✨ RIELLO_SER(8) ✨

okay bestie, gather round 💖 this is the manual page for riello_ser, and it's literally the driver for Riello UPS Protocol UPS equipment that you hook up over serial port connections. section 8, system administration, main character energy, no cap. 🎀

🌸 SYNOPSIS 🌸

riello_ser -h

riello_ser -a UPS_NAME [OPTIONS]

Note 🫶 okay so important thing: this man page only spills the tea on the hardware-specific features of the riello_ser driver. for the core driver deets, you gotta go read nutupsdrv(8). iykyk 💅

🦋 SUPPORTED HARDWARE 🦋

riello_ser supports all recent Riello UPS and Aros UPS models which use the Riello UPS GPSER and SENTR protocols. slay ✨

Older Riello UPS products? not supported. sorry bestie, it's giving deprecated 💀

💜 EXTRA ARGUMENTS 💜

depending on the make and model of your UPS, you might need to tweak some settings (peep ups.conf(5) for the full vibe check):

• localcalculation — when this is enabled, the driver will calculate the values of battery.runtime and battery.charge "locally" inside the driver itself. this is for those Riello models that be giving incorrect values in their hardware readings, or none at all 😭. this "local calculation" is done according to nominal battery capacity, nominal battery voltage, actual battery charge, maximum and actual UPS load. fr fr, it's doing math on your behalf 🧮✨

you may wanna also configure default.battery.voltage.low and default.battery.voltage.high in case the built-in default range (from 10.7V to 12.9V) does not match your hardware, or give a shot to default.battery.voltage.nominal (e.g. 24) if your device does not serve that either. 👑

Note 🎀 Lead (PbAc) battery charge graph is not linear, so the guesstimated charge value may not be perfectly accurate. however, it should be good enough to determine battery actual status and roughly estimate the time it can still power the system. close enough honestly 💅

Warning ⚠️ This keyword may be deprecated in future releases of the driver, in favor of runtimecal and other settings which it requires (as seen in nutdrv_qx(8), blazer_ser(8) and blazer_usb(8) drivers). not me warning you about the future 🔮😭
