Function Introduction

  • The color value of Tuya Color Light DP adopts HSV color model, and the string value corresponding to the HSV model color is sent through the panel.
    1. Hue (H) Hue adjustment range: 0-360, the range of the value sent by the panel is 0-360, and the color ring adjustment range and the value sent by the panel are in a linear correspondence.
    1. Saturation (S) Saturation adjustment range: 0%-100%, the range of the value sent by the panel is 0-1000, and the color ring adjustment range and the value sent by the panel are in a linear correspondence.
    1. Brightness (V) Brightness adjustment range: 1%-100%, the value range sent by the panel is 10-1000, and the color ring adjustment range and the value sent by the panel are linearly corresponding.
  • Color light supports display:
  • Three channels
  • Four channels
  • Five channels

How to develop

Notes

  • Protocol issues:
    • Sig Mesh
      • dpCode "control_data" is not supported for real-time sending
      • It is not recommended to have a smearing interaction mode. If the operation is fast, it is easy to lose packets. You can consider the click interaction mode.
      • If the interaction is changed after smearing, it is also possible to send it down.
      • The principle is: a large amount of DP data cannot be sent down in a short period of time.
    • Beacon
      • Since Beacon DP data is only sent down and not reported, the relevant data needs to be stored in the cloud to ensure the synchronization of the status.
