Has anyone used a UPS with a Raspberry Pi when running CumulusMX?
The only thing I have found is the UPS PIco from PiModules at http://www.pimodulescart.com/shop/item.aspx?itemid=17. This claims to give up to 2 hours of working for a PI and automatically switches back to the mains when that is restored. It seems to solve the problem of keeping CumulusMX going during a power outage if I'm away from home for a prolonged period.
Any thoughts/suggestions please?

Re: UPS for Raspberry PI
I have mine plugged into a 700VA UPS along with my router, but it's not a UPS specifically designed for a Pi. Since I switched from a PC server to the Pi we haven't had a power outage longer than a couple of hours, so I don't know how long it will keep it going - quite some time, I expect.
Our desktop PCs are connected to a separate, more powerful UPS, but that's just intended to keep us going for 20 minutes or so, so we can close down cleanly.

Thanks for the information. I really need something that will allow the Pi and therefore CumulusMX to keep going during an outage and not need restarting when the mains are re-connected.
We are visiting family in Australia after Christmas and I don't want to miss any data whilst I'm away for a few weeks.
The UPS PIco looks OK but I'm a bit out of my comfort zone with some of the instructions they give for setting it up with a Pi.
I think I'll get one and try it.

Re: UPS for Raspberry PI
A 6V motorcycle battery would make a great UPS.
Kept 'trickle charged' it will supply 5+ hours at 1A and cost < £20

Re: UPS for Raspberry PI
Any normal reputable UPS will keep it supplied. The power switch over is all handled by the UPS, that's its job.. The Pi should see nothing, just power up to the point where the battery runs out if the outage is too long. When outage ends it puts the Pi back online and starts recharging to be ready for next time.Graham64 wrote:Steve

PI power draw would be minimal I'd think, a 500, 700 or 1000 would give it quite a few hours of runtime. (Divide the Pi watts into the UPS watts for a very rough estimate )
(My wife sells these things up to half a megawatt or more, BIG ones. And desktop 500-1000 watt units,)
If you want a good one buy Eaton or APC, the Chinese knock-offs have poor sine wave generational, ( low frequency stepping ) and slow switch over. Also somewhat unreliable. Preferably buy a line interactive, it will step in for minor fluctuations as well, very efficient.
I'd get my wife to sell you a good one (Eaton) but you're on the other side of the world.
