This device was discontinued a few years ago. As far as I can tell, although it is using zigbee, it was never certified to either ZHA or ZLL profile – – it was considered “manufacturer proprietary.”
At one point, the hue bridge would accept them, but since both devices were made by the same company, that doesn’t tell us anything about how they would work with other zigbee coordinators. And I don’t know if they were visible to the smartthings hub even if they were connected to the bridge.
I do know there were some community members who said they were never able to gain control of the device from SmartThings.
So my guess is they are not compatible, but maybe if someone has them working they will post.
