<div dir="ltr">On my raspbian buster RPi3's that run nut, no problems with the stock nut packages provided so I wouldn't expect problems with your RPi4 once you get the cable and configs sorted out. I use the RPi3's as nut-servers to monitor and manage my Tripp-Lite UPS systems, the other local systems run nut-client and communicate with the RPi.<div><br></div><div>--Larry</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Jan 7, 2020 at 6:28 AM Gene Heskett <<a href="mailto:gheskett@shentel.net">gheskett@shentel.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;border-left-color:rgb(204,204,204);padding-left:1ex">Greetings all;<br>
<br>
Does nut build on an r-pi4b?<br>
<br>
I have an r-pi4b running one of my cnc machines and the power bump <br>
performance due to the size of its psu and the fairly rapid start time <br>
of my standby generator, does not allow a full powerdown restart to take <br>
place, leaving the pi in a crashed state.<br>
<br>
I've purchased a factory refurbed cyberpower ups rated at 650 WA which I <br>
intend to figure out a way to hang it on the machine to power the pi <br>
only, which has a 25 watt 5 volt psu running it. With no connection to <br>
the pi other that putting cyberpower in the line cords path, it should <br>
run the pi for 30 minutes, and the standby will generally start in <br>
around 5 secs. So the problem should be solved.<br>
<br>
But it would be nice to be able to monitor it. So, can nut be built to <br>
run on an armhf platform? Mmmm, possibly silly Q, its available in the <br>
raspbian buster repo's. So I had apt install it.<br>
<br>
But the installer failed to start it, not surprising because its not been <br>
configured yet nor has whatever cable cyberpower needs been connected.<br>
The apt install log:<br>
pi@rpi4:/media/pi/workspace/rpi4-kernel $ sudo apt install nut<br>

So, is there enough help in the man pages?, or do you see any <br>

Thanks all.<br>
