Pros
Pro Very configurable thanks to IFTTT
IFTTT (if this then that) allows you to set up conditional automations. So you can turn on or off devices attached to the switch based on conditions like time of day, your location or any trigger from 300+ services.
Pro App has a simple button widget
Pro Integrates with Google Home
Pro Easy installation
The installation instructions are fairly basic - just connect to the switch's Wi-Fi, go into the WeMo app, make the connection, and then swap over to your regular Wi-Fi (if it works the first time).
Pro Get notified when the switch is activated
You can set up the Insight to send you app notifications when the switch is turned on or off based on set rules. So you can, for example, get notified only between 9am and 5pm while you are at work, and turn off notifications while you are at home.
Pro Good companion app
The WeMo app is simple to use, and provides quite a bit of information at a glance as well. There's a large power button to open/close the switch, as well as a timer which indicates how long the switch has been on for. It also shows data such as average on time each day, average cost and more.
Pro Can send reports about energy usage
You can get on demand reports of energy usage as well as set up Insight to email daily, weekly or monthly reports of energy usage.
Pro Scheduling allows switch to operate automatically
Scheduling can be done on either a weekly basis (same schedule for the whole week) or you can configure each day individually (e.g., the weekend can have a different schedule than the weekdays).
Pro Integrates with Alexa
Through Amazon's virtual assistant Alexa (found on the Amazon Echo ling of products) you can control the switch via voice.
Pro Third party hardware integration
WeMo is one of the leading Internet of Things ecosystems, and can integrate with a wide variety of other products that also support the WeMo standard.
Pro Support for rules
Rules determine when your lights are on and off (think of it like scheduling for events instead of times).
Pro Automatic overheating protection
Inside this smart switch is a sensor that detects when it is getting too hot. It is user adjustable, allowing you to lower or raise the temperature threshold if you choose. If the device turns off due to heat, it will send a notification to your phone.
Pro Very easy setup
The setup is a breeze - it even includes a WPS button on the side for dead simple connecting. If your router isn't WPS compatible however, the setup is still easy. Just hook your device up to the plug's Wi-Fi network, go to the app and enter the code found on the back of the plug itself (write this down beforehand so you don't have to unplug it half way through to check). Then, hop back onto your regular Wi-Fi and login (or create) a My D-Link account.
Pro Android and iOS compatible
Whether you have an Android phone or an iPhone, this smart plug will work. That makes it especially easy for households that have different mobile users living under the same roof - anybody can turn the switch on or off regardless of which mobile phone they choose (so long as it isn't a Windows Phone or old BlackBerry).
Pro Integrates with Amazon's Alexa
Alexa is Amazon's personal assistant that comes with the company's smart home products, such as the Echo and Echo Dot. These are always listening devices that allow you to control certain aspects of your life without lifting a finger.
Pro Works with Apple TV
Pro Scheduling support
Through IFTTT, you can create very detailed schedules for when the switch will be turned on or off. This schedule can be different each day of the week, and you can have it turn on and off multiple times each day if you choose.
Pro Works with other D-Link devices
D-Link offers a number of smart home products whichinclude cameras, water sensors, plugs, baby sensors, sirens, and motion cameras. All of these products are designed to work together.
Pro Built-in IFTTT support
IFTTT (IF This Then That) allows you to create your own custom 'recipes'. Triggers can be as simple as time of day, or your location, or as specific as receiving a text from a specific contact to when your favourite team scores a goal. IFTTT is easy to setup, and allows for cusomtomization far beyond what manufacturers regularly allow.
Pro Can track energy usage
The energy data is collected and displayed in handy graphs that review the last month, 3 months, or 6 months of usage. This allows you to easily view the change in power consumption between seasons, and can help identify areas where it could be beneficial to turn the device off.
Cons
Con Poor Android app
The in-app performance is poor - it lags and studders. Performing any actions takes a couple seconds to register, and the overall experience is bad. This could be due to the Wi-Fi connection, or it could just be a poorly optimized app.
Con Buggy setup
The setup process sounds simple enough - connect to the switch's Wi-Fi network to pair, and then swap back to your regular Wi-Fi. In practice, the connection is spontaneous. It takes a number of tries to set up the connection successfully.
Con Power button can be distracting
When the switch is on it illuminates the power button which can be distracting. Especially at night or when watching a movie. And there's no way to turn off the power button without turning off the switch.
Con Blocks other plugs
This switch is compact as far as smart switches go, however it is still large enough to block the other outlet on a typical 2 slot wall outlet.
Con Works only with devices that use more than 2 watts of power
Con No yet compatible with SmartThings hub
SmartThings is Samsung's smart home ecosystem. The WeMo Insight isn't compatible with Samsung's software.
Con No HomeKit support
Con Lights are always on
There are 3 lights on the front of this plug - the first is the Wi-Fi indicator. It lights up green when the connection is fine, and yellow when it isn't. The light to the right is the status light which lights up green when plugged in and ready to power devices plugged into it. The last is the power LED, located just below the power button. This light shows whether the plug is outputting any power at the time.
Con Bulky
The plugs are near the bottom of the device, which means that if you plug it into the top wall socket it won't cover the bottom socket, although it will stick up above the socket and create a noticeable eye-sore (especially thanks to the always on lights).
Con No HomeKit support
HomeKit is Apple's ecosystem that is just starting to step into the limelight. It has deep integration with Siri, and allows multiple actions to be taken with a single command (once configured properly).
