If i were to buy a Raspberry Pi for this - worth splashing for the 4GB?
They suggest 2gb here Install Home Assistant - Home Assistant (home-assistant.io)…

Just wanted to bump the above question - with no sign of lockdown ending soon thinking I’ll go the Pi route but wondering if 2GB sufficient?

I have the 8Gb version. Just thinking for the future.
