Is there any way to get WIFI devices, such as a plug, to list in ST? I currently have 3 WIFI plugs that are running off Alexa, but I would like to get them into ST somehow so I can include them in my automations, plus it would be nice to have everything in one place and feed to my ActionTiles.
Thank you.

It really depends what make/model the wifi plugs are.
Although they may not be officially supported there are a lot of guys on here that have created software to make different wifi devices run with SmartThings.
Someone may already have done the work for you
As long as they are on the same network as the hub, it should be possible. Also make sure you don’t have any form of client isolation on your WiFi as this will stop the hub from finding them.
Best solution would be to search the forums for the make/model of plug you have and see if there is a DTH for them, else post and ask if anyone has one.

TP-Link devices are already completed and running. Link below:
Belkin Wemo devices also have some integration. Main problem is determining the command structure for the cloud-based integration. Should be simple, however, simple is not a word understood by SW developers.
As others have mentioned, it depends on the specific brand and model.
Wi-Fi doesn’t have a fixed set of standard commands the way Zwave and zigbee do , so it’s not just a matter of being on the same network. SmartThings would have to know the exact message content that that particular device expects.
Typically you can get integration in one of five ways now and a future 6th, depending on the brand and model:
the future is coming: Matter
A) The home automation industry is very well aware of the frustration that consumers have trying to figure out what will work with what, and they are working on a new and very important inter-operability standard called Matter. All of the big companies are on board, including Amazon, Apple, Google, IKEA, Philips Hue, Samsung, Aqara, and a whole bunch more. (The notable exception being Tuya). Seriously, if this happens the way it’s supposed to, eventually the answer is going to be super simple: buy a model with the matter logo and it should work with SmartThings. 
And some of these are gonna be cheap generic Chinese devices. You’ll just need to look for the matter logo.
Consumer reports has a very good FAQ on Matter
But there are only a few of these available now. Leviton has one, Tapo has one, but there aren’t many. And you do have to have a smartthings/aeotec hub to use any matter device with SmartThings, so it’s not a solution for everyone.
FAQ: What do I need to add a Matter device to the SmartThings app? Do I need a bridge router device?
But I need something before Matter devices are available! Like, now!
OK, then you need to look into the following possibilities.
the device manufacturer publishes an “open API,” which is documentation describing the exact messages that their device expects. These are the manufacturers that want to encourage integrations, such as Phillips hue with their bridge. If the manufacturer has an open API, it will usually be described on their website, again because they are trying to encourage integrations.
The device manufacturer has an official integration with SmartThings. There are some of these, like iHome, Currant, Meross, TPLink Kasa, and Globe Electric. In that case, it will be listed by brand in the SmartThings app.
Smartthings will never see these directly.
Instead, you can create a “virtual“ switch to act as a proxy for the real switch.
Then you use Ifttt with four “applets“:
OK, that gives you a way to look at your smartthings device list and see whether the Wi-Fi switch is on or off. It also lets you turn it on or off from smartthings, because when smartthings turns the proxy switch on, Ifttt Will turn the Wi-Fi switch on.
This is the basic method for use with any Wi-Fi on/off device that has an ifttt channel.
And, yes, it’s a lot of work to set up because you need to create those four applets for every individual Wi-Fi device you want to control.
And it really only works well for on/off. It’s not very good for dimmers or for color changing. There may be some ways to make that work as well with a similar method, but it depends on the exact details of the device and it can be a lot of work.
If the Wi-Fi device has scenes that show up in its Ifttt channel, you might also be able to use those. But again, that varies a lot from model to model.
So that’s the basic Ifttt approach. Create a simple on/off virtual switch to stand in as a proxy for the Wi-Fi device. Then create four different Ifttt applets to keep your proxy device and the real Wi-Fi device in sync. 
Note that while Ifttt used to be free, as of September 2020 you will have to pay a monthly fee if you have more than three applets which means using this method will require a paid subscription with them.
In that case, you can probably get some integration through those apps. See the community FAQ:
FAQ: How does TuyaSmart Integration work? [Updated 2023]
If the device works with Alexa routines (not SmartThings routines), you can set up a virtual sensor in SmartThings and then use that to trigger the Alexa routine. The problem is if someone turned the switch off at the wall, smartthings won’t know it. ( that may change in the future as Amazon is adding new features all the time, but for right now, it’s a one-way integration)
OK, those are the fairly straightforward ways.
