FAQ
-
Problem 1: The Wi-Fi switch is often disconnected in APP
Answer 1: (Method 1): The signal is not good or there are too many devices. It is recommended to reset the switch and connect to the network again, and check whether the connected device exceeds the limit or check whether the network signal is weak
(Method 2): Can you see the device in the App after disconnection, if you can see it, check the switch signal strength (click Switch-> Edit -> Device Information), if you can’t see the device in the App, power off to check Whether the screw that fix the switch is too tight, loosen it properly, cover the glass panel first, and then power on (cover the glass before powering on). -
Question 2: WIFI switch automatically turns on and off the lights
Answer 2: (Method 1): It is possible to set the cycle timing function. If this function is not needed, it is recommended to turn off this function in APP (Method 2): Turn off the power and check whether the screws that fix the switch are too tight. If they are too tight, loosen them properly. First cover the glass panel and then power on (the glass should be covered before power on). -
Question 3: The WIFI switch cannot be turned off and on
Answer 3:lt caused by wrong wire or the external capacitor is not connected well. Wrongly wired switch may burn out.It is recommended that the input and output wiring are correct. The capacitor is installed correctly -
Question 4: How to install the capacitor
Answer 4: The capacitor connects Ll and Non the light not behind the switch. -
Question 5: The WIFI switch cannot be connected to the Internet, and the signal cannot be found
Answer 5: Long press the button for 5 seconds until the indicator light flashes. If the non-flashing switch is broken, indicator light flashing is the problem of the connection method -
Question 6: The switch can be turned on and off, but the light cannot be controlled Answer 6: (Method l)lt caused by wrong wire or the external capacitor is not connected well. The wrongly wired switch may burn out.It is recommended that the input and output wiring are correct. The capacitor is installed .correctly
(Method 2) If it is a thyristor version, the thyristor will generally break down (overload), if it is a relay, whether there is a sound of the relay picking up -
Question 7: It can be used normally at the beginning, but it cannot be used normally after one month. Is it because of what caused the burn? Is it because of overloading?
Answer 7: {Method 1) The voltage and current are unstable,and the load may be too large. It is recommended to check whether the power of the electrical appliance exceeds (Method 2) Turn off the power, check whether the screws that fix the switch are too tight, and if they are too tight, loosen them properly, first cover the glass panel, and then power on ( cover the glass first and then power on). -
Question 8: For example, once it is turned on, can I link 2 bulbs and control bulbs at the same time?
Answer 8: Yes, two bulbs are connected in parallel.
Basic knowledge
- Do not connect the input and output reversely, install correctly
- If there is a neutral line, the neutral line must be installed. There is no neutral line, a capacitor must be installed
- The power is too small, generally do not use it below SW. The power is too large and can not use. Specific view product parameters
- Make sure that the switch is suitable for the local voltage.
Warm reminder
- Do not cover the glass pannel when power is on. The switch will not work when covering the glass pannel with power on. Please restart the main power switch at home.It will work.
- Solve the problem of insensitive touch
Problem: The switch base is screwed too tightly, a gap between the backlight
board and the panel.
Solution: Don’t screw the locking screw too deep, if you can’t reach it, you
can use a longer screw instead; or fill something between the switch and the
bottom box. You pay a little attention during the installation process, the
situation that the touch is too sensitive usually rarely happens
