[Nut-upsdev] UPS CYBERPOWER CP1300EPFCLCD MISSING FROMCOMPATIBILITY LIST

Sat Mar 10 21:57:42 UTC 2018

Hello Charles, 

Nice to make your acquaintance. J

Thanks for your detailed reply. I appreciate it greatly.  I want to learn.

I have read and tried to get my head around the information you have provided but as a lot of it is new to me I have some questions.

1.       As I am connecting the Cyberpower CP1300ePFCLCD to my Synology NAS DS216+II via USB cable.  

This makes the NAS a NUT Server and the NUT driver is part of the NAS operating system which I have no control over

In the UPS section of the Control Panel, the NAS is reporting the following:

a.       Manufacturer = CPS

b.      Model = CP1300EPFCLCD

c.       Status  = Connected

d.      Battery 100%

e.      Estimated Battery = 3390 seconds 

The UPS is only Lightly loaded (about 7%) as I want a long run time due to frequent power outages.  This USP runs my NAS, Modem/Router, Ether switches etc.  It gives me plenty of time to start my Inverter Generator.

2.       In the Information Tab of the Control panel The NAS reports the USB device as CP1500AVR UPS. 
I have raise this difference of names with Synology but they have told me this is normal.  I don’t know but my instinct tells me it’s not?

My question is if you release a new driver(s)/packages, does Synology have to do an update to the DSM for this to change? I would think so?

I am assuming that as the NUT server, it would be the dominant device.  
My other devices that are running the nut-client (eg Raspberry Pi’s) would be subservient to the NUT / NAS server?

3.        ups.timer.shutdown: -60 and  ups.timer.start: -60

I was assuming these values as correct as the LCD panel shows the battery run time as 60 minutes and the estimated battery time of 3390 seconds from the NAS is close enough and this figure does vary depending when and where I read it.
I have simulated a MAINS FAILURE by turning off the power and the clients reported that they were on battery.  I left it for about 5 minutes and all seems to be doing what it should.

I have set the Time before Diskstation enters safe Mode to 15 minutes on the NAS UPS panel.  As the estimated battery time is 60 minutes the this gives me enough time to start the generator but only if I am at home!  Hopefully, if I am not, and the mains outage continues the all will be gracefully shutdown on low battery and according to the HELP below it should all restart upon mains return.  Well that’s the theory at this stage.  When I am more knowledgeable I intend to test it fully but at this stage I want to be sure my planning is valid. 

This is from the Synology Help:
________________________________________________________________________________________________
Safe Mode

When the Synology NAS enters Safe Mode, it stops all services and unmounts volumes in order to prevent data loss and shut down (halt for EDS14) safely when the UPS device runs out of power. By default, the system enters Safe Mode when the UPS device starts running low on power. You can also specify the amount of time before the Synology NAS enters Safe Mode when power failure occurs. However, if the UPS device reaches low battery before the specified time, the system enters Safe Mode immediately.

In situations when the Synology NAS shuts down during Safe Mode, it will automatically turn on when power is restored if you have enabled the Restart automatically after a power failure option (located at Control Panel > Hardware & Power > General).
_________________________________________________________________________________________________

4.       When I update the packages on my Rasbian Jessie  on my Raspberry Pi’s I usually use the apt-get update && apt-get upgrade Commands.  
If you release a new driver/package will this pick it up?  I am guessing it would by the looking at the URL below?
According to this URL https://packages.debian.org/jessie/nut-client When I look at this I am running 2.7.2-4. 

Anyway, I hope I have not been too verbose but as I said I want to learn.

Kind Regards

Ron

Thanks, we'll add that to the list. We have a few updates queued up for when we cut the next release, and one of them is a similar model:

    <http://new.networkupstools.org/ddl/Cyber_Power_Systems/CP1500EPFCLCD.html> http://new.networkupstools.org/ddl/Cyber_Power_Systems/CP1500EPFCLCD.html

Note that the EPFCLCD models seem to have some of the same issues as the PFCLCD models:

    <http://new.networkupstools.org/ddl/Cyber_Power_Systems/CP1500PFCLCD.html> http://new.networkupstools.org/ddl/Cyber_Power_Systems/CP1500PFCLCD.html

There are enough Cyber Power quirks that they get their own category in our issue tracker :-)

I'm not sure there's much we can do about this one. The UPS publishes a dummy value (sometimes shows up as 16V, sometimes the same as the nominal voltage), but I have heard that even the CyberPower software doesn't have a way to report the battery voltage.

> and I have seen values up to 265V I have checked the OUTPUT VOLTAGE on the UPS front panel and it’s showing the correct value, that is if the input voltage is 242V then the panel is showing 242V as output voltage.

It should be possible to fix this one at some point:

We just got a contribution of some code to be able to patch the descriptor data coming back from the UPS, but we would also need to adapt that to be specific to the Cyber Power devices. Not sure if that will make it into the next release, though.

Your NAS firmware may take care of this, but you will want to make sure that your shutdown delay is greater than 60 seconds - the UPS only takes values in whole minutes, but NUT represents time in seconds (and rounds down, unfortunately).

Let us know if you have any other questions (be sure to use "Reply All" to include the mailing list).