Other Options
Then, as has been mentioned, if none of those five are true it sometimes happens that a community member has figured out what messages the device is expecting and has set up some kind of integration. These often require a strong technical background to set up, and may require an additional “man in the middle” server like a laptop or a raspberry pi. ( or in the case of Sonoff – based devices, flashing the firmware to change it to something that is more compatible with SmartThings.)
To find those, usually the easiest way is to go to the quick browse lists in the community – created wiki and look on the “pocket socket” list in the device type handler section. If an individual thread is tagged " requires server" then it’s one of the ones that is going to need an additional server device and some programming skills.
You can also check the same quick browse list to see if there’s a simple integration that’s already been done. Or just search this forum directly.
FAQ: Using the quick browse lists without the community wiki
So it just comes down to the specific brand and model. 
If you already have an MQTT broker running, you can try the following
Or if you are willing to set up home assistant, that can sometimes be used as an intermediary, but home assistant itself requires additional devices and considerable technical skill.
2 of the plugs are Insignia NS-SP1X7. The 3rd I am not sure but can find out.
Everything is on the same home network connected through our AT&T router.
Again with Wi-Fi it’s not a matter of just being on the same network, you have to know the exact format of the messages that the devices will understand. It’s like the difference between being on the same phone network and speaking the same language. I might be able to call your phone, but if I speak Hungarian and you speak English we aren’t going to be able to communicate. 
Last I heard, insignia is a Best Buy house brand and doesn’t talk to anything else except Alexa. It might be possible to do something with Tasker and sharptools if you have an android phone. But if you have an iOS phone i think you’re going to be out of luck.
There are also, I’m not kidding, some people who’ve set up a cheap android device sitting next to their echo and automate the android device speaking command to the echo to get integration with devices that can’t be reached in any other way. But that’s a pretty hacky way to do it.
Looks like it’s easier to buy Z Wave plugs. Lol
Thanks everyone!
There are some Wi-Fi plugs that work just fine with SmartThings, it just depends on the brand and model. For example, the Meross MSS110HKKIT plug works and some people like those because they also work with HomeKit.
How about these plugs, will these work ON smart things app ?
IKEA TRÅDFRIWireless control outlet
Looks like the only thing these are missing is the power meter but at 9.99/ each… pretty good deal it seems like.
Those work very well with SmartThings and are very popular. However, they are not Wi-Fi plugs, they are Zigbee plugs.
Gotcha. What are the bottom line differences between the 2 types of plugs, smart vs wifi ?
Zigbee, zwave, WiFi, and Bluetooth, along with a number of others, are all communications protocols. So all those devices are “smart.“ For comparison of the ones that work with smartthings, see the community FAQ. It’s old, but it’s still accurate.
Also, I suggest you go to the quick browse lists in the community – created wiki, look down towards the bottom of that page for the project reports section, and then choose the first list, “get started.“ It should help answer many of your questions.
June 2019 Update:
If you haven’t bought the plugs yet, the TP Link Kasa line has an official integration now and is usually comparable in price and features to the other popular WiFi brands. You no longer need to use the more complicated community built integration, they should work out of the box now. 
They also support the TP-Link/Kasa bulbs. They do not support the following (at least not in lineup):
LB-120 Color Temperature Bulb
HS-110 Energy Monitor Plug
HS-300 Energy Monitor features.
I will depreciate my current support thread; however, I will still support the above three products.
I have two wifi smart plugs, Branded Wesho and Model S126.
These ones: https://www.amazon.co.uk/Wesho-Mini-WiFi-Smart-Plug/dp/B07M5ZMQYB
I’ve searched all the lists and can’t see any way of supporting these direct on ST. As I google I’m amazed how few results I get, which suggests it’s the same as a more popular brand, and whitelabeled… maybe. Anyone any ideas?
The typical cause of this inability is that no one has completed the integration with SmartThings and therefore the device will not directly integrate with SmartThings. Someone could write an IFTTT-based integration for these, but that has probably not been done.
