Luckily, there is an affordable line of products you can install with the same basic electrical skills needed to install a smart switch. These products are wireless relays for home automation.
What is a wireless relay or smart relay?
A relay, in a general sense, is a device that has an input circuit and an output circuit. When the input circuit is closed, the relay closes the output circuit. In many cases, a relay allows a low-voltage or low-amperage signal circuit to activate a higher-voltage or higher-amperage output circuit.
In this context, a wireless relay or smart relay is a device that wires in with your existing light switch. The wireless relay then connects to your Wi-Fi network (or other home automation network depending on the relay you purchase). Just like other smart home products, once the relay is on your network, you can then control it through its proprietary app or through other hubs or assistants, such as Google Home or Amazon Alexa products.
