I tried to use the scripting tool but again, I don't know how to connect the local python script with the Dome Scripting driver. let me explain: this would be my script in order to switch the GPIO Pin on the RPi 4B: import RPi.GPIO as GPIO import time GPIO.setmode(GPIO.BCM) # GPIO number RELAIS_1_GPIO = 17 GPIO.setup(RELAIS_1_GPIO, GPIO.OUT) # GPIO Mode GPIO.output(RELAIS_1_GPIO, GPIO.HIGH) # on, opens the roof wait(20000) # wait 20s to be sure it is completely open ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The "open.py" script is like: #!/usr/bin/python # # Open shutter script for INDI Dome Scripting Gateway # # Arguments: none # Exit code: 0 for success, 1 for failure # import sys coordinates = open('/tmp/indi-status', 'r') str = coordinates.readline() coordinates.close() str = str[0] + ' 1 ' + str[4:] coordinates = open('/tmp/indi-status', 'w') coordinates.truncate() coordinates.write(str) coordinates.close() sys.exit(0) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ I can not see the interaction between both scripts? Shall I integrate "my script" into "open.py" script???? Sorry for the stupid question. GunterRead More...
