Ranked in these QuestionsQuestion Ranking
Pro Easy to use scheduling
The scheduling feature is easy to use - select a time to turn on, and a time to turn off. You can repeat this schedule (called a 'rule' within the app) daily, or weekly.
There is also a built-in timer, which can be useful when you only need the lights on for a few minutes during an irregular time.
Pro HomeKit compatible
HomeKit is created by Apple, and provides easy control through Siri. Devices can be grouped together, and multiple devices can be activated at once with a single action (if you set up the proper scenes).
Pro Well designed app
The app is designed to look sleek, and give quick access to commonly used actions. Finding a specific device can be a hassle if you have many HomeKit devices connected in the same room as the lists scroll vertically, but this won't be an issue for the vast majority of users.
Pro Energy measurement
This smart plug will show you energy stats, which can be used to help determine the best way to slash energy costs. It does this in real-time in the app, as well as over time through a graph.
Con No Android support
Unfortunately, if anybody in your house uses an Android device, they won't be able to connect to the Koogeek smart plug.
Con No third party ecosystem integration
Unfortunately, it seems this plug isn't compatible with WeMo, Nest, SmartThings, Wink, or other home automation ecosystems. This limits the devices that this switch can connect with in the future (or the present if you already have non-HomeKit devices).
