UPS with Speed Shift, or PowerD

[xantonin]

I have a UPS connected to my pfSense box via USB and i want to have it go into a very conservative power saving mode during a power outage on UPS power only. It seems the best way to do this is with PowerD since it has options for battery. I can't find anything similar for Speed Shift.

I guess I'm just looking for confirmation on this. Speed Shift sounds better for performance overall but if I can't get it to be dynamic during a power outage, maybe PowerD is better?

Hmm, I'm not sure powerd can 'see' the UPS power source. The battery there is usually for laptops where you might want a different power setting when it's unplugged.

[provels]

Probably a moot point. Pretty sure powerd should drop the CPU to a minimum freq no matter the power, battery or line, if it's not under load. My 2.4 GHz system sits at 400MHz at idle. Try monitoring the Dashboard stats on/off battery.

@stephenw10 Oh, that changes everything. I always thought it was for UPS power when on battery backup.

I need to see what it recognizes the current status as, any ideas? I'll try digging around a bit...

[stephenw10]

Pretty sure it's this:

[24.03-RELEASE][admin@4200.stevew.lan]/root: sysctl hw.acpi.acline
hw.acpi.acline: 0

Though that has to be supported by the BIOS.That should indicate that 4200 is running on battery which clearly isn't true!

@stephenw10 said in UPS with Speed Shift, or PowerD:

sysctl hw.acpi.acline

Hm that didn't work for me.

Bummer, I found my own answer:

[24.03-RELEASE][admin@pfSense.home.asevigny.net]/root: powerd -v
powerd: unable to determine AC line status

[stephenw10]

Yes, I only found one system here that reports that sysctl. And it probably shouldn't!
