USV / USP for Raspberry PI 3
Hey Guys,
has someone tested a USP (in German USV) for a Raspberry 3? I found this on Amazon “https://www.amazon.de/S-USV-basic-Einzigartige-Raspberry-Modelle/dp/B00XYKDJAG/ref=sr_1_1?ie=UTF8&qid=1501523062&sr=8-1&keywords=raspberry+pi+3+usv”
And anyone knows a good Case for the Raspberry? Because at moment i have already the z-Wave Addon in der Raspberry so there will not a enough space in the closed case for a another Addon.
Greetings Milcho

In my opinion its cheaper to plug a powerbank at the raspberry and also at the power cord. like a buffer…
230V -> powerbank -> raspberry pi
what do you think?
But an usv should be as smart to safely shutdown the pi. I managed it via a Powerbank and an wire from the power plug to the gpio input to identify a short interruption or longer one to safely shut down the pi.

Yes, i know that you mine, you just need a Powerbank with “Pass-Trough” for powering the Raspberry and charging the Powerbank, but with this you cant shutdown the Raspberry and this should work with the Modul i posted… the only reason why want something like this is because the SD-Cards are very weak and dont wanna loss the card by a Energy crash.(i have backups but it sucks

Thanks for the links …
Sadly that nobody has tested this Module that i posted. 
You are right. A powerbank doesnt support shutdown!
Is it required to have the shut down function done by the power bank?
There is a little program that can do this as well but than you need to have a Ethernet cable attached. If the network goes down and there is still power on the pi, it will shut down.
I don’t remember the name of the program but should be easy to find
@rikki78
this is a good idea. This can be done with pimatic-ping and pimatic-shell plugin. So if the usp has juice for 4h you could shutdown with a rule like when gateway is absend for 3h then execute “sudo shutdown now“ The problem is the pi will not start automatic after shutdown.
