These great gadgets connect your old routine coffee maker, lamp, fan, appliances or just about anything else in your smart home for voice control and automation. There are models for each voice assistant. Some even work with all three: Amazon Alexa, and Google Assistant Apple HomeKit.

At only $ 18, this smart connector is the most accessible on our list. It is also the smallest. Pair this with power monitoring and Google Assistant and Amazon Alexa smartphones and voice control and you have a great choice for your outlet or smart home.

The SmartThings Wi-Fi plug-in will not work with HomeKit and there are no additional USB ports for charging. The SmartThings app (iOS and Android) doesn't offer as many customization options and scheduling possibilities as the Kasa smart jack from TP-Link above, but SmartThings impressed us by creating an easy-to-configure smart connector from your socket. which does not need a SmartThings hub.

This smart Wi-Fi connector comes with an easy-to-use application, monitors your energy consumption in kilowatts (kWh) and works with Google Assistant and Amazon Alexa for voice commands via the Wi-Fi router and Wi-Fi network.

The card's design blocks the sockets above or below it and is not compatible with Apple HomeKit. However, the Kasa TP-Link application is excellent and you will get a clear picture of how much power the connected device consumes.

Unlike some smart card manufacturers, TP-Link has a number of other Kasa smart home products, including light bulbs, cameras and even an electric tape, making it easy to extend your smart home in one application if you like this plug.

For $ 27, the Belkin WeMo Mini WiFi Smart Plug is accessible and comes with native Google Assistant, Alexa and yes, HomeKit compatibility.

WeMo is not our favorite application and you will not get power monitoring with this smart Wi-Fi connector. These shortcomings aside, the space saving design of the smart mini plug and the compatibility of the HomeKit smart connector and the Siri compatibility make it easy for users in the Apple ecosystem.

The $ 80 iDevices exterior switch is a great way to automate exterior lights, fans, lamps, switches, or other electronics for the terrace. It works with Google Assistant, Alexa and HomeKit over Wi-Fi and includes power tracking and remote control.

While you will get two points of sale, you cannot control them individually. If this is essential for you, we recommend that you check out the iClever Smart Plug, which uses the Smart Life application as a control center to remotely control your devices.

Other models I've tested

There are dozens of smart plugs, from large and small companies, and although I didn't test each one, I saw quite a lot through the CNET smart home. Here's a quick look at other notable options.

• Amazon smart plug: Amazon's smart plug costs $ 25 and only works with Alexa. Although the configuration is easy, it is not as rich in features as other models.
• Satechi Dual Smart Outlet: This smart homeKit smart connector costs $ 30 and you'll get two sockets and power monitoring capability. There is no support for Google Assistant or Amazon Alexa.
• iHome Outdoor: This $ 40 smart outdoor connector works with all three voice assistants, but you'll only get one store.
• ConnectSense Smart Outlet 2: This $ 60 deal does everything - power monitoring, individually controlled outlets, a USB port, and LED status lighting. However, the price and unattractive, oversized design are enough to keep me from recommending it.
• Koogeek: This $ 32 smart connector works well with HomeKit, but blocks adjacent sockets. Google Assistant and Amazon Alexa integrations are not as uniform as we would like.
• Puregear Pureswitch: This smart connector focused on HomeKit is another solid choice for Apple smartphones, but it didn't work as well in our testing.
• Eufy smart mini plug: This smart paint size plug is slightly larger than our SmartThings budget above and costs a few dollars more at $ 23. You'll also get Amazon and Google Assistant smartphones.
• Wyze smart plug: This two-money package for only $ 15 is incredibly cheap and works well. It works with Google Assistant and Amazon Alexa, but there is no power monitoring.

Things to remember

Choosing the best smart connector for you starts with voice assistant compatibility. Choose a plug that works with any voice assistant you use, whether it's a smartphone, tablet or other device. You can usually find this information in the product box, website, or voice assistant mobile app.

Next, consider where the socket will be located and whether it is blocking other adjacent sockets. If so, make sure you choose a plug that is not too big. Most models described as "mini" will save space.

Additional features such as power monitoring and USB charging can add even more control and convenience. Regardless of the smart plug you choose, daily plug-in online products are one of the easiest ways to automate and smart your home.
