💖 W1FIND(1) — the w1find manual, bestie edition 💖

okay so this is the manual page for w1find, part of the w1retap family of tools. if you're here you're probably staring at 1-Wire weather sensors and going "where r u tho" — same, babe. let's go. 🦋

✨ NAME ✨

w1find — find 1-Wire weather sensors 🌡️

🎀 SYNOPSIS 🎀

w1find DEVICE

🌸 DESCRIPTION 🌸

w1find goes on a lil scavenger hunt 🔍 and searches for and displays sensors for the w1retap(1) package. that's it. that's the whole job. it finds them and it shows you them. iconic behavior honestly. 💅

✨ OPTIONS ✨

  • DEVICE — this is the interface device, and bestie it can be one of two flavors: a serial DS2480 adaptor or a USB DS2490-1 adaptor. 🫶
    • for the serial route, use the serial device node — like /dev/ttyS0 or /dev/ttyUSB0 📟
    • for the USB route, literally just write DS2490-1 and it'll use libusb for the USB adaptor 🔌

🦋 EXAMPLE 🦋

here's what it looks like in the wild, no cap:

  • $ w1find /dev/ttyUSBS0
  • $ w1find DS2490-1

💜 SIGNALS 💜

the w1retap daemon accepts three signals, and every single one of them is doing the most (affectionate):

  • SIGUSR1 — makes it read all the sensors immediately. right now. no waiting. go go go 🏃‍♀️
  • SIGUSR2 — makes it print the current configuration. show me ur settings bestie 📋
  • SIGHUP — makes it re-read the configuration. refresh, reboot the vibe, start fresh 🌈

👑 EXIT STATUS 👑

  • 0 — returns 0 on success. slay. 🎉
  • 1 — returns 1 on failure. 😭 not slay.
