Don't forget to share what you have discovered and tested here in wiki 😃

SerialSend5 55aa00060005650400010276 Forward
SerialSend5 55aa00060005650400010074 Reverse
SerialSend5 55aa00060005650400010175 Stop
Additional Possible Commands (Untested)
SerialSend5 55aa000600086802000400000032ad Should open curtain to 20%
or
SerialSend5 55aa000600086602000400000032ab should open curtain to 20%
Commands may be necessary to start opening after setting the percentage.
SerialSend5 55aa0006000501010001010e -> Should enable auto close mode
SerialSend5 55aa0006000501010001000d -> should disable auto close mode
If you send the direction changing too fast (from open to close and vice versa), the motor may be blocked by built in failsafes. Consider sending delay (1 sec) before changing direction. For example, these commands work and don't make the motor block:
Backlog delay 10; SerialSend5 55aa00060005650400010276 open
Backlog delay 10; SerialSend5 55aa00060005650400010074 close
Backlog delay 10; SerialSend5 55aa00060005650400010175 stop
