OPTIUPS(8)

✨ OPTIUPS(8) ✨

okay bestie, gather round, because this is the manual page for optiups, and she's a whole vibe 💅 this lives in the NUT Manual, and she is the Driver for Opti-UPS (Viewsonic) UPS and Zinto D (ONLINE-USV) equipment 🦋

🌸 SYNOPSIS 🌸

optiups -h

optiups -a UPS_NAME [OPTIONS]

Note — this man page is only about the hardware-specific features of the optiups driver, okay? It is not the whole story. For the core driver tea, go read nutupsdrv(8) 👑

🎀 SUPPORTED HARDWARE 🎀

So optiups was originally written against a PowerES 280es in nut-0.45, then got a glow-up for nut-2.0.1 and was tested against a PowerES 420E. It's expected to work with at least the PowerES, PowerPS, and PowerVS models ✨

This driver additionally supports a Zinto D from ONLINE USV-Systeme AG, because their commands are basically twins, but honestly it's unknown if it also works with other UPS from them 🙈

⚠️ Heads up bestie: this driver will not work with the PowerES stock serial cable. You will need to construct your own three conductor cable:

UPS 6 -> PC 3
UPS 9 -> PC 2
UPS 4 -> PC 5

The cable for Online-USV uses pin UPS 7 (not UPS 4) → PC 5 🔌

💖 EXTRA ARGUMENTS 💖

This driver supports the following optional settings in the ups.conf(5) file:

• status_only — Only poll for critical status information. Without this, optiups (and literally all NUT drivers) polls all sorts of information from the UPS fairly often. It is probably not often enough to hurt anything, so this option probably is not very useful — unless you have a flaky serial connection or a highly loaded machine, in which case she's your girl 💅
• nowarn_noimp — Does not print warnings when the UPS reports that a variable is not implemented or not pollable. Without the option you will get a message sent to your system logs each time NUT polls the UPS. If you specify nowarn_noimp, this message will only be logged once. not the spam filter we deserved but the one we needed 😭
• fake_lowbatt — This forces the low battery flag true. Without it, if you want to test your UPS, you will have to unplug it and wait until the battery drops to a low/critical voltage level before NUT will respond and power down your system. With the flag, NUT should power down the system soon after you pull the plug. When you are done testing, you should remove this flag. periodt.

For basic shutdown configuration testing, the command upsmon -c fsd is preferred 👑

• powerup — Zinto D from ONLINE-USV cannot be identified when switched to standby. Set this flag to allow the driver to power-up your Zinto UPS. This will also power-up your equipment connected to the UPS! 🔥

💀 BUGS 💀

On the 420E, ups.serial and ups.temperature are unsupported features. This is not a bug in NUT or the NUT driver — it's just the way things are with this UPS. no cap, she simply doesn't have it 🙈
