Its not connected to the other neutral wires that fit in the multiple light switch housing. When someone decides to use the wall switch to shut the light off the power to the bulb is cut which means it will stop being a smart bulb until you turn the switch back on.

Connecting Brilliant When It Is The Only Switch Controlling
Wiring a light switch with neutral. The switch still breaks the circuit but in this case the smart switch can tap into the neutral wire to keep power flowing through the switch the electronics in the switch still break the circuit to the light but the switch maintains a circuit so it is always receiving power. I paint a little and then work on electrical. The light i want to use it on is a single onoff switch not a 3 way switch. The black hot wires are what get connected to the light switch. If you put the loop over the screw in the counterclockwise direction tightening the screw will force the loop open and could create a loose connection. For those of us using led fluorescent or some other energy efficient bulbs under 20w a neutral is required.
Buy a smart switch that works without a neutral. Call in an electrician and get him to run a neutral wire running from the light fixture to the switch. You could also ask the electrician to rewire both the switch and light fixture but this is more complex and therefore costlier. Again excuse my paint covered hands. Yes there are a fewread very very very few switches that dont require a neutral but those will limit you to incandescent only. When i remove the face plate the neutral wire is wired to the light switch on its own.
So when the switch is off all hot parts of the lamp are well protected. And when the switch is on only the tab at the bottom of the socket is hot but if the wiring is reversed and the power goes to the threaded socket the threaded socket is always hot whether the switch is on or off. Of courseand look for a neutral white. The white neutral wire from the power source and the white neutral wire that goes to the light fixture get connected to each other. Im having trouble installing a wemo wall switch. The hot and neutral terminals on each fixture are spliced with a pigtail to the circuit wires which then continue on to the next light.
Wrapping the wire clockwise when wiring a light switch ensures that the loop on the end of the wire will tend to close when the screw is tightened. Wiring a light switch is very simple. The threaded socket is the neutral. There are a couple smart switches that work without a neutral. The most common requirement of any hardwired automated light switch is a neutral wire. This diagram illustrates wiring for one switch to control 2 or more lights.
1 run a neutral wire. Multiple light wiring diagram. Here is a diagram of a standard switch with a neutral wire. The source is at sw1 and 2 wire cable runs from there to the fixtures.
