wireless UPS stats

[bjlockie]

I have a USP for mt voip phone and modem.
Does anyone know of a gadget that will let me access the usb wirelessly so I can get the stats remotely?

Does the manufacturer have a program suite?

APC does, but I don't much like it, because it is bloated (~8 processes) and I rarely use it.

I use a linux desktop so the answer is no.

What do you want to monitor, AC power fail and battery voltage? You could use arduino and a voltage divider and just wire it in. You can also plug a relay into a wall wart (plugged into the wall, not the UPS) and use that as an AC fail alarm point. When the relay gets power the value is 1 and when it loses power the relay returns to off and value is 0. Or vise versa if you connect it inverse. I personally like to make my alarm points normally closed, that way if something happens to the wiring it will cause an alarm.

You could measure current using a shunt and op amp too, I have not done this myself yet though but been looking into it as the cheap ass panel meter I bought is garbage and does not display the correct values. In my case I'm monitoring a large battery bank though but would work the same for a simple UPS.

For the wireless you could either have the arduino connected to a small wifi capable computer (like a raspberry pi with wifi dongle) or maybe use some kind of wifi or xbee shield. (not familiar myself with how they work - the rpi way would be easier imo)
