Successfully Setting Up Color Temperature with Tuya RGB Lights via MQTT

General

Hey everyone, I wanted to share my experience with setting up color temperature on my Tuya RGB lights using MQTT. I’ve been tinkering with home automation for a while now, and this was a fun challenge that I finally cracked! :tada:

Initially, I was having trouble getting the color_temp value to work as expected. I was sending the payload through MQTT, but the lights weren’t responding the way I hoped. After some research and trial and error, I figured out that the key was adjusting the value_template to ensure it was within the acceptable range for the Tuya device. Specifically, I had to scale the input value correctly to match what the bulb expects.

Here’s a quick rundown of what worked for me:

  1. MQTT Trigger Setup: I used a trigger that listens to the house/rgb_balcony_projector_color topic. The value_template calculates the color temperature based on the incoming payload. I found that multiplying the payload by 347 and adding 153 gave me the right scaling for the bulb.

  2. Automation: I set up an automation that turns on the light with the calculated RGB color. It’s super smooth now, and the bulb transitions beautifully through different temperatures.

  3. Testing and Tweaking: I spent some time testing different values to make sure the color temperature transitions were smooth and accurate. It’s all about finding the right formula that works for your specific device!

If anyone else is struggling with similar issues, I’d recommend checking your value_template calculations and ensuring that your payload is within the expected range for your device. It’s all about that perfect balance of scaling and offsets! :rocket:

Happy automating everyone! Let me know if you have any questions or tips to share. :blush:
