Hey there,
I use 13 Fibaro Roller Shutter (FGR-222) since 2016 to control my vetetian blinds with my old smart home controller.
Today I switched them to HA and then realized, that it is quite difficult to control the tilt option… 
After some tests I managed to find a solution for my problem.
These are my configuration steps:
- Change report type to “Fibaro Command”
- Mode: Venetian blind
- (Turning time, if necessary)
- Start calibration
In automation I use the following (example: group of blinds, position closed, 20 % tilt → my position is twisted)
alias: Jalousien - Süd 100/20
