IMPORTANT!

You have to change the hyperlink to the configuration page seperately on every house, read How to change configuration page address.

Welcome to the BuildIT project documentation!

This wiki contains guides and very useful links that were used to make this project a reality.

In addition, this wiki contains solutions for the most likely errors and problems that a developer faces when working with the project.

Logic diagrams

Command sensors - diagram that shows how home-assistant gets data from custom sensors (command_line functions or programs ran by command_line)(used for PIRs, DHT22)
RFID - diagram that explains how the RFID input gets read into the home-assistant interface.
Configuration page and configuration(.yaml) - This diagram explains how data gets from the configuration page (written in PHP) into home-assistant and its configuration file.
Command switch - this diagram shows how command switch works. (used for LEDs/fan/doors/curtains)

Controlling elements and sensors

AM2302 (wired DHT22) with RaspberryPi
Controlling fan with raspberry
Controlling LED through Raspberry pi's pins
Controlling stepper motor with python script
Light resistor sensor
Getting readings from PIR with home-assistant
Reading PIR value with python script
RFID reader
Getting information from the card or tag with python script

Hardware

Images of the house and its components

Home-assistant

Starting home assistant
Difference between trigger and condition
Homepage (frontend.html) location
Homeassistant configuration(.yaml) location
Homeassistant source location

Raspberry pi

Accessing Pi as Super User from WinSCP
Mysql and php to raspberry
Reading from root .homeassistant folder with PHP

Database

Database - here you can find the design of the database.

Passwords

Raspberry pi - user: pi ; password: raspberry
SQL - server: localhost; user: root ; password: raspberry
Homeassistant - we disabled password on homeassistant, but if homeassistant asks for password, it is "buildit"

Troubleshooting

No such file or directory
xampp call to undefined function mysql_connect() solution
"could not open file /dev/i2c-0 or /dev/i2c/0"
