1. Power off the break
2. Find Neutral Wires.
Make sure there is a neutral wire for the Wi-Fi switch. If not, the switches cannot work properly. Neutral
wires are white and NOT used by your old switch. You can send us photos of the wiring status.

Notice:
1. Three lines must be connected (Live Line, Load Line and Neutral Line);
2. If you really cannot find out a Neutral Line in the outlet box, STOP installing the switch and consult with
a professional electrician or contact our service team.
3. After correct wiring, the switch must work well manually. Then, go to pair the switch on App.

4. FQA:
1. How can I know it is connected correctly?
A: Press/Tap the switch button. It will work well manually after correct wiring.
2. I cannot find the neutral wire in both outlet boxes; Can I still use this switch?
A: No, the neutral wire is necessary for the Smart Switch.
Although old switches do not need a neutral wire, there are spare white neutral wires in common outlet
boxes. Please send us photos of the wires inside the outlet boxes for assistance.
3. How can I find which one is the live (hot) line, which one is load line?
A: Besides the ground wire, there are two wires on your old switch in general:
Use a tester to check which one has power when the old switch is off status;
You can connect them on wifi switch by trial and error;
