5 Best Smart Relay Switches to Make Your Existing Sockets Smart

A smart home is a dream for most tech enthusiasts. However, it’s hard to make all sockets and outlets smart, unless you build a new house and do the appropriate rewiring. Of course, you can use smart bulbs and plugs to achieve the desired goal, but the apparatus will not be as seamless. There is another workaround, though, to connect existing sockets to your network – that being via smart relay switches.

Relay switches are tiny circuits that can be connected to your existing switchboards. These smart Wi-Fi relay switches then interface with the internet and control the socket they’re connected to. Whether it’s a wall outlet, a light bulb, or your air conditioner, use any of the smart relays mentioned below to convert your house into a full-fledged smart home. But before that –

Difference Between Smart Relay Switches and Conventional Smart Sockets

A smart socket replaces your entire wall outlet. It requires more labor and costs more as well. A relay switch — on the other hand — is a tiny addition that needs to be wired to your existing wall outlet. It’s a cheaper and more efficient solution.

1. Colorock Remote Switch

Current: 10A

The Colorock smart relay switch is the most affordable option on the list. Despite that, the switch has a good array of features too. In fact, it’s the only switch on the list that can be operated via an included RF remote.

It’s quite smart of Colorock to include an RF remote with the switch since you won’t have to use your phone every time to control the switch. Of course, you can also connect the switch to your Wi-Fi network and control it via the app. With support for Alexa and Google Assistant, you can even use your voice to turn a device on or off.

Colorock’s app also allows you to set scenes and schedules. If you want to turn on your AC at 11 PM and turn it off automatically at 1 AM, you can simply program it in the app. As per reviews, the RF remote works flawlessly, but the Wi-Fi connection can be intermittent. So, pick Colorock’s option if you are going to predominately use the bundled remote.

What We Don’t Like

  • Intermittent Wi-Fi connection

While the Colorock relay could only handle 10A of current, Rodot’s offering is rated for up to 16A. As a result, you can use the Rodot Wi-Fi smart home relay to power large appliances like water heaters and air conditioners.

While the Rodot smart switch misses out on the RF remote, it offers support for Samsung SmartThings. As such, if you have a bunch of IoT devices working with Samsung’s smart home ecosystem, the Rodot relay will fit right in.

The relay is also smaller in terms of the overall footprint compared to the Colorock smart switch. So, if you have a small switchboard or a single switch, you can opt for Rodot’s relay as well. And lest we forget, you get two switches in the box, which is excellent.

Unlike any other smart relay mentioned above, the Yitouniu Wi-Fi smart switch has a built-in temperature and humidity sensor, which opens up a ton of opportunities for automating your home.

With the help of the onboard temperature sensor, you can automate when to turn your AC on or off. For example, you can set your AC to turn on automatically when the temperature crosses 85 degrees. And once the temperature comes down to around 65 degrees, the AC will automatically shut off to save power.

Now that’s extremely useful and would generally require a smart plug along with a sophisticated smart home hub with a built-in temperature sensor like the Amazon Echo Dot 5th Gen.
