Undervoltage Reported, nothing showing in SSH to confirm

What is the problem?
Low voltage detected
What did you already try to solve it?
Test 3 different CanaKit official power supplies
Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, what kind of hardware precisely, ...)
Octoprint 1.8.7
OctoPi 0.18.0
Ender 3 with Sprite Extruder & BL Touch
Klipper firmware.

So I've been getting UnderVoltage Warnings on my Octoprint screen on startup. I've tried three different CanaKit 5v 2.5a official power supplies with no change.

I ran "vcgencmd get_throttled" in SSH and it returned "throttled=0x0"

I also ran dmesg | grep -iC 3 "under-voltage detected" and there were no results.

So can I safely assume that its a false positive at this point?

Just curious.

Can you please attach the systeminfo bundle to your next post as well the Raspberry Pi model you use.

BTW: The 'CanaKit' delivers 5V, Raspberry Pi org recommends 5.1V

Hi, here is the sysinfo bundle for my install. Thanks on the tip about the 5.1v adapters too.

It appears that during most of the starts of the Pi, an undervoltage issue was detected.

All other issues have been reported by Klipper.

Yeah, I get that message every time Octoprint starts, but is it odd that Octoprint detects it but it doesnt show up in the underlying os?

So I ended up buying the Official Raspberry Pi power supply and the Undervoltage message has since disappeared. Thanks.
