Network-controlled power switches/relays?

[Joshua Judson Rosen]

Anyone have any experience with ethernet-controlled power relays?

I have a situation with a couple of embedded Linux appliances I'm working on,
that are deployed hundreds of miles away from me, and I need the ability
to power-cycle one of them remotely. Looking for some sort of remote-controlled
AC outlet or relay (relay could be an 120V AC relay or a 12VDC relay, 
actually...).

Need one that I can control from a shell login on the other Linux machine
at the site, e.g.: a socket interface I can drive with netcat or the like,
a web interface that works with w3m or curl, SNMP Any of those would be 
fine.

I see a lot of different devices on Amazon that look like they might require
an iPhone or Android device running some proprietary GUI app on the LAN,
but I'm having trouble telling which are worthwhile and which will be a waste 
of time.

Suggestions?

Not sure if you are looking for rack-mount or what your price range is, but
at $dayjob, I a have a few rackmount ePDU G3 Managed from Eaton.
http://powerquality.eaton.com/Products-services/Backup-Power-UPS/Eaton-Managed-ePDU.aspx

I have users accessing these remotely, most commonly via SSH X11 forwarded
Firefox. It has a telnet/ssh interface, which is very obtuse to use, but I
did manage to get it to work. It does only support dsa host keys
apparently, which newer OpenSSH versions will complain about and make you
use an ssh_config option to enable. My users wanted to do some automated
power cycling, and I've successfully gotten that to work with SNMPv3.
Definitely more of an enterprise product, but has been working out for us
despite a few bumps.

We have an ancient device on the BLU server. We keep it on the local LAN
and we access it from one of the other systems . I looked into a PDU a few
years ago at algorithmics. We chose a non connected system. I believe that
Tripplite and APC have several models.

[Tom Buskey]

I had used a web based PDU with ~ 6 outlets and you could toggle them
individually.  I wish I could remember the brand/where I got it.  It was
under $200, maybe closer to $100 and a great deal.  I think it was a
Cyberguys thing.

There are other PDUs that can do that.  eBay might be the only way to get
one under $500.

Some UPSes can toggle power per port.  They can certainly turn everything
off.  Networked ones do so via SNMP/web/telnet/ssh.

At work, we have a WTI unit that will toggle power.

Re: Network-controlled power switches/relays?

[Mac]

Just had the experience of designing a multiple outlet web switch.

JAVA/Browser UI with python/RaspPI controller.

In this case I had some serious in rush current issues for a couple of
devices being controlled.

Ultimately switched to SSR's that were rated at nearly 10 x the current
rating of the devices to avoid welded contacts or fried SSR's.

It works, but I'll probably re-write the software with a custom GUI and
skip the web sockets for udp.

Might want to take a look at the sonoff switch modules. Basically a
wifi-controlled relay you can flash them with different firmware. Dirt
cheap, too!

Use these all over the world.  Have three in the arctic.  Work great,
inexpensive!  Network ping restart.

The one they're holding in the video, the Web Power Switch Pro
, looks
like the one I had in a lab with WiFi added.  Price is similar.  I'd get
one again if I needed it.

I have some of those android app wifi ones from tp-link at home.  The app
is Kasa and someone had a linux script to control it.  It's not secure.  I
might use it seasonally, but I'm not sure I'd want to put my servers on it.

Web power switch has a secure web API.  I think there is a Android App.   I
use a C# API myself... pretty simple code.

I have some wifi adapters from TP-Link that have an Android App, Kasa.
That's not secure IMO.  I don't think they're worth getting even at home
for that reason.  The only good thing is that someone hacked a script to
control them w/o their cloud.
