Running openHAB in the cloud using a Raspberry Pi 0 W as a local USB Server

Think twice if you really want to make yourself, your home and reliability of your local functionality dependent on your internet connection and ‘the cloud’, which - in Kai’s terms - is “just other people’s computers”.
Even more so given it obviously isn’t a no-brainer and chances are your setup will introduce errors you wouldn’t encounter on a local server.

Move to use openHABian instead, it has ZRAM to mitigate SD wearout, plus an elaborated backup concept.
