- Use a IKEA Tradfri on/off remote to turn on/off or dim a light
- Light dimming should be smoother compared to other blueprints
- Works with ZHA
So I tried the one from Awesome HA Blueprints but thought the dimming experience wasn’t that smooth. Then I tried ControllerX which did make things way more smooth, however I really like having all my config in one place and rely less on external tools.
So as a fun proof-of-concept I created this blueprint that uses the transition feature instead of multiple calls to increase/decrease the brightness. In short:
- When you start holding the button down a transition towards full/zero brightness starts
- When you release the button it cancels the transition by sending a guesstimate of what the current brightness should be, based on how long you held the button down and how fast you want the dimming to be
To my surprise it works fairly well and so far my dimming experience has been smooth
Enough talking, you can get the blueprint from GitHub Gists or down below:
