This is my Home Assistant configuration, I'm currently running 0.75.3. It is installed on a Raspberry Pi 3, using the old All in One installer (effectively a manual install like this, on a 16 GB card, that I've upgraded to Python 3.6. I use a Razberry board for Z-Wave control. To limit the risk brought by SD card corruption (a known risk with Pi3) I store the Home Assistant database on a USB stick, and use a multi-port USB charger with sufficient power for all ports, but have left one unused. The power cables are short, and high quality, to minimise issues with voltage drop. Of course, I also take many different backups to reduce the risk of losing anything.
