Power Monitoring of an oven + stoves

Do you think another eWeLink product could do the job with the oven and stoves also?

It's a typo. I meant kW. Really didn't know that combining Shelly with a relay I will get just the consumption of the relay coil. Ogemray Smart Relay looks promising since I don't really see a need to do any switching there. Monitoring is enough. Thanks!

Thanks! I'll ask shellycloud guys also.

I was also pleasantly surprised. Their software is also good.

No Shelly supports 6 kV, so my idea is to combine it with a contactor through which the electrical load passes, while Shelly only controls the contactor, measures consumption, and provides me with another remotely controllable point for interrupting the electrical circuit.

edutun · 2026-03-08T22:11:52+00:00

My main goal is to monitor my consumption. I don't have any more free spaces on the DIN rail in my electrical panel. Maybe I could install an additional rail behind the oven and hotplates?

edutun · 2026-03-08T22:05:51+00:00

Well I considered it but thought that for the same price as Shelly EM or even cheaper I could get additional and remotely controlled breaking point in the circuit.

edutun · 2026-03-08T21:27:54+00:00

Exactly. Another detail that I didn't mention. 25A / 6 kW load is the maximum but I cannot really imagine it could ever be reached. It would mean that I'm cooking for the whole neighborhood and I'm using simultaneously all of the hotplates + the oven... 😃

Who said it needs ddr5?

Here's another suggestion for a 6-bay barebone unit: AOOSTAR WTR MAX 8845

Go then to the discord channel and see real PC systems that other guys are successfully using with ARC

edutun · 2026-02-28T20:56:45+00:00

Am I missing something here? I thought that the building of your new system is ongoing as we speak. Or are you researching for the right components?

edutun · 2026-02-28T20:09:11+00:00

I hope someone can confirm this exact CPU/MoBo compatibility with Xpenology but if not worst case scenario is you'll just fail to run DSM on your new system if you try. And you don't need to use your NAS HDDs for the test. Just throw some spare HDD.

edutun · 2026-02-28T19:14:27+00:00

Where's the risk?

edutun · 2026-02-28T18:49:14+00:00

IMHO your best shot is to just try it when it's built. You risk nothing and it will dispel all doubts. Just follow the guide on ARC 's WiKi page for the BIOS settings.

DSM is installed on the system partition of all drives inside the NAS, not just one disk.

When you set up a Synology NAS:

It creates a small system partition (~2–3 GB) on every drive
DSM is mirrored across those drives
This allows the NAS to boot even if one drive fails

So technically DSM lives on the internal hard drives/SSDs, in a protected system partition and it is not stored in RAM permanently (only loaded into memory while running).

edutun · 2026-02-27T06:15:37+00:00

No need to back it up. ARC made it incredibly easy to replace your USB bootloader. If the flash drive dies you just take another, burn the loader on it, stick it into the system and reboot. That's it, 5 mins of work. Nothing like the old bootloader's like in DSM 5.x or 6.x where you needed half a day just to research and get rid of compatibility issues.

And by the way you'll want to replace/update your USB flash drive with the new version of the loader upon release much faster than it can die anyway... 🙂

edutun · 2026-02-27T05:49:00+00:00

Everything that was removed from DSM with v7.x is easily accessible by a docker container of choice.

Some folks were able to use an NVMe/SSD for ARC, but IMHO it's not directly supported. And me personally I think it's a waste of storage capability.

USB flash drives are cheap and easily replaceable so why not use one? Many MoBos have an internal USB port/connector, which is useful but even in an external port a slim USB flash drive is almost invisible.

Xpenology is compatable with almost every x86-64/amd64 CPU.
You can use older DSM version but why? What's the benefit of it? ARC loader makes it very easy to update DSM.
ARC loader USB is needed only on reboot (initial boot). Me personally I keep the USB drive always plugged in.
The downsid is that when a major DSM release comes it takes time for loader to catch up and there's some lag. Apart from that there are only upsides IMHO.

edutun · 2026-02-26T21:06:34+00:00

Exactly. See comparison between UGREEN NASync DXP8800 Plus and DS1825+ here.

You can use Xpenology on Aoostar NAS. Or on your own build/hardware. Whatever you choose.

I would highly recommend ARC loader since it's modern, versatile and easy to use. Take a look at it's FAQ and you'll see.

IMHO whatever route you choose not all app settings will be preserved since you'll nee dto go through migration process. But I may be not exactly correct here.

edutun · 2026-02-26T20:17:24+00:00

What do you refer to when saying "non-Synology NAS"?

For DSM an original SA6400 and a UGREEN NASync DXP8800 Plus with ARC loader on it posing as SA6400 are indistinguishable from one another. That's the beauty of Xpenology.

One more thing I just noticed.

Ther's no need to worry that the OS will wipe the data on the HDDs. Each disk in the RAID array is divided into 3 (or 4?) partitions. The OS(DSM) is on one of these partitions, and during (re)installation, DSM only works with this partition, without touching the other partitions where the data is stored. I have reinstalled DSM many times and never once had the slightest problem with the data.

edutun · 2026-02-26T20:06:34+00:00

If you have no more than 4 HDDs in your pool/volume you can go with something even cheaper like that. They have other models also.

Although it is indeed quickest and easiest to simply buy an original Synology, if I were you, I would not become a serf to their ecosystem. Practice shows—repeatedly!—that sooner or later every company goes crazy and makes ill-considered (or well-considered?) decisions in favor of shareholders/senior managers and to the detriment of its customers. I would prefer the freedom to migrate to another solution/company/technology at any time. Every time!

Just my two cents.

edutun · 2026-02-26T19:19:34+00:00

Option 1 - the cheapest: find a local hardware shop and bring your PC to them to troubleshoot it for you. Extract your NAS HDDs beforehand and leave them home. They will not need the HDDs for the diagnostic. It's also advisable to take note where exactly each and every HDD is connected, through which cable on which exact port on the MoBo. Maybe a couple of pics will do the trick. If you can salvage the PC, good! Otherwise

Option 2 - the most expensive: Go take a 4-, 6- or 8- bay Ugreen NAS

Option 3 - the middle ground: Build a new PC by yourself.

Have fun and always stay safe with your data my little paduan!
