<![CDATA[Raspberry Pi3 alternative?]]>Having evolved the current Pi3/Domoticz/MySensors system over the last two years, recovered from initial SD card failures (fake/genuine) and ended up with an external portable HDD arrangement, the continued local power failures caused progressively prolongued power off reboot/rinse-repeats, until today.
And before anyone asks, yes a UPS was on my to-do list and remains there. :)
The "end Kernel panic -not syncing: VFS: Unable to mount root fs on unknown-block(8,1)" message finally made me realise I was out on a limb, I'm no Linux geek, but having already swapped a cloned SD card made me realise something HDD related went awol, and with precious little info on how to back it up it was always the weakest link that was going to break.
Beyond the intellectual disconnect to Linux, the hairy method of getting a Pi to avoid it's SD card problems was always a hope and a prayer, but has the intervening time and tech advancements promoted a more reliable solution?

@alowhum I don't think you appreciate just how far this fakery extends, so, sorry your criticism is unfair - Suppliers are playing Russian roulette offering what they believe is genuine product as the market is swamped with "genuine" fakes. My own experience was a with a big local store, and despite the usual evasion from the sales people initially they were caught with no escape when I presented the evidence. When you are selling in the zillions few can verify authenticity as they are packaged, it is a nightmare for those buying in in bulk.
The only solution I found was to go for the cheapest brand on the market as it is not the pirates' intended target. My mobile microSD is HAMA on year 2, the "genuine" Samsung blew after 2 months... Go figure...

I think you must have misunderstood the concept. I did not use a ethernet splitter and extra cable mess...
I use my router as IP supplier, 1 ethernet cable to my RPI, so I have cable to my domoticz, the RPI gets IP via cable, and if the I'm not able to ping gateway (router) then there is no power as the gateway is down.
the ONLY extra thing I have purchased is a the powerbank :-)

Indeed I misunderstood, it makes much more sense like that :)

Perhaps French, German and Dutch supplies are more reliable, but here in Romania, "Vorsprung durch fuckup" prevails

Same here in Vietnam... That's why I'll also have a wifi gateway with battery backup soon.

UPS - I went with the AD-55A, 7.2Ah cell and buck converter previously suggested elsewhere, WAY bulkier than the HAT arrangement which tempted, and may yet be deployed as a secondary safety.
What I found particularly infuriating was commercial UPS offerings mis-stating and misleading available USB current output, clearly targeting phone charging as a marketing ploy to expand their legacy constant dual voltage conversion lines without really developing anything new. Compared to these my own UPS will beat them in efficiency by a country mile as it's not designed from the ground up as dedicated dual conversion.
Aside the various HAT variants, there has not been minimal attention paid to more efficient UPSs for 5v etc devices despite an exponential increase in their deployment...
It is a little ironic really that this community has squeezed every Joule out of battery conservation on Nodes (my Gas meter is now passed year two on two AA alkaline :smile: ) yet reliance on a constant electrical supply remains for the Controller.
Perhaps French, German and Dutch supplies are more reliable, but here in Romania, "Vorsprung durch fuckup" prevails :smirk:

Do you also use the ethernet switch as a power sensor ? :D I would just use an USB splitter before the powerbank, then use one wire and a voltage divider to connect it directly to a GPIO...

There are typically many paths to same solution :-)
It was easiest for me to just copy exact same setup - why should I bother to purchase an USB splitter and spend time to setup a voltage divider and create a script that needed to measure voltage on a GPIO

It's just that it looks like a serious overkill and cable mess to use an ethernet splitter + it's own supply + ethernet cable when it can be done with less than 1$ of hardware and only one splitter + one spare usb cable. But that's just my own opinion :)

And if you want to really go for cheap and easy solution the raspi ups hat (blue PCB like in the link below) works like a charm. Compact, efficient, no extra cable. And I think the price is even cheaper than powerbank + splitter.

This method
writes/syncs modified data to SD card only on reboots.

Hourly backups are rsynced to another PI.

UPS is recommended but not a must

I'm using one of this as a virtual machine server with proxmox since 2-3 years and I'm very happy with it.

One of the vm is running pfsense so it act also as a main router / firewall for the entire Lan.

The backup of a vm is super easy 😉 but the initial setup of the environment requires a bit of Linux learning

Lesson learned, no idea yet if the database can be salvaged from the corrupted drive. Pi rebuilt on Buster with a fresh drive, just Domoticz to reinstall once UPS is running.

For 95 euros you can buy a 8-socket power plug with built in battery that can power your router, raspberry pi and other devices for about 15 minutes. You can even control it via USB. That's what I use.

It's pretty great when the power goes out and you can still use your laptop to go online as if nothing has happened.

Hi.

Maybe I misunderstood, but I don't use a sdcard on my rpi3, it directly boots on ssd.
That said for reliability, or longterm use and possible HA evolution, sure a rpi is not ideal, even the rpi4 could be quickly limited, + tests says it heats more.. (though for the moment usb boot is not released)

Because it depends on what you'll need in future, a NAS storage feature like openmediavault, cameras motion management, a media server (plex, emby/jellyfin), adblocker, IA, voice assistants etc. so many nice services to use. Then a x86 intel/amd solution might be a better solution, a lot more powerful, very well known solution. some cpu have very low tdp but I think this electricity cost variable needs to be compared to the ROI..
maintaining only one server machine might be easier too vs a swarm of RPIs.

So:

  • rpi with ssd, no sdcard. nice but limited.
  • odroid N2 with its nice passive cooling. armbian. more powerful than rpi4 I think. you need to add an emmc.
  • tv box flashed to linux, based on s905x (like the odroid n2), or RK (like the recent rk3399). The advantage is for 70-80 bucks you get a complete enclosed board with up to 4GB ram, at least 32GB emmc, and the power supply. But the inconvenient is not all boxes are fully supported in linux yet, it needs digging. so it's not really a non geek solution
  • imho my favorite solution is x86 intel/amd machine, ideally with low noise/passive cooling. some low/affordable tdp, more powerful and evolutive than others solutions. there is odroid H2 based on j4105. you can also find j4105 motherboards for 80 bucks. j5005 motherboards, used servers/proc/motherboard on ebay, mini computers like NUCs or BRIX (some are not really cheap), homemade server machine (my fav because I can pick the exact hw and brand I want).

All solution are nice, like I said it really depends how many service you'll want to run in future
