, years later if I move around or even if I move to a different house or something like that, it helps me to remember which plug goes with which app.
And so on. But about to get these set up. I'm actually replacing some others that from a different source that didn't make it possible to upload the Wi Fi when changed Wi Fi devices. Hopefully these will have some better options for updates. Got it all set up. App wasn't too difficult to connect to.
And had to do an update, firmware update. And then after that I was, I was able to connect it to the Alexa app. Alexa, turn off the front lights. Okay. Alexa, turn off the front lights. Okay. Alexa, turn on the front lights. Okay. I then set up the second one. It was easier than the first because the app already had my Wi Fi password.
And that's a warning. You will need to input your Wi Fi password eventually. Plus allow for a location setting. And maybe some scheduling type stuff, so consider that whether or not you want to do that. After all that, I was able to connect this to Alexa as well. The second one went faster than the first.
Alexa, turn on the stove fan.
Alexa, turn on the stove fan. And just getting ready to start a fire, so I got stuff in the wood burning stove, but I wanted to get the fan on the thing. Pretty cool that it works.
