@yashvind Thanks for the Tag
The issue with the shades stopping at random positions is firmware related and you need to check the version you are on. If it's below 11.03 what essentially happens on most hubs and sometimes on wink as well (you were just lucky) when a command is sent and the shade is in motion or just about to start motion from a command it already received or it decides to repeat another z-wave command in the z-wave network a bug in the firmware caused the motors to think they are overloaded with power and forced them to stop (with a red light on the motor) to prevent damage to the motor. When this happens it can be any where from mins to an hour for them to respond again directly to the hub or if you move the shade the opposite direction using the remote and try again it will work.
I find that SmartThings and Hubitat tends to repeat commands in the z-wave network which is when this happens.
Pm me if you need further help. Just double check the firmware version on the shade first.
