So.. it happened SD card build questions

So I’m going to rebuild my system and was wondering if there are any advantages between the 32 or 64 bit versions of HA.

I’m installing ona Pi4 and will be using Z Wave devices a few Shelly’s and a Sonoff or two… nothing exotic save possibly my Reolink cameras

Depends on the RAM in the Pi I believe. 4GB is the max that 32bit can address. 64bit can access ~16 million TB.

I’ve forgotten what size my Pi is… is there a way to check visually?

I don’t know.
But just shove Ubuntu or something on a USB stick and do a live boot (ie without installing). And you’ll be able to find out.

Thanks Rob!
