With the price of these little buggers dropping, I am finding more and more the nVidia Jetson nano attractive as a self contained platform to run openLuup/z-way/Home Assistant and all the HomeKit/Alexa bridges of course with a couple of sticks for zigbee and zwave. Because of the included GPU, it can do faster video processing and be a development platform for further ventures into AI and a potential alternative to the rPi4... Enticing for <$100?

Im very frustrated with my new pi. I have 2 pis running on ssds with no sd card great. But for the life of me I can’t get it to boot from the exact same model of ssd that works on my other pi. I also can’t get the new pi to boot from old known working sd card. I tried burning new image onto ssd, known working image, in fact the only way it will boot is with the noobs card it came with. I thought pi3s didn’t have any firmware it was all software, but thats all I can think of. I am stumped. No, I don’t want to boot off sd card. Is it a bad pi? I did every single step multiple times. I know how to do this, ive done it twice. What’s going on?

Is there any way I can run my pi on portable battery power for short period of time? My plan is to take that zway server to each of the zwave devices rather then the other way around. Does that make sense?

I just upgraded one of my pi’s from sd to ssd. Huge speed increase. Stop what you’re doing and do that now if you haven’t already

All my pi are using msata

@DesT I don't even know what that is. Is it faster than ssd?

No it is a format of SSD. It is short of microSATA. It is SATA in the form form of a small PCB card which you insert into a socket. Very similar to the current M.2 SSD standard except it uses the SATA communication bus which is much more limited that through the direct PCIe. You did well with the SSD. That’s what I did too for all my devices. It was the idea behind extroot for the vera. Beyond speed it is really a reliability improvement. Can read my post on storage here which explains why.

Might as well ask here, what do you all think of the 4’s? I’m worried about heat. My 3s have been rock solid. Which is more than I can say for their more expensive brothers.
-
I am concerned about the rPi4 heat and peak power consumption. They seem to require more power to boot so regular 2Amps power are not enough any more. At this power level, I don't quite see their advantage over the atomic Pi which is cheaper and more powerful and more flexible in terms of software and hardware. If you already have a 3+ then no reason to change. If you feel the need to change, I would probably not choose a rPi4. There are better SBC choices now.

|-<:)Vis USB or some other funkiness? I was looking at this the other day, but my Pi's don't so far need any more speed (Volumio, XBMC and minidnla) but I can imagine a Z-wave device might well benefit....
<tan> I upgraded my 2015 iMac last weekend, with some trepidation. Power on to a stable desktop went from over 7 minutes to 59 seconds

@prophead Cool.

A, its a pi

We (me and also PointPub Media) stop using rPI and we switch to rock64 and rockpro64 (pine64.org)

As @rafale77 explain it's like SSD but you can find little board that you can mount on your rPI and use a mSATA disk!
-
@DesT Do you have a link for this piece of hardware, I have no idea of what it looks like?
-
It's not "like" an SSD. It is a SATA SSD in a different form factor.
Here is an example: https://www.amazon.com/dp/B07MWSKWCT
These are light years faster and more reliable than eMMC and SD Cards.
Not the simplest to use on a rPi... It's much easier to go with SATA for these. -
@rafale77 Thx's, I can see it's a good solution but the adaptor card is nearly 4* the price of the SSD or there an another solution?
-
@DesT mentioned this because he is not using a rPi but a pine64 /rock pines which do support these forms of storage natively. I would just get a regular 2.5” SATA SSD with a USB to SATA adapter. The same thing I used to extroot the vera.
I actually have all of my rPi run that way. They all have an SD card with a boot loader only and then loads the OS from the external USB SSD. -
@rafale77 Nah I'm talking about my raspberry!
On my pine64/rock I'm using eMMC directly on board but all our raspberry are using something like:
OR something like
-
AND I will suggest to boot directly FROM THE USB without using a SD Card to boot!
-
This is how I run my Z-way Pi 3B+, i.e. boot directly from the SSD.
I have connected a 2.5” external USB case that I put an old SSD into. The Pi seems a bit finnicky when it comes to USB drive chipsets, the first one I tried did not work.
Pi 3B+ is ready for boot from USB out of the box, which is why I choose it. You just copy the .img onto the SSD and you are good to go.
The speed after the SSD swap is quite a bit faster. The major upside I hope, should however be the reliability. -
This is not what you’re serving the forum from, is it?
