Two suggestions for a future update to send notifications when a station goes offline.
1 - Send email notification when a station is offline will be excellent.
But the user could choose your timezone and times that the station should be working, no need to send notification when the station is actually offline by choice.
A layout like the "power saving" tab.
2 - When this feature is working, could have an option of sending SMS too. Each SMS sent would be charged, and could be sent SMS to any country.
The webhosting company "OVH" have this feature, for example: When the user's server goes down, they send an SMS to any country. They sell a package of SMS, you buy a package of SMS to be notified when necessary.
It would be very good these two suggestions are working.

If someone needs the suggestion of sending SMS. You can do this:
When the ability to receive email notifications are working, you can hire a company to send SMS, then configure your email to any email notification that get to you, this email is sent to a system of sending SMS, and this system trigger your SMS for you.
An example is the plan of OVH SMS, you send an email to the system and re-send it as SMS.
