Hi
Can you provide some Infos about Performance?
Is esphome working fine?
I have setup armbian bullseye with omv 6, attached a jmb25… sata card with a 18tb data hdd.
Running zfs on a Single disk and Currently all fine so far.
Next step is extending to a zfs mirror and let it be the backup server as it was planned for.
Nevertheless the 21 watts with running hdd are really nice for a permanent setup, running home assistant.
So two things to get that done:
Knowing about the performance and flashing a working spi uboot to use a ssd, as emmc will probably die very often with home assistant running.
