RPI 4B 1GB RAM Enough?

Given the general shortages at the moment, im struggling to get access to anything above 1GB.

I think you'll be fine with a 1 GB Pi 4. I would expect big Z-Wave networks and multiple users accessing the UI would increase CPU load and have a relatively minor impact on memory usage. My 2 GB Pi 4 has 1.5 GB free as shown on the top output below:

Even my 8GB Pi's are only using around 500MB even the core device that aggregates the other five Z-Way nodes with the Razberry 7 Pro boards. With that said, the majority of my automations are done in Home Assistant. So there are not many rules on the Z-Way systems themselves nor many of the apps installed either.

Raspbian doesn't take much RAM and neither does Z-Way.
