![]() When planning on upgrading your home with smart lighting, it’s always better to purchase products from a trusted manufacturer with a comprehensive warranty-especially when dealing with electrical products that attach to your home’s wiring. Occasionally, the low prices on these units reflect sub-par manufacturing. If you’ve purchased inexpensive light switches from some discount retailers, the switches may have malfunctioned internally. ![]() Before you change your Wi-Fi password, consider the number of devices you’ll have to reconnect when you make the change. Resetting old passwords is an essential part of having a secure network, but Wi-Fi password changes can wreak havoc on smart home products. If you have a large home, consider using multiple routers to avoid lapses in coverage. Consider moving your router to a more central location, allowing it to service all of your smart devices. In the same vein, if you’ve moved your router, the switch might now be out of range. In this case, you either have to switch off 5GHz or replace older 2.4GHz switches. Many newer routers use a 5GHz signal by default, which means some older 2.4GHz switches will not connect after a router upgrade. Oftentimes, a smart switch will stop working due to incompatible Wi-Fi. Fortunately, the disconnect only occurs for one of a handful of reasons. ![]() To get the switch working properly, you'll first need to troubleshoot and identify the cause of the disconnection. You may also notice the LED on the switch turns red or blinks. When this connection is interrupted, the switch can stop responding to voice or app commands. ![]() "By enabling the wireless control of each section of homes, our solution prevents unnecessary use of energy, which in turn lowers energy bills and reduces carbon emissions," says Moez.Smart switches are among the best products to increase your home's IQ, but they depend on a wireless internet connection to function correctly. The "seamlessly automated" system could also turn lights on and off as occupants move from room to room. If your house has wirelessly controlled vents, you can close the vents outside that room, or maybe a couple of bedrooms," says Moez. "Imagine heating a 3,000-square-foot house, but you're only using a room at any given time. The switch can also accommodate sensors for temperature, humidity and occupancy that can drastically reduce energy consumption. With the current housing crisis in Canada, Moez says his innovation could help reduce construction costs. In 2018, Alberta became the first province to allow wireless electricity control in new homes. The system is "scalable, easy to replicate and adopt, and can be customized to meet the specific needs of homeowners, contractors and regulators," he says. Moez has so far developed a prototype switch for less than one dollar that can be installed anywhere on a wall. Instead, each floor would have one or two RF ( radio frequency) power transmitters to power up all switches inside the house. What makes his system unique is that the switches run without batteries, harvesting energy from ambient sources such as radio frequency signals. "If you have 50 wireless light switches in a house, it's very inconvenient for an average homeowner to run around and replace batteries all the time," he says. Wireless switches-consisting of a transmitter on the switch and a receiver near a light fixture or other appliance-have been around for many years, and have been proven that they can reduce the material and labor cost for wiring houses, says Kambiz Moez, director of electrical engineering in the Department of Electrical and Computer Engineering, but they require batteries to operate.
