CSC Jinja Custom Template

Referring page: Custom Sprinkler Controller (CSC)
This is a custom jinja template I created for my sprinkler controller. The file is named irrigation_time.jinja and it needs to be saved in the config/custom_templates folder.
More info on using custom templates is available here.
