Control4 uses their own proprietary coding. Not compatible with SmartThings.
The Zigbee standard allows for the use of multiple profiles, including manufacturer-proprietary, which are not all compatible with each other. They don’t even use the same addressing schemes.
SmartThings uses the Zigbee Home Automation profile 1.2 (ZHA 1.2). So when considering a new device, the first thing to check is if it is certified for ZHA 1.2. Which the linked device, like almost all Control4 devices, is not.
There are more details in the community-created wiki:
Thanks JD. I had seen some evidence of success with Control4 & ST integration elsewhere, where it appears at least one of the Control4 devices he’s using speaks a version of HA.
But Patrick hasn’t updated that thread in a while. I just bid on one of the extenders on eBay for $49… not sure if it has a reserve, so if I don’t win it then /shrug and if I do then I may dust off some of my skills & poke around with it a bit.
@pstuart is a grandmaster at integrations, but I think he’s only been working with Control4 sensors, a much simpler task than a device like the extender. But he would certainly know more about what might be hack able.
As far as out of the box integrations, though, ZHA 1.2.
He has been able to make some ST devices controllable by Control4, but that still requires a Control4 license.
