Home Assistant is the single most popular home-automation platform in 2026, and Home Assistant OS (HassOS) is the easiest way to run it. It’s a dedicated Linux distribution that boots on a Raspberry Pi, handles Z-Wave, Zigbee, WiFi smart devices, and pretty much everything in your smart home. The first step is getting HassOS onto … Read more

You have a 128 GB SD card with a working Raspberry Pi install on it. You want to migrate to a smaller, cheaper, or more rugged 32 GB card.

I archived a Raspberry Pi IMG file to my NAS in 2023. Pulled it out to restore in early 2026, three years later, and SHA256 didn’t match the hash I’d saved alongside the file.
