In the event of a blackout, you can already detect the grid frequency going down. The grid frequency can also be easily determined and thus i build an early warning system, with the help of a WioTerminal (from SeeedStudio), NodeRED, a Raspberry Pi and Telegram - I show you how!
If you just want to be warned without building anything, you can (even easier) subscribe to my Telegram channel (german):
