One-to-one mirror for every drive might be excessive… just a 1 or two drive parity system should be fine for most home use cases.

You should have e a backup after all

Oh sorry, must have missed that part.

Source? Trust me bro?

Nice domain!

Was it you that I have asked if you were the same Dark Alex from the PSP custom firmware scene?

For me that was literally the first unsponsored Amazon find for the term “router UPS”

Search for “router UPS”

For example there is one from APC “# APC Back-UPS Connect 12V DC 36W - CP12036LI”

Sounds interesting, do you share the project progress somewhere?

+1 on the zfs replication. That’s what I use as well with a 3 node cluster. Gives redundancy and high availability without building a ceph cluster (which needs 4 nodes if I remember correctly)

No you are right, the m720q will fit an 2.5” and also m.2 drives.

Sorry, what I meant is that they will not fit 3,5” hdds, let alone multiple ones.

12th Gen is definitively neat, but overkill for what you are doing. 8th or 9th gen is fine. 16gigs is fine, 8gig would also work

I really like the Lenovo m720q line of mini pcs (used/refurb) but they will not fit an hdd.

/edit: I mean an 3,5” HDD. They will fit one 2,5” HDD fine.

It will still sync to all devices. And if you have an always on vpn to your home network, there really is no need to expose it to the public

I have one installed on a raspberry pi 5 with NVMe adaptor.

In this regard: here is a comparison of all the Lenovo tinys: https://github.com/a-little-wifi/TinySecrets

Zigbee2mqtt can do scenes, no problem.

The only thing you miss is the hue app.

But you can buy a 10-20€ zigbee stick and connect them directly to home assistant. No hue bridge or account required.

Do you want the data to be only stored once or twice? Or would it be an option to sync everything? This would be the easiest. Just set up 3 individual servers, set up syncthing between them, done.

It would mean that all server need enough storage though.

Matter itself is just the protocol, not the wireless standard. There are lots of matter over WiFi devices, for those you don’t need this additional adapter, as they will connect to your WiFi router.

Thread is a wireless standard which is almost like zigbee, that is why there are some adapters that support both.

But thread border routers are also a thing in lots of devices. For example if you have an Apple TV, this can be used as a gateway with home assistant without additional hardware.

Matter is not really big yet.
