Thank you, interesting read. I came to a similar conclusion as you at the end of your article: it gets pricy real quick, so I opted for the self-hosted NAS and use hetzner storage for backup. I was surprised how easy it is to surpass the 100GB.

But besides hardware and maintenance cost, it costs roughly 5€/month for electricity.

Sounds like a nice setup. I’m jealous :D

But shouldn’t that only be a 1.3kWh surplus with the fridge drawing 30W*24h=720Wh?
