The time it takes to install smart home technology depends entirely on what you’re installing and how many devices you’re working with. Generally, though, it shouldn’t take more than a few hours to install a couple of new gadgets, except in certain complicated situations. A set of smart lightbulbs should take only a few minutes to set up. Other smart home technologies, like smart thermostats, could take more time. Smart thermostats require disconnecting and reconnecting some wires. You can always spread out the setup and installation of your smart home device across a weekend.
