- Give a description of the problem
Update the white color temperature (2700K-6500K) of a tunable LED bulb based on reading from a color sensor.
I built a piston that updates the white color temperature of a tunable white LED bulb based on the current ambient light levels outside as measured by a NodeMCU ESP8266 device hooked up to an Adafruit color sensor.
1 What is the expected behavior?
New color temperature reading, bulb ‘fades’ to the new reading smoothly (or at least as smooth as possible since there is no device level fading on this)
2 What is happening/not happening?
It works if I use the ‘Set Color Temperature’ task to update the bulb but it’s very abrupt as there is no fade. I tried the task called “Fade Color Temperature…” which is supposed to be emulated (not device level ) but it doesn’t work at all unfortunately, the color temperature never changes.
Since this looks like it might just be a bug, I was trying to just build my own ‘fade’ script with a while loop or a for loop incrementing a variable until it reaches the desired color temperature value. I couldn’t quite figure it out though. Can anyone help me out with this?
