Script for fixing colortemp issue with IKEA Trådfri lights on Philips Hue Bridge

Trådfri Hue Workaround

Workaround Script for fixing brightness and colortemp issue with IKEA Trådfri lights on Philips Hue Bridge. It works by continuously polling the Hue Bridge to detect change in both properties, then resend update commands to the Trådfri light after a short period.

Requirements

You'll need a PC or server where the script can run in the background. Install python requirements with

poetry install

Usage

Simply start the script with Hue Bridge IP and Trådfri light ID's as argument. Press the bridge button before running it the first time.

poetry run python tradfri_hue_workaround.py <bridge_ip> <light_id_1> <light_id_2> ...    

You can also list available lights and ID's:

poetry run python tradfri_hue_workaround.py <bridge_ip> -l

Background

There's a compatibility issue with IKEA Trådfri lights and Philips Hue Bridge where the brightness and colortemp are not set correctly when changing scenes. The Hue Bridge will first send a command for change of either of the properties, then the other. The Trådfri light will not accept any commands while it is busy changing the first property and discards the command to change the other one. This results in a missmatch where the Hue Bridge thinks both properties has changed, while it has actually not changed.
