Just tried to set this up as part of a new install for renewing a Let's Encrypt cert. I can't seem to get the thing to work; I don't have the option to send a notification checked, however it will not let me continue without setting a notification device or message. Since I don't have a device with the app installed I can't continue...

Can you Update line 34 please? The line reads: "name: Minutes untile restart" and contains a typo. it must be: "name: Minutes until restart" (no more e after until :D
