What are your deciding factors for choosing one platform over the other?
I am curretly in a process of moving from OpenHab as I wanted to try something new and HA’s lovelace bought me xD
my OH instance was running off of rPi 3B+ for the past 2 years. Never had any issues and / or dead SD card. Currently, as I am preparing for the HA plunge (and want the OH running concurrently till I am confident enough with HA) I am investigating possible hardware approaches. Sooner or later most of you migrate away from rPi because of the SD card issues, but some choose the rPi for the sake of having it on a separate device.
My setup is currently very tiny, but will grow as soon as I feel more comfortable with HA.
Currently I have following devices on which I can run HA:
Raspberry Pi 4 - 4GB
NAS (Celeron N3455 / 8GB RAM / RAID 10)
one of old laptops:
i7-720QM / 8GB / 250GB SSD / HD5650 - con: it is a behemoth of a laptop (19")
Core2Duo T7250 / 2GB / 250GB HDD - pro: it is way smaller than the above one
I know that I can currently run HA on any of those without issues, but looking more futureproof, NAS / laptop seem to be better choices.
With NAS the disadvantage is that with every OS update, HA instance will be down for up to 10 minutes (yes, it can sometimes take that long to shut everything down, update and do the checks).
The best solution, I feel, would be to run HA on a NUC - but what’s the point (besides the size).
Next to best solution is one of those 2 laptops - but just how powerful do these need to be?
Or will the 4GB rPi be sufficient?
SD card failures won’t be a problem - as the config (whether rPi / laptop) will be regularly backed up (maybe even Rsync-ed) with the NAS and copy of the most important data is also kept offsite, on my private VPS.
Are there things I forgot to consider? What are your thoughts on this, guys?
