ESPHome YAML snippet for Eliwell EWPlus 974 EO Modbus interface
# This snippet is incomplete, make sure to fill the rest to your needs
# This snippet is made with the assumption:
# - You are using the ESP32-C3 SuperMini
# - You have a 5V <-> 3.3V TTL converter hooked up on GPIO0 and GPIO1
# - GPIO1 (converted) is attached to the RX pin of the EWPlus (TX side of ESP32)
# - GPIO0 (converted) is attached to the TX pin of the EWPlus (RX side of ESP32)
# - Your EWPlus 974 EO is set to use Modbus with device address of 1 (check your device settings)
# By github.com/NathanAdhitya
# Author note:
# - The datasheet parameter table addresses seems to be accurate

Downloads student submissions in Google Classroom programatically and group them into folders based on name of students.

This script helps you (as a teacher in Google Classroom) download all the files submitted by students.
I'm not sure where I partially copy pasted this from, but some parts have been modified by me to suit my needs.
Have fun!

Rangkuman TIK

Nathan, 24/02/2021

Teori Dasar

HTML adalah singkatan dari Hypertext Markup Language.
HTML dirancang pada konsep bahasa markup SGML, yang merupakan standar untuk membuat dokumen menggunakan tanda (markup) seperti paragraf, list, heading, dan lain-lain. (dalam HTML, markup yang digunakan adalah seperti p, li, h1)

Di dalam dokumen HTML, terdapat tag atau tanda. Tag adalah penanda awalan dan akhiran dari sebuah elemen. Tag dibuat menggunakan kurung siku <...>, dengan pasangan penutup menggunakan garis miring (/) di depan nama tag.
Untuk diingat: Tidak semua tag memiliki pasangan. Secara umum, mayoritas tag memilki pasangan penutup.

a google classroom to discord webhook. WARNING: not the most efficient method (look: push notifs [can't afford that]). this takes (amount of classes * 2)+1 requests / run.

KNOWN THINGS THIS THING WON'T ACCOUNT FOR:
- Google servers cutting the amount of data returned is not accounted for.
- Updates to existing announcement/course works
- Support for class material?
