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?
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.
