Raspis just aren't long-term reliable. My Raspi4 node died twice and completely corrupted its ssd each time. They would almost certainly do better with a UPS, but at that point the arguments in favor ...
100% A node based on a raspberry pie is not long term sustainable. Especially if you want to do more than just run the core. If you want to do lightning, and mempool, lnbits, fulcrum and any other kind of add-on, you definitely need a better hardware.
