Could anyone let me know the command to get/set the position of ZWO EFWmini? Or the way to know them.
When I put indi_getprop, Therminal replied as
connect: Connection refused

What I would like to do is take images with DSLR/EFW from Bash script like this;

sudo python3 switch3.py #waiting for START by push button through GPIO on RPi3
#set EFW position 1 <—I want this!
sudo gphoto2 --set-config burstnumber=04
sudo gphoto2 --set-config shutterspeed2=006
sudo gphoto2 --capture-image
sudo gphoto2 --set-config shutterspeed2=012
sudo gphoto2 --capture-image
#set EFW positon 2
sudo gphoto2 --set-config burstnumber=04
sudo gphoto2 --set-config shutterspeed2=006
sudo gphoto2 --capture-image
sudo gphoto2 --set-config shutterspeed2=012
sudo gphoto2 --capture-image
…

gphoto2 commands work well.

I use; Pi3 raspbian, and ZWO EFWmini
INDI Library v1.4.1 based on:
www.indilib.org/download/raspberry-pi.html

Installed udev rule(Linux) based on:
"EFW filter wheel software Manual（Linux & OSX）"
astronomy-imaging-camera.com/manuals/EFW...Linux%20OSX%20EN.pdf
