A Home Assistant AddOn to schedule switches and lights on a weekly base in a visual way without coding. You can keep all the schedules in one place and add/change in a few clicks, even in your mobile app.
You can add the URL of this page in your "add-on store" as a new repository. Click refresh and you will find the add-on "Simple Scheduler" listed.
The add-on is very easy and intuitive (or, at least, that's what I hope) Once installed, open the GUI or click on the sidebar (if you choose to add to it) Just click on the round plus button in the bottom right and add your first schedule. Choose the switch/light from the dropdown, fill the ON time (in 24 hours format, as suggested) and select the weekdays. Do the same for the OFF time and click "save". That's it! It's not mandatory to add both ON and OFF time. You can leave one of them empty if you don't need it. For example, you want to turn off a light every day at 22:00, but you don't need to turn it on. You can then edit any of the schedules with the icon at the end of the row. You can also choose to delete it or disable it (the schedule will stay there, but it will not be executed until you enable it back)
The default text language is English. They are very few words. If you want to translate them, you just need to take a look at the configuration section of the addon. Rewrite the words you would like to have in your language and restart the addon. For the weekdays, as you can easily understand, only the first two chars are used.
Every schedule (or row, if you prefer) is a JSON file stored in the [share/simplescheduler] folder under the SAMBA share. This gives the chance to the data to "survive" to an addon upgrade or reinstallation. You can easily backup and restore them in case of failure. In the same way, you can (accidentally?) delete them. So be aware of that.
