Hi there!
Anyone around here who tried installing the node on a RPi or who can share some thoughts about Debian installation in 32-bit based systems? Also experiences with a 64-bit (e.g. RPi 4B) would be appreciated

This is definitely going to be my node option. Looking into Raspberry Pi options now. They are pretty cheap.

Yes they are! Let us keep up to date about any progress ;)
Hi, I’ve been running a Raspberry Pi node for a few days now. I have the 3B+ model which comes with 1GB RAM and a Cortex-A53 CPU. I’m running it on the official Raspberry Pi OS 32-bit.
HOPR recommends at least 2GB of RAM for a node, but for now my Pi node uses between 100MB - 130MB tops, even after days. Also CPU usage is usually low, spiking up only to 50% max (of one core, that is). This all may of course change as soon as the network grows, cover traffic starts, or staking starts. We’ll see.
The only issue I had is that it wouldn’t open any channels on its own, even when promiscuous mode was enabled. I was able to manually open channels though.
One thing to watch out for is the HOPR log file gobbling up all disk space. Sometimes it writes 20MB in a day, other times 500MB in a day. I only had a 4 GB card laying around, that made the whole setup a bit difficult, I recommend at least 8GB.
