Lens-Cover with RC-Servo, "sunwait" and cronjob

[Pedritoprint]

I hope, that is the right place for my question, related to allsky-camera i'm building up.
I'm testing my Servo-Control which works fine manualy and with cron-job by using "sunwait"-SW but in crontab i have to write down the used parameters like Long/Lat/Angel of my residence as values, for example:
30 15 * * * ./home/pi/allsky/src/sunwait-src/sunwait wait angle -8 set 47.0N 8.0E; /home/pi/cover/cover_open.py;

• but this job don't wait till sunset with angle -8, it runs the called programm immediately after cronjob starts (here 15:30) and
• is there e opportunity to use the parameters we have set in CAMERA_SETTINGS finding at location ./etc/raspap/settings_xxx.json?
  I read hints in several forums but found nowhere useable hints to use in crontab.

@Pedritoprint One way to do it is to have cron call a shell script which contains something like:

cd ~/allsky
source config/config.sh
./sunwait angle $(jq -r ".angle,.latitude,.longitude" ${CAMERA_SETTINGS})

Is this what you were looking for? I copied it from the Wiki page on "Angle and sunrise/sunset Explained ".

Your hint is perfect thanks. At first i used also this wiki-hint but as command in crontab and this doesn't work but now with the shell-script...perfect. I'm happy and now, i will complete my camera and install it in ma backyard.
Camera is working, dewheater with meteo-sensor is working and last not but least also now the lens-cover for daytime works. (i removed the IR filter on sensor)

@Pedritoprint Glad it worked out. If you didn't notice, the ./sunwait should either be sunwait or src/sunwait.
