HYTHYGTEMP(4)

📦 version 11.0, in nixpkgs unstable

okay so bestie, you just opened HYTHYGTEMP(4) — the manpage for hythygtemp — and honestly? iconic sensor-driver behavior. let's go 💅

🌸 NAME 🌸

hythygtemp — Driver for IST-AG HYT-221/271/939 sensor chip via I2C bus

✨ SYNOPSIS ✨

hythygtemp* at iic? addr 0x28

🦋 DESCRIPTION 🦋

okay so the hythygtemp driver provides measurements from the HYT-221/271/939 humidity/temperature sensors via the envsys(4) framework. literally sensor data with main character energy. 💖

the hythygtemp addr argument selects the address at the iic(4) bus. yes bestie, that's the address-picking part. ✨

the sampling interval can be changed through the sysctl(8) node hw.hythygtemp0.interval. that's where the knob lives. 🌸

and not me finding out that the sensor chips can be reconfigured to respond to other addresses than the default value of 0x28 by external utilities, like for example the pkgsrc/sysutils/hytctl package. 😭 iykyk.

🎀 SYSCTL VARIABLES 🎀

here are the sysctl(3) variables it provides, bestie:

  • hw.hythygtemp0.interval — Defines the sensor's sampling interval in seconds. It defaults to 50 seconds. ⏱️
