Since version 2.1 of Matterbridge the dimmers should show up as 0x0101. Unfortunately I don't have the twist but for example my tuya dimmer is now shown correctly.

With the new Matter update, I'm in fact using a flic button as a doorbell button, together with Home assistant. It's working great with the Matterbridge addon, and a Boolean helper that's visible in the Flic app.

@Emil Yes, that seems to be the fact in my Matterbridge too. However my HA automations for increase or decrease the dimmer is populated as 010A, and it's accessable from the Flic app, so I can with my ordinary flic buttons for instance click or doubleclick them to dim up and down them perfectly. Just tried it. It's not perfect but a workaround until fixed. Guess it should work in the twist as well, at least if every smaller twisting is sending a command, like a click.

@mon-bosma Sorry I don't have the twist, so can't try that. But it's strange if there's something different with the twist then.l mean every function in it should theoretically show up in the app. Maybe I should buy one just for fun.
For my Ikea Remote, I managed to, kind of use the dimming function for a tuya dimmer by, in tuya make a 10 % up or down action and in HA tie this to that action, maybe it's possible to do something similar until they find a resolution? Sorry, I'm just a beginner in all this.

Hi, it's working great with the addon Matterbridge. See my post

Hi, I can confirm that the addon Matterbridge works beautifully with the Flic Matter beta.
I just scanned the addon with the flic app and all home assistant entities are now exposed in the app. Even the automations. Then it's just to add flic button actions like always. Worked great, first try.
