Mini Day & Dusk no longer responding to color temp changes

I currently write a piece of software for the Mini Day & Dusk bulb. Of course, most color commands would not work, but you could set color=kelvin:[1500-4000] using the HTTP API.

Suddenly, a few days ago, my bulb stopped responding to color changes. This used to work:

curl -X PUT "https://api.lifx.com/v1/lights/all/state" \
 -H "Authorization: Bearer MY_TOKEN" \
 -d "color=kelvin:4000"

But it doesn’t anymore. The request responds with an “ok” status like normal, yet the bulb is no longer changing color.

I did upgrade the firmware of the bulb to v3.40, would this have anything to do with it?

Does the Day & Dusk bulb just ignore ALL color changes now? Because before, it would at least react to changing the color temperature.

Any help would be greatly appreciated. Thank you!

We’ve just pushed out a bug fix to the API that should address this issue.
