Hi,

I want to buy an UPS (probably 1500 or 1700VA) that can be managed (idally from linux via a script but web interface is also acceptable) and which can power cycle individual sockets.
I don't need too many sockets but at least 4-6 would be fine.

Would you happen to have any recommendations? I'm flexible with the price.

Thanks.

Hey, have you listed a price, location and how much shipping would be to other parts of New Zealand? Also if you are asking for a PM make sure your Privacy settings allow your account to receive PM otherwise people can't contact you.

instead of a smart UPS, you could consider blade server infrastucture. you get to power on/off all the blades and network switches individually. a cheap hp c3000 one going on trademe right now even: http://www.trademe.co.nz/computers/servers/servers/auction-581361273.htm

I want this for my home, to power cycle the adsl modem via a text message :)
I think it would be cheaper (and easier) to look at a board with 240V ac relays that achieves this thing. I wonder if such thing exists in a retail form and not necessarily home made.

Hmm I'm not sure you'll find what you want all-in-one - perhaps a UPS + ethernet controlled power strip

Lol seeing so many suckers buying old Bladecenters and asking for colocation these days. When we mention the power prices to the customer and how much its likely to cost we get an interesting reaction :P

This is exactly what I was after, thank you.

If you are looking for some smart power switching, I would highly recommend the Raritan Managed Power Strips.

These are a little smarter than a typical Managed PDU.

For example you could have a Modem/Router connected on one of those ports.  Tell the PDU to ping an external ip address regularly, and if that ip address does not respond it can automatically reboot that outlet (or you can add delays, alarms and many other events before it reboots the outlet).

Plug in a dry contact sensor into the sensor port, connect it to a door switch in a rack, connect a Webcam to the USB port, and when someone opens the rack it automatically takes some photos and emails them off or uploads to an ftp site.

Have a look at http://www.raritan.com/products/power-management/px-2000/

The Eaton Evolution UPS has individually controlled outlets on the rear of the unit and can be networked with a web card.

Hello,

I refused to pay ~ $350 so I built my own :)

I already had a Raspberry Pi so took advantage of the GPIO port. I initially tried to use some jaycar 5vdc relays but they weren't working properly as the pi only provides 3v3 and it was a hit and miss.
So I ordered a Sainsmart 8-relay board for $12 odd delivered. Took a couple of weeks and it arrived. The relays are 5V but the trigger is designed for 3V3.

From here, there are two options. The sainsmart relays support up to 40vdc (I think) or 240vac. So, if can tehnically be used directly into the 240v leads.

I wanted to take the more cautios approach (and not so messy) so I bought a 4 port extension lead from Jay Car with a radio remote control that can power on/off each individual socket. It comes with a 12v battery but it works great from the a 5V pi port (the range is definitely smaller but I don't really care as they are quite close). So, I opened the remote, soldered some leads where the buttons are and took the other ends to Pi's GPIO and with some basic bash scripting, it works "as adevertised".

It's obviously not as pretty as a 'retail' version but it was a nice little project. It's clean as the 240V power is not touched and the pi is actually controlling the small remote control. The Pi and relays can be hidden anywhere and the extension lead can be used anywhere around the house.

One drawback is the lack of any feedback so you don't have a status (eg: socket is on/off) and you don't know if the reset actually worked (I have some IP cameras so if ping timeouts, it worked). But for a personal-use it's exactly what I needed.

If you have any questions, let me know.

Cheers.

McNulty
