My RasPi(Raspbian 9.4 (stretch)+livimdi 1.7.4) cannot communicate with ZWOASI EFWmini as follows. I have installed dependencies, sudo apt --fix-broken install, and cp udev rule based on ASI website. (Last year, it did worked with jessie+libindi_1.4.1)
My final goal is to do this on PizeroW, but did not work. Then I retried it on Pi3B, but not worked. Thank you for your kind advice.

#My script
export LANG=en_US
sudo indiserver indi_asi_wheel &
sleep 3s
indi_setprop "EFW.CONNECTION.CONNECT=On"
indi_setprop "EFW.CONNECTION.DISCONNECT=Off"
jobs
indi_setprop "EFW.FILTER_SLOT.FILTER_SLOT_VALUE=1"
indi_getprop "EFW.FILTER_SLOT.FILTER_SLOT_VALUE"
