Frequently Asked Questions

A10: Generally, if it explodes, it is a problem with the customer's installation operation:

a. Not noticed that the neutral line and fire line were brought together.

b. It may be that the neutral line and fire line are connected wrongly.

c. There is also connected to high-power equipment.

Answer :
(Method 1): The signal is not good or there are too many devices. It is recommended to reset the switch product and connect to the network again, and check whether the connected devices exceed the limit or check whether the network signal is weak
(Method 2): Could you see the device in the App after disconnecting? If you can see it, check the signal strength of the switch (click the switch->Edit->Device Information), if you can’t see the device in the App, check and fix the power failure Whether the screw of the switch is too tight, if it is too tight, loosen it properly, cover the glass panel first, and then power on (note that the glass is covered first and then power on).

Answer 5: Press and hold the button for 5 seconds to confirm whether the indicator light is flashing. If the non-flashing, the switch is broken, the flashing is the connection method problem

Answer 7:
(Method 1) The voltage and current are unstable, and the load may be too large. It is recommended to first check whether the power of the electrical appliance exceeds;
(Method 2) Turn off the power and check whether the screw that fixes the switch is too tight, if it is too tight, loosen it properly, cover the glass panel first, and then power on (note that the glass is covered first and then power on).

Answer 8: Yes, two bulbs are connected in parallel

Answer :
(Method 1): It is possible that it has been set the cycle timing function. If this function is not needed, it is recommended to turn off this function in the mobile phone APP

(Method 2): Turn off the power and check whether the screw that fixes the switch is too tight, if it is too tight, loosen it properly, cover the glass panel first, and then power on (note that the glass is covered first and then power on).

Answer 3: The wrong wiring or the external capacitor is not connected properly or the wrong wiring burns the switch. It is recommended that the input and output wiring be correct. The capacitor is installed correctly

Answer 4: The capacitor is installed at L1, not behind the switch but where the lamp is.

Answer : 
(Method 1) The wrong wiring or the external capacitor is not connected properly or the wrong wiring burns the switch. It is recommended that the input and output wiring be correct. The capacitor is installed correctly
(Method 2) If it is the thyristor version, it is that the general thyristor breakdown (overload), if it is a relay, is there any sound of relay pull-in?

A9: solution:

1. If there is no neutral wire, first confirm whether the capacitor has been installed at the light bulb, not at the back of the switch. The capacitor must be installed
2. L1 is the power supply circuit, because the power of the bulb is too small, the current cannot form a loop. It is recommended to install this bulb in L2 or L3, or L4, and then try
3. Since the price of light bulbs is getting cheaper and cheaper now, some factories use cheap materials in order to save costs, and the quality of light bulbs is very poor. According to the quality of the light bulbs, generally the light bulbs below 3W-5W are prone to problems, we recommend replacing the light bulbs, which is safer"
