Network of arduinos

Hello guys,

I want to control different objects with different arduinos and then combine them somehow to connect them to my home internet wifi and then i will be able to control them from my cellphone. I have attached a simple diagram. Can someone suggest what should i use to connect all the different arduinos.

I can not connet them via cables as they are all about 25-30 meters apart from eachother.

In the diagram i have mentioned ESP8266 But if you guyz have any better option then please tell me.

In simple words if i were to make a home automation system and lets suppose in my home there are 10 rooms and for controlling every room i have installed 1 arduino per room. and i want to access all the arduinos from my cell phone. how do i connect all the arduinos.

Regards

i want to access all the arduinos from my cell phone. how do i connect all the arduinos.

A simple way would be to have each 8266 host its own webpage, and just use a browser on the phone.

But for that i will have to connect to the wifi 8266 i want to connect all the 8266 to one wifi

Get the 8266s to connect to your WiFi AP/router.

Suppose you configure one of your ESP8266s as a server and all the others (and your phone) as clients then they can all make GET or POST requests to the server to send it data and your phone can make a different request so it can see the data.

I have to say I reckon it would be much simpler to build the server on an RaspberryPi.

How do i make a server from RaspberryPi which will connect so many wifis and do you know of any project of similar nature if yes please link.

There is a 'HelloMesh' example for the ESP8266 in the IDE.

Never used it, but it can link ~100 WiFi devices according to Espressif.
Lots of "ESP Mesh" info on Google.

Hi,
Can you please tell us your electronics, programming, Arduino, hardware experience?

On possible solution is to use an home automation server software such as openHAB.

Or perhaps https://nodered.org/

That's what web servers do.

If you are thinking of using an RPi have a look at the Python Bottle web framework. It makes it very simple to get a server running.
