Home automation

Summary

What are you going to build? What does it do? Why are you excited to build it? Home automation is an increasingly important part of connected house. It makes daily life easier by automatically performing small and simple tasks. Unfortunately, the various brands on the market generally only offer expensive and not very flexible product range. i want to work on a solution which makes home automation accessible to all by using a raspberry pi, ESP32 and some sensors and actuators.

Plan

1. centralautomation hub using rasberry pi and apache server -first inplan to develope a central hub using rasberry pi and apache server which will connect to the other modules over the web using wifi and esp 32 boards

• will make use of - 1 x |RPI4-MODBP-8GB|-the main rasberry pi board. 1 x | Orange Raspberry Pi 4 Advance Kit |- will be used to set up rasaberry pi, provide it with necessary power and connect it with the software and wifi, 1 x | 40 Pin Red GPIO Extension Board for Raspberry Pi|- will enable me to easily connect the parts from rasbrerry pi kit on the board without harming the rasberry pi board

they all wil make use of esp 32 boards boards vwill be reused for newer modles as the modules are more compared to the esp boards the modules are more.

modules can be increased or decresed as per need,time and avaibility of hardware components and further modules can be easily added in the future. they will be connected o the central hub built using rasberry pi and can be accessed through web for now and can be manipulated theough mobile phones in the future.

As all the codes are open-source, to enable me to appropriate the modules in future.

i will be refrancing the following builds-
