@amir I just received the Flic Twist from the Dec 2021 Kickstarter campaign, and from what I see here in this thread is that now almost two years later what I received is not usable for anything I'd need it for. I have the whole house set up with Lutron Caseta dimmers with Lutron HomeKit bridge, some Nanoleafs that are HomeKit native, and an IKEA Trådfri gateway controlling couple of kitchen lights. My music is played on a dozen HomePod stereo pairs in different rooms. I can't control any of the lights directly or access any of the HomeKit lighting Scenes, with the possible exception of directly controlling the two IKEA lights, which is not practically useful in this scenario. Future Matter support, whenever that may or may not ship, is unlikely to help here as Lutron hasn't AFAIK announced any path for the Caseta system to interact with Matter.
@amir please let me know if I misunderstood something?
