I have pretty much given up hope for this, considering they refuse to say anything, or give any updates since it's release.
I was reading about the Philips Hue Tap Dial. I thought since it was Hue, it was going to also be useless, like the twist, but upon further investigation, turns out it is a Zigbee Dial (with 4 buttons), that works with Home Assistant and Zigbee2Mqtt out of the box (as any smart home device worth anything should). I just ordered a few of them and will be here Saturday.
If it works, I will probably just toss all this flic equipment I was conned into buying.
--- Update: The Hue Tap Dial works great, so I bought 3 more. Was able to get it up and running with Zigbee2Mqtt straight away. Used NodeRed to translate the rotation +speed to dim %, and made 1 of the buttons be a simple light toggle. There are 3 other buttons that can be used, which report press, release, hold, hold release.
The rotation reports whether it was a step, slow turn, or fast turn.
Best of all, it works exactly as advertised, and I was able to use my existing hardware (doesn't require a proprietary hub, not even the hue hub. Connected straight to my Zigbee Coordinator). Sure, it doesn't have a fancy incremental light on it, but a lot of good that was doing me with the Twist...
