Hi guys,
Do you think 2.5 A power supply from Pi3 will work fine with Pi4?
What would be the migration process? Can I just move my SD card or do I need to use backup and restore to a new raspberry with fresh home assistant install?
In the specs, guess a usb c adapter is needed ?
5V DC via USB-C connector (minimum 3A*)
- A good quality 2.5A power supply can be used if downstream USB peripherals consume less than 500mA in total.
No it won’t work.
can we make it work this way? Ideally one should be able to download HASSIO and burn it to SD, SSD or pendrive.

It would be great.
I made a feature request here:

This is great news just when I’ve been looking at upgrade options from pi 3b+, it’s now an easy choice… unfortunately it’s sold out everywhere in the uk 
Agreed, I was toying of the idea of getting an Intel NUC and running a docker container, or running it though my Synology NAS in docker.
Not sure which way I’m heading at the moment. I think the Pi4 is going to be the quickest solution for me at the moment.
Hopefully someone will test who much faster the pi 4 is against the 3 B+ (Running hassio).
I managed to do a completely fresh buster raspbian installation last night on a Pi 4 4Gb and everything seems ok using this method here:
I’m using the SanDisk extreme 32GB card which I’ve always used to home assistant and never had any problems (I do take regular file backups and sdcard images as backups).
I’m going to migrate my home assistant over this weekend so will report back.
The thing I am wondering is if I can use a usb3 attached SSD for database storage in home assistant as that is currently disabled at the moment.

Got mine today (4gb) will build and try to work out how to migrate over from my 3b
They have done a load of baseline tests online if you search, I’ve seen a few already and the bottom line is much better

The biggest obvious gains will be a slightly faster processor, 3gb extra ram and for those booting from USB a major increase in read/write processes via the higher speed USB3 port.
The processor will run hotter and for those running their boards in a case passive processor cooling will be a minimum requirement.
I’d be more interested in the new Buster OS and how it performs with HA in all its flavours.
Be prepared for teething troubles particularly with the combination of a new board/OS at the same time.
Interesting times ahead indeed.
I just did receive mine. In the Safety and User guide it also mentions an 8GB version next to the three already announced models.

Interesting.
Might wait for the 8gb version so.
Getting closer to a desktop setup rather than a tinkering board.
Would be interesting whether that bug still exist when using the GPIO pins for my zwave module and then at the same time bluetooth. currently I have to disable BT on my raspberry pi 3b, because of that.
Turns out the 8GB option is a typo, as per one of the engineers:
https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=243372&start=350#p1485310
Yup, typo. We haven’t released an 8GB version! It’s 1,2, or 4. We’ve found that 1 is best for headless, 2 for desktop (even lots of Chromium tabs) and 4 is best for dev work with big compiles.
A ha. So it is true. Don’t believe everything you read. An aspiration rather than a reality.
I wouldn’t entirely agree that 4gb wouldn’t be beneficial for headless though.
Still 4gb not available to purchase at the moment so I’ll have to wait to find out.
Let us know how you go. My 2GB is on its way, and I’ll be looking to migrate in a couple weeks.
Ideally would love a hassOS image, but I doubt that would be ready to go by then, so Raspbian with hass.io it is for now
I’m currently running Hass.io on a pi3b+ functioning as just a quiet little box humming away and not bothering anyone. It’s consistently at <20% cpu usage (typically 8%), memory is about 1/2 used of the 1G on board.
I have found the vast majority of response issues and less than perfect reliability was solved by moving from the telecom company supplied cheap wifi/router/modem to a bit more robust dual band router (read: don’t buy the cheapest out there). The issues have been network, not cpu.
I personally don’t see what an upgrade would buy me. I think I’m gunna pass on this one.
