sudo ln -s [path-to-project]/water_level/scripts/water_level.service water_level.service
sudo ln -s [path-to-project]/water_level/scripts/water_level.timer water_level.timer

Next go to and make symlink to auto update script:

cd /usr/bin/
sudo ln -s [path-to-project]/water_level/scripts/update_water_level.sh update_water_level.sh

Now start the services.

sudo systemctl daemon-reload
sudo systemctl enable water_level.timer
sudo systemctl start water_level.timer
