Homey Heating Scheduler How to use

Where can I find directions on how to use Homey Heating Scheduler? I have several questions about the setup and use. It seems so easy, but I make it so hard. I am trying to set it to different temperatures at certain times of the day. Do I also need to set it up in flows to make it work? After you set it up, how do you turn it on? You can not use flows for this. Example: Turn the heat to 68 at 7:00 am, then turn it to 65 at 10:00 pm. Once again, make the directions as easy as possible Thanks for the help

For starters you can open the app page at homey.app store;
You’ll often find (links to) a howto, and links to dedicated app topics, or other ways like github.com
