I have 2 esp32. i want to connect both the esp32 with an android application over wifi. One esp32 wifi range is about 15 meter and i connected 4 relay to it in a room. Suppose if i want to control relay beyond 15 meters then it will not communicate with esp32. i have also connected other esp32 with 4 relay in other room. so  is there a way to connect both the esp32 ? If it happens then i can control all relays from 30 meter(15 meter range of each esp32, 15 + 15=30). I want to use single android app to control all the relays. Can you also explain how to develope the android app or any available app. I have joined your ESP32 course using micropython but it is not there(Actually you should also include  esp32 automation using android app in that course).
Note: I am not using any router . And i dont want to use it now.

For that sort of application, unfortunately I don’t think Wi-Fi is a good option. Wi-Fi is meant for short range communications, what you are suggesting will not be reliable and it will likely not to work as you expect (probably 5-10 meters is more realistic).

Are you familiar with Android development or you want to use MIT App Inventor?

Sorry for taking so long to get back to you, but I was without internet for the last couple of days during a trip.

Thanks for your patience!

Thank you !! Rui for replying ….actually i have never worked on wifi. So for learning purpose i am doing this.I want to control my home appliances using wifi in my home. I have done so many homework on this now i have some idea. For this project the biggest problem is wifi range so now i am using a router to connect all the esp32. I don’t have any knowledge of android application development . So can you help me to develop the application so that i can control my appliances in my private network. That’s why i joined your course but controlling of esp32 using android application has not been included in your course. Plz help me to complete this project. Thank you again for reply.
Note: 1) Now, I am not using Internet. I am using router to just connect all the esp32 module.
2) In future, I will also add internet connection .

Hello, for that application I actually recommend the following:

  • Using a router (with or without Internet) where all your ESP are connected to. If you need more coverage, you can use a Wi-Fi wireless booster to expand the Wi-Fi range
  • I would recommend using a web server (instead of an Android application) to control your ESP devices

Rui
