Best Raspberry Pi to purchase for OH 3.x


I’ve been using OH for over 3 years now and I’ve come to a cross roads where I need to start migrating to OH 3.x from OH 2.4 based on Amazon Binding not getting upgraded with the recent “LastVoiceCommand” channel. I’m currently running on a Synology NAS and I would like to dedicate a device specifically to OH.

I’m looking to get a Raspberry Pi for this migration. I’m looking for the best setup possible to purchase with some advice from the group. Price isn’t a factor of my decision. This platform migration needs to run for at least 3 years.

My OH 2.4 configuration is quite big so performance is key.

Any advice on this would be appreciated. Any links to recommended purchases would be helpful.

Still run mine on the Rasp 3 PI but I see memory constraint. I have a few other 4s sitting around but haven’t migrated over yet. Definitely you should go with more than 1 Gig of ram, at minimum a Rasp 4 with 2Gig of RAM.

Get a RPi 4 with 2 or 4 GB, whatever you get hold of easier given current supply shortage.
Get a second one as a spare right away, and get a card reader + secondary SD card.


Hi Markus,

How’s this one?

Appreciate your feedback.

Best, Jay

As I said: 2 or 4 GB. Not 8, there can be issues.
A 16GB SD card is large enough, anything larger is wasted. Get a “endurance” SD card model.
