Folder Usage Report Scripts

DISCLAIMER: README and some parts of the scripts generated by AI.

A lightweight, self-contained daily disk usage monitoring and reporting system for Linux servers. It tracks folder sizes over time, calculates daily and 30-day deltas, generates a clean HTML report (optimized for email), and can send it automatically.

The system consists of two main scripts:

• A data collection script that records folder sizes into a CSV log.
• A report generation script that processes the CSV, computes deltas, strips common path prefixes, and produces a professional HTML report.

This is a way to have a binary sensor from a single code in the RF Bridge in ESPHome.

We have a binary_delay to configure the delay between on/off in the binary sensor. some_sensor is a template(dummy) Binary sensor that gets updated by the RF Bridge when a code is received.

The action is a script, so if multiple codes are received, the timer counts againts the last one.

This is a simple example on how to interface with a TLC5973 IC to dim LEDs in Raspberry Pi.

It uses SPI to generate a pulse train with precise timing.

In Raspberry Pi, the SPI may have some inter-byte delay, which makes this useless. More here: https://www.raspberrypi.org/forums/viewtopic.php?t=211152

I'm using go-rpio to manage the SPI device.

The idea to use SPI came from this repo: https://github.com/mik4el/cc1350-swim-thermo/blob/b2fdb54a940e18911959a5e1778ca7fc06915a11/software/tlc5973_spimaster_CC1350_SWIMTHERMO_tirtos_ccs/spimaster.c
