Set Lamp Color Based on Temperature

[Nezmo]

Hey folks, has anyone got anything already prepared that will set colors on a lamp according the outside temperature? I really thought this would have been done already but a search here and over at ST didn’t reveal anything.

I am playing with my first LED strip (controlled via a Fibaro and custom DTH). One of the things I’d like to do is have the colors set based on the temp from Smart Weather. I can have a go at this but I’m feeling lazy and wondered if anyone has something similar already.

Thanks

Scroll down a few posts until you see someone use “rainbowvalue”. That’s what you’re after.

Change RGB bulb color based on local outside temperature

I posted this on the old forum, but thought I’d repost it here. This uses an RGB bulb to change color based on the temperature outside. It uses SmartWeather device as the temperature sensor. Colors advance through the spectrum from 0F-100F, getting bluer for cold, redder for hot, and all in between. If it’s below 0 or above 100, the bulb flashes three times.

I didn’t like the results from Rainbow value, so I wrote my own expression to do it… So I now use basically the Reverse HSV Gradient shown here:

#153591 to #bc2323 gradient color

I’m going to try things out and see what I like. At least I have a basis to work from now.

Thanks.

Would you mind sharing? I’m wondering about using IFTTT for my WeatherFlow Weather Station to guide bulb color. Thanks
