RPi 4 vs 5

[Exit2Studios]

Is there any advantage to going with an RPi 5? I have a 2GB Pi4 that I can use, but if there's any real advantage to going with a new HW, I'm open to it. I thought I read somewhere where a Pi4 is better thermally for outdoor use.

Nope, this app still runs great on a Pi3B+. Faster hardware isn't needed. I haven't looked into any thermal changes, but many people have been running the 3B+ in desert conditions in an Atelix-like box with air circulation and don't have overheating issues.

I keep getting errors on my Pi4 (2GB) that JavaScript heap out of memory, specifically with REM. This is causing REM to have issues starting and seems to reboot every 21 minutes. Could it have anything to do with using 64-bit OS?

Probably not. I am using RP4 with 64-bit OS Bookworm

Then I should probably try to figure out what is causing the following errors (I assumed I didn't have enough RAM):

0|REM | FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

I've tried adding
node_args: "--max-old-space-size=1280" to the ecosystem.config.js file to no avail (even bumped to 1280 for REM)

What is the result of running free -h in terminal ?

[Exit2Studios]

I think that error may be old, based on the command I was running and not an issue. Seems to be more stable now since I limited the space allocation.

I have a Pi5 that I'm no longer using, so I was considering moving to that as it has a lot more firepower, but I'm not sure I need it and worried that the thermals may be worse on it.
