There is a zwave-IR bridge from Remotec that’s used for air conditioner control ( for ACs that have IR remotes), but it’s limited to the thermostat device class.
A number of community members use global cache’s WiFi-IR device as A code level bridge, but you need to have some piece of software to run it. The HAM bridge is a good choice if you don’t want ongoing fees. Roomie remote (now called simple control) also works, but has continuing fees. Both have smart things interfaces available.
So there are some options to harmony depending on exactly what you want to do.
The following thread was started in the AV context, but does discuss the global cache in some detail.
