I’ve bought a led bulb gen6 (RGB) from Aeotec and run to the same problem.
Athom has another focus (i guess ;P) so i clone the repo. Copy the code of the gen5 bulb and changed some id’s.
Now it works for me. Its in this repo:
branch: feature/zwa0002
You can install it with cli.
A pull request should be possible to athom… but the request for the gen6 white bulb is pending for months…
