Things to Look Out For When Choosing a Smart Light Switch

Few would argue that smart light switches are the foundation on which a fully integrated smart home is built. However, if you start looking for the right switch for your home, you'd soon realize that it can be quite difficult to differentiate between all of the choices that are available. Don't worry. This is where we come in. We will help you figure out the best smart light switch for your home.

Smart Switch – Smart Plug

You probably have to decide between getting a smart switch or a smart plug. Both of them are incredibly convenient and toggling them is just as natural as a standard light switch. If you want to keep your conventional switches but still automate your lights, then you would want to go for a smart light switch. Smart plugs, on the other hand, don't have the same manual switches but include sophisticated power monitoring features that most switches don't offer.

Operating System of Your Choice

The choice of software or operating system is just as important as the hardware. Although most devices will work on both Android and iOS, some switches will work better with one operating system and sync well with your existing devices such as Nest or Ecobee.

Wireless Connectivity

We usually don't give much thought to wireless connectivity, but there is more to it than just Wi-Fi. Wi-Fi, ZigBee, Z-Wave, and Bluetooth are some of the most commonly used medium for wireless communication. Each of these communication protocols has their own advantages and disadvantages, and you want to make sure that you opt for the right protocol for wireless communication in order to ensure seamless connectivity between all of the devices in your home.

Frequently Asked Questions

Why Shouldn’t I Just Stick To My Old Light Switches?

For most of us the idea that, if it isn't broken, don't fix it, works fine in most cases. However, that concept doesn't really apply to upgrading to new technologies. Our old phones worked just fine, yet all of us upgraded to smartphones and continued to do so when newer models are available.

There is a good reason for opting for smart light switches, and it's not just convenience. Smart light switches play a huge role in reducing our electricity bills. It also provides a sense of security and helps in the overall integration of all of our daily use items.

How Does Smart Light Switch Factor in a Smart Home?

The smart light switch is just a small cog in a much greater system. Smart light switches are the building blocks on which a fully integrated and interoperable smart home operates. It provides connectivity with smart lighting, smart cooling and heating, and smart security systems, and offers absolute control over the home via a simple smartphone app.

This interconnectivity allows the local network to generate data over the home occupant’s behavioral patterns and slowly allow the home to become fully automated for most of the daily mundane activities based on pattern recognition.

How to Deal with Multiple WAP Environments?

Most homes will have multiple wireless access points or WAP in order to ensure complete Wifi coverage of the home. This shouldn’t be much of an issue as despite the number of WAP, you can maintain a single local network for your home, which the WAP leads to. So irrespective of the WAP used by a device, it will still connect to the central virtual network that connects all of the devices together.

How Do I Deal with Intermittent or Patchy Wi-Fi Network?

There are a number of things that can deal with this issue. First of all, most routers have a limit on the maximum number of devices that can connect to it. If you exceed this number, it may cause some devices to get dropped from the network. Check your router's specification and either upgrade to a router with a greater limit for connections or opt for a smart hub.

As for the quality of the Wi-Fi connection, you simply have to take into account the location of the devices and make sure they're not obstructed by furniture, especially by metal columns. Metal can create severe interference in Wi-Fi signals.

What to Do in the Case Remote Access Fails

In rare circumstances, you'll notice that remote access to your smart light switch fails. In such cases, you can go into the settings tab in the smartphone app and make sure remote access is enabled. Check if your internet connection is strong enough to handle remote access, weak signals or a slow connection will be unable to handle remote access. Lastly, you can restart your device. It will reset it to its factory settings.

Final Verdict

All of the smart light switches reviewed above were chosen due to being the best smart light switch. So if you are to choose between them, then there are a few factors you can take into consideration.

First of all, do you simply want control of your light switches or are you working towards turning your home into a complete smart home? If you just want to install smart light switches, you can opt for one of the switches that work without a smart hub.

Otherwise, you would need a hub to connect all of the devices. For example, the Z-Wave platform is an excellent choice for a complete smart home, as it supports a wide array of smart home devices that will seamlessly sync together and share data with the central network based around a smart hub to ultimately give you the perfectly integrated and interoperable smart home.
