I have one pi (rpi 4b) that I still use. I have it in an Argon One V2 case for the daughter board that lets me boot from an M.2 SATA SSD. I got tired of the corrupted SD cards. It’s actually reliable now.

Anyway, I mainly only use it because in the event of a power outage, as soon as power is restored, it automatically turns on. If I’m not home, I can SSH back into my network and send a WoL packet to my actual server to turn it back on.

The pi also runs:

• Scrypted so I can view my ring cameras in the Apple Home app and so I get the “someone is at the door” notifications on my Apple TV
• Pi-Hole
• Pi-VPN
