Thanks for that reply

Do you know of any ressources or documentation that describes this control via the backend in more detail? and which commands that can be run, and how it would be set up - like where would I run the script from?
Thanks in advance
A more exact approach to stop/start your miners at sunset/sunrise would be:
a) install command 'at'
sudo apt install at
b) create the following files:
echo 'systemctl start apollo-miner' > /etc/sunr
echo 'systemctl stop apollo-miner' > /etc/suns
touch /etc/atsunrise.sh
touch /etc/atsunset.sh
chmod +x /etc/atsun*.sh
c) create a shell script which is called via cron every day early in the morning
# crontab entry:
# run the script everyday at 01:00 am
0 1 * * * /etc/sunr_suns.sh
create the script /etc/sunr_suns.sh
# /bin/bash
# script name: /etc/sunr_suns.sh
# (don't forget to make the script executable - chmod +x /etc/sunr_suns.sh)
#
# retrieve current sunrise and sunset times at a specific location
# (don't forget to change your country/city)

#
echo $(wget -q -O- https://www.timeanddate.com/sun/germany/munich | grep -oE 'Sunrise Today.{35}' | awk -F\> '{print $3}' | cut -c 1-5) > /tmp/sunrise
echo $(wget -q -O- https://www.timeanddate.com/sun/germany/munich | grep -oE 'Sunset Today.{35}' | awk -F\> '{print $3}' | cut -c 1-5) > /tmp/sunset
#
# assemble the command line structure for the at command:
#
echo at $(cat /tmp/sunrise) -f /etc/sunr > /etc/atsunrise.sh
echo at $(cat /tmp/sunset) -f /etc/suns > /etc/atsunset.sh
#
# run the scripts
#
/etc/atsunrise.sh
/etc/atsunset.sh
