 Everybody wants their home automation to be stable and most people install a dedicated RPi, i.e. they don't install any other software there that may interfere with proper openHAB operation.
 Reasonably so, this is our clear recommendation. Saving another 100 bucks is not worth putting the reliable day-to-day operations of your home at risk.

 Cards named "Endurance" can handle more write cycles and will be more enduring under openHAB\'s use conditions.
 Prepare to make use of the [SD mirroring feature](openhabian.md#SD-mirroring), get a 2nd SD card right away, same model or at least the size of your internal one, plus a USB card reader.
