Early hands on reviews look good on this, and I have to say I really like their UI design as far as exposing parameter settings.
I don’t know if it would be possible to add a smartthings hub as a secondary to this or not, if you could, that would be very cool.
HomekitNews did their usual very detailed review.
Note that not everything is exposed to HomeKit. Some device classes don’t carry over and some individual features are also missing. For example, HomeKit does not yet have a device class for UV sensors, so one of the Fibaro multisensors only exposes some of its capabilities in the Home app. Also, double tap appears to be missing on most buttons, but you do get press and long press.
Anyway, this could also be a good indication of how matter bridges might come into the Home app.
Here’s the previous discussion thread from this forum about this device with a few more details.
