This topic describes how to create a lighting product with a no-code solution on the Tuya IoT Platform, using Wi-Fi multicolor light (RGBCW) as an example.

Background information

The no-code solutions for LED lighting products on the Tuya IoT Platform cover four types of communication methods, each of which includes five control modes.

  • Dimmable white light (C)
  • Cool-to-warm white light (CW). Cool-to-warm white light (CCT)
  • Multicolor light (RGB)
  • Multicolor light (RGBC)
  • Multicolor light (RGBCW). Multicolor light (RGBCCT)

    Create Smart Light

    Note: If the functionality provided by the no-code solution cannot meet your requirements, you can turn to custom solutions with the reference of SoC Custom Firmware.

  5. Complete product information.

    • Product Name (required): Enter brand and product name. The name is displayed on the app’s control panel.
    • Product Model (optional): Enter the product’s model number. Multiple model numbers are available, separated by a half-width comma.

      Note: The model number will not be displayed on the app. It is recommended to enter the internal model name or customer’s product model to ease product maintenance and order management on the IoT Platform.

  6. Click Create. When a product is created, the page automatically jumps to Create Standard Functions of the step of Function Definition.

Define product functions

Procedure

  1. Select the desired functions from Create Standard Functions window and click Confirm.
    Create Standard Functions

    Note: The required functions cannot be removed from the selected functions.

  2. On Function Definition page, enable Cloud Functions as needed. (Optional)
    Create Smart Light

  3. Click Next: Device Panel at the bottom of the page. The page jumps to Device Panel.

Configure device panel

This section describes how to configure an app panel, using a visualized panel and its default configuration as an example. If you require custom panels or panel editing, you proceed with relevant operations as per the prompts.

Procedure

  1. On the Device Panel page, find an ideal panel and click Apply.
    Create Smart Light

  2. You can change or edit the panel as needed. Scan QR code with Tuya Smart app to preview. (Optional)

  3. Click Next: Hardware Commission. The page jumps to Hardware Commission.

Hardware commission

You can define the electrical parameters of the module. It is recommended that an engineer define the professional parameters.

Background information

Currently, Tuya provides ten types of Wi-Fi modules. You choose an ideal one based on specific product features such as packaging requirements, mounting space, temperature conditions, and antenna specifications.

Product category Recommendation
Bulb TYE3L module
Filament lamp TYLC5 module
LED candle and GU10 TYLC4 module
Lights using internal LED driver or metal housing LED driver TYE1S-IPEX module supporting external antenna
Lights using plastic housing LED driver TYE1S module with onboard antenna or TYE3S module
Compact products, such as strip light controller TYE2S module

Note:

  • Provide module instructions and I/O schematic diagram for your reference.
  • The EN pin of the E3S and E3L modules shall be tied high.
  • Give the best attention to RF reference design.

Procedure

  1. Select a module as required.
    Create Smart Light
  2. Configure firmware parameters in the Generate firmware 1 To be generated. The specific parameter configuration is as follows.
    Create Smart Light
Parameter type Parameter Description
IIC configuration Ctrl configure When the light is turned on, high level is output, while when the light is turned off on the app, low level is output to shut off white and RGB circuits for reducing standby power.
Note: If Product drive mode is set to IIC-SM726EB, only the RGB circuit can be shut off.
IIC clock signal—IICSCL Select a pin from the pull-down menu and the selected one cannot be used for other parameter configuration.
IIC control data signal—IICSDA Select a pin from the pull-down menu and the selected one cannot be used for other parameter configuration.
Networking set Number of ON/OFF to reset The number of on/off operations that trigger reset network pairing. For example, if the parameter is set to 3, the network pairing will be reset after the "on, off, on, off, and on" operation is performed.
Color Red drive pin-R Select a pin from the pull-down menu and the selected one cannot be used for other parameter configuration.
Green drive pin-G Select a pin from the pull-down menu and the selected one cannot be used for other parameter configuration.
Blue drive pin-B Select a pin from the pull-down menu and the selected one cannot be used for other parameter configuration.
White drive pin-C/Bright Select a pin from the pull-down menu and the selected one cannot be used for other parameter configuration.
Warm drive pin-W/CCT Select a pin from the pull-down menu and the selected one cannot be used for other parameter configuration.
Product functional relevance White mode maximum brightness The highest duty cycle output from the white light I/O or the dedicated IC output.
Value range: 1–100.
White mode minimum brightness The lowest duty cycle output from the white light I/O or the dedicated IC output.
Value range: 1–100.
Note: Select the applicable minimum brightness according to the hardware IC. Improper settings may cause the lights to flicker.
Frequency of PWM The too high or too low frequency will cause jitter and stroboscopic effect.
Value range: 100–20000. Default value of 1000 is recommended.
Color temperature adjustment drive
  • CW: One PWM controls cool light and the other controls warm light.
  • CCT: One PWM controls brightness and the other controls temperature.
Product drive mode The mode to drive LED lamp beads.
  • PWM-RGB: SoC module's I/O outputs adjustable duty cycle drive, including white PWM and RGB PWM.
  • IIC-SM726EB: Dedicated driving chip for the LED lighting system, including white PWM and RGB IIC.
Power memory mode After the product is powered off and restarted, whether to recover to the last set state, such as color, brightness, color temperature, and scenario mode.
Note: Power-off memory takes effect after the current state lasts for five seconds.
Switch gradual How brightness changes when the light is on/off.
  • On/off without gradual change: Brightness does not change when the light is on/off.
  • On/off with gradual change: When the light is turned on, the brightness will gradually change from 0% to 100%, while the brightness will gradually change from 100% to 0% when turned off. The longest gradient duration is 800 milliseconds.
Product distribution network options Pairing reminder brightness The indicator brightness during network pairing.
Value range: 10–100.
Normal brightness The initial brightness of the always-on indicator after the network pairing is successful or when the pairing mode indicator is always-on.
Value range: 1–100.
Normal temperature The initial temperature after the network pairing is successful or when the network pairing indicator is in always-on mode after power-on.
Value range: 0–100.
