HS4 device doesn't show in HS4 event action "Control a device"

[puma]

I have HS4 device that shows in HS4 device list.The device has 6 "features".
Same device does show in HS4 event trigger so that I can trigger events depending on device's / features value.
Same device or any of device's features however don't show in HS4 event action "Control a device" . I can't control the device or features. What's wrong here? Any ideas ?

How was the device and its features created? A root device isn't controllable. Under Status/Graphics, make sure the features have controls defined under "Edit Controls".

Thanks. That was it. It works now after I edited controls. Very stupid and user unfriendly IMHO.
