This happens because LED technology requires very little power to operate, and when replacing a non-LED product with an LED one, residual voltage in the circuit may cause flickering or faint illumination.

How to fix it?

Simple: install a capacitor in the circuit. This device stores the residual voltage and eliminates the flickering problem.

1. Download the Tuya Smart app from Google Play or the iOS App Store.
2. Open the app and register a new account (or log in if you already have one).
3. Turn on your Tuya Smart devices and pair them with the app.
4. (Optional) Rename your devices in Tuya Smart (e.g. name your ceiling light “Living Room Fan”) — Alexa will detect this name.
5. Download the Amazon Alexa app and connect your Echo device.
6. In the Alexa Skills Store, search for “Tuya Smart”.
7. Enable the Tuya Smart skill and log in with your Tuya account credentials and region.
8. Say: “Alexa, discover my devices.” Wait for Alexa to confirm device detection.
9. Setup is complete. Try controlling your devices with voice commands.

Sample Alexa voice commands for Tuya Smart:

• Alexa, turn on Living Room Fan 
• Alexa, turn off Living Room Fan
• Alexa, dim the living room light
• Alexa, brighten the living room light
• Alexa, set the living room light to 20 percent
• Alexa, set the bedroom light to green
• Alexa, set the bedroom light to cool white

This is the method to pair the ceiling light with the Tuya system so that voice recognition with Alexa or Google Home works.

To put these ceiling lights into pairing mode, you must do a sequence of power offs and ons — it’s 3 ons and 2 offs.
If done within the times we indicate, the ceiling light will begin blinking.

ON ——< 5 sec———- OFF ——–∞ ——– ON ——–< 5 sec——– OFF ———-∞ —— ON ————- (BLINKING)

Why does the ceiling light blink sometimes without having done the sequence?

This happens because sometimes when we turn on the ceiling light and turn it off in less than 5 seconds — for example, if we enter a room by mistake or regret turning the light on — if this happens twice, even if not close in time, the next time we turn the ceiling light on, it will blink.

The ceiling light needs two ON-OFFs of less than 5 seconds and another ON.
But they don’t have to be consecutive, because between the OFF and the next ON there is no minimum time, it’s infinite time — it can be hours, a day, or any amount of time.

The ceiling light has a counter and it will blink after two ON-OFF sequences of less than 5 seconds.

The counter will reset to zero if you do an ON-OFF of more than 5 seconds, and the sequence will need to start again.

For this reason, it’s not usual for an unintentional blinking to happen, but it can happen.
It’s not a failure, it just means that the sequence was accidentally performed.

Is there a solution?

The solutions are:

• Try to use the remote control, the app, or voice commands to turn the light on and off.
• If you usually use the wall switch, try not to turn it on and off in less than 5 seconds, because if you do it twice, pairing mode will start.

As we said, it’s quite rare to do it by chance, but it can happen.

If blinking starts, turn off the power from the switch, and the blinking will stop.
