request to add support the ARMAC Home 1000E 1000VA 650W UPS model

[Dragonek-303]

NUT support would be very useful. I want to be able to use it with Raspberry Pi OS Lite.

Some Armac models are known in NUT code base. Can you post logs please - what have you tried, what the driver debug said?

You would want nutdrv_qx, its armac subdriver was last significantly touched in NUT v2.8.1 release. If your distro ships an older version, consider building your own replacement, see https://github.com/networkupstools/nut/wiki/Building-NUT-for-in%E2%80%90place-upgrades-or-non%E2%80%90disruptive-tests

[Dragonek-303]

I won't send the logs yet because I'm planning to buy this ARMAC Home 1000E 1000VA 650W UPS. I want to know in advance if the basic monitoring, i.e. battery status, will work.

[jimklimov]

I see. In this case we won't know until someone tries and posts the results. From precedent, it is likely that nutdrv_qx would work, unless they've created some new device series internally unrelated to others (which tends to happen too, over decades on the market).

To prepare for the worst-case scenario, maybe look for a shop where you can return the little-used goods due to incompatibility, or put on the white-hacker hat to sniff/debug what is missing in the dialog handling for the device, and complete the missing bits. That would likely start with preparing a build environment per wiki page linked above, so you can tinker...

Support wrote to me: Good morning,

Hardware-wise, the Home series models have a completely different design.

[jimklimov]

Well, I can't comment more, it is a coin-toss then. Can you ask them which protocol these series talk - if that would be a dialect of Megatec Qx (where "x" is some number like 1 or 2 or 6, most commonly)?

[Dragonek-303]

They wrote to me: Good morning,

The logical protocol is Megatec. Attached is a list of commands, but please note that some of them may not be supported by the device, as this depends on the manufacturer of the communication chip.

"Network UPS Tools: Megatec Protocol information"

What goes around, comes around :)

That page seems to be a copy from April 2001 state of Russel Kroll (NUT originator) personal page.

[jimklimov]

In the light of the above findings and statements, chances are good that NUT would support this device.

@Dragonek-303 Have you bought it? Does it work?

[Dragonek-303]

I apologize for not responding. I decided I didn't want to bother because it wouldn't work, so I bought the PowerWalker Vi 1000 stl, which is the one that's supported (at least partially). Currently, I'm not sure how to configure my Raspberry Pi to shut down when it detects a low battery level, as most guides use the Raspberry Pi to shut down other devices.
