Configuring Home Assistant to run off of a USB drive in a incompatible Raspberry Pi

 A problem with the earlier generations of Raspberry Pi's, especially the Pi 1 and the Pi 2 up to version 1.1, is that these cannot be configured to boot from an external USB storage device.

This is a particular relevant limitation for a number of reasons, including the fact that relying on an SD card for most of the storage needs is a solution that may have limited endurance.

The later versions of the Raspberry Pi (RPi 2 v1.2 and upwards), already offer some form of allowing external USB media to boot the operating system.

Improving an RPI 2 based Home Assistant server for reliability and performance

For some time I have been using the same Raspberry Pi 2 v1.1 as the infrastructure for my Hass.io instance. It proved to perform quite reliably over the approximately 18 months I have been using it 24x7. From that time during approximately 1 year I used the same SanDisk Ultra XC I 64 GB MicroSD card:


Just for precaution I have later switched to a similar card, a SanDisk Ultra HC I 32 GB, and moved my Hass.io installation onto it:
