hardware replacement upgrade (lemmy.world)

I have been running HA on a Pi3b for a few years. It's been a bit flakey the last few months so I'm looking to upgrade to a Pi5. After the replacement I expect to add more items and maybe phase out the Insteon for more Z-Wave.

I plan to "start from scratch". I use an Insteon hub for most switches and 2 garage doors, some Z-Wave switches, a few generic lamp plugs, 2 cheap Matter bulbs, and Alexa for my wife. Maybe 20 devices or so. The only automations are 2 sunset items and one that links a Z-Wave switch to a insteon switchlink. What will be my major pain points for rebuilding?

Or is there a straightforward method to migrate directly?

What kind of problem will this be for my Nabu Casa subscription? Alexa integration?

Or do I try to build first, then decomm the old one? Won't that cause a conflict?

You can just create a backup and restore it on the new host. Pretty simple. It'll basically be like you just kept running your old host.

This. If you have any sort of set up - just do a backup and restore. All the configuration, automations, etc. will come across exactly as it was, including your subscription set up.

I’ve migrated from a Pi to a mini pc so it works between different platforms too - there I had to reinstall add ons but it was still generally an easy migration.

Can confirm, went from a pi4 to a pi5 with nvme drive, backup from the old host and restore to the new host. You will need to download the backup to your computer first.

Excellent. Thank you a lot.

One thing you will probably have to deal with though: if you have USB devices assigned by their address, you will just need to go in and set them to whatever the new address is on the new host. Should be pretty simple.

Ooo. My Z-Wave dongle is USB. Good to know. Thanks.

Yeah, upgrading to a Pi5 was super simple for me using the backup method. After the swap, I had to pair a few devices again and fix a couple automations to reflect the changes, but that was all. I'd definitely go that route vs start from scratch unless you are experiencing some serious problems.

I don't know how cheap pi5 are where you are but I would advise to have a look at one of those small pc with n100 or n150 processor. They are really low powered (close to pi5) and you will get a more powerful device. They cost around 150€ (even 100 on sale).

That's a fantastic option.

Also something used like a NUC or a little miniPC could be great as well.
