I just wanted to create this topic because I kept getting this error:
Failed to call service cover/open_cover. unknown
Failed to call service cover/close_cover. unknown
AlCalzone from Z-Wave JS was so nice to add the configuration for this device to the project, however still I was getting this error while trying to control the FGR-224.
Turns out, you need to calibrate the Z-Wave device first, then re-interview, then it works.
Calibration can be done by setting [4-112-0-150] Force calibration to 3 after calibiration is completed it will display 1.
I would not have been able to figure this out with the help of AlCalzone, better said: he figured out basically everything, all credits go to him.
