Correct, it is unlikely that the hue bridge will expose it to HomeKit for the reasons we’ve discussed elsewhere.
RGBGenie has put considerable effort into their devices, including getting some safety certifications (although not UL in the US). They seem to be aiming for a combination of the Phillips hue bridge and the Amazon echo plus market, which is a good thing. There are some community members using some of their products, Although I don’t recall discussion of that particular model.
There were some timing issues initially, and it will probably work best with the newer hub models for now. I think @vseven knows the most about them right now.
