You May have been confused by the many forum discussions about the use of switches with smart bulbs, like the Phillips hue bulbs.
Any smart switch, whether it’s Z wave, Zigbee, or Wi-Fi, works by maintaining a small amount of current to the radio inside the switch, specifically so that it can hear the next “on” command from the network. When it is turned off, it cuts the downstream current that is going to the light fixture. But the switch radio itself remains powered.
If the fixture contains a smart bulb, like a Phillips hue, then turning the switch off means that the switch can still hear the next network command, but the smart bulb cannot. This can create some complications if you have automations which talk to the bulb directly rather than just using the on/off through the switch.
However, as long as you are using dumb bulbs with the smart switch, there’s no problem at all. When the switch is turned on, either manually at the wall or via radio, current goes to the fixture and the bulb comes on. When the switch is turned off, again either manually or via radio, current is cut to the fixture so the bulb goes off, but the radio inside the switch remains powered so it will still hear the next “on” network command.
So as long as you were planning to use dumb bulbs, there should be no issue.
If you were intending to control the current load to smart bulbs with smart switches, it gets a little more complicated, but that is true of any brand of smart switch, not just GE.
Most people use dumb bulbs with smart switches. The exception would be someone who wants a feature only available with a smart bulb, typically the ability to change colors.
