🎀 NAME 🎀

metasys — the driver for Meta System UPS equipment. that's it, that's the whole vibe 💅

🦋 SYNOPSIS 🦋

metasys -h

metasys -a UPS_NAME [OPTIONS]

note bestie 📌 this man page is only about the hardware-specific stuff the metasys driver does. for all the core driver tea, go read nutupsdrv(8) — she's the main character, this page is just her very specific friend 💖

🌈 SUPPORTED HARDWARE 🌈

so like, the metasys driver was written using the "Meta System UPS Protocol Rev.1.12", which Meta System themselves very kindly supplied 🥹 iconic of them honestly.

the driver should support all the common features of these UPS models:

• HF Line (/2) 1-8 boards 🎀
• HF Millennium (810, 820)
• HF TOP Line (910, 920, 930, 940, 950, 970, 980) ✨
• ECO Network (750, 1000, 1050, 1500, 1800, 2000, 2100, 2500, 3000)
• ECO (305, 308, 311, 511, 516, 519, 522, SX, SXI) 💜
• ally HF (800, 1000, 1250, 1600, 2000, 2500)
• Megaline (1250, 2500, 3750, 5000, 6250, 7500, 8750, 10000) 👑

that's a whole roster, fr fr 🫶

💅 CABLING 💅

the cable you need is a standard pin-to-pin serial cable, and it needs at least pins 2, 3, and 5 connected (on a DB9 connector). that's the whole requirement. go raid the cable drawer, bestie 🔥

---

⭐ EXTRA ARGUMENTS ⭐

plot twist: this driver supports no extra arguments from ups.conf(5). nothing. zero. she's low maintenance like that 😌

---

💀 BUGS 💀

real talk: this driver has only ever been tested on the Meta System HF Millennium 820 and the ally HF 1000. just those two 🥲

and if you've used it with any of the other UPS models listed above? please please please send in info about it — it is really welcome, no cap 🙏✨
