Internet to Mesh Networking Home Automation Project using Blynk & Painlessmesh

[@AvinashRaiG]

Grate , what is the practicle real life application ?

[@techiesms]

In coming future where all the device in our home will be smart device and all of them needs internet connectivity. But on the same side our wifi routers have limitation of number of devices getting connected with them. So in those scenarios, mesh networking will be useful where only one device will be connected to the router and rest of all devices will be communicating locally with each other via mesh.

[@niteshpatel3334]

@@techiesms Will there be any interference between the ESP board WiFi and router WiFi ? Also can you please make some video where we can use RS Pi to make our own server using mosquito so that we don't have to rely on Blynk.

@@techiesms hi it's awesome ☺️ I want to create mesh network by using lora with esp32.. i want to send the lora data to server . In here i use one lora and one esp32 for one device likewise i have 4 device. So how can i create lora mesh network by using those 4 device ( in here i used the esp32 as a microcontroller) please help me

[@lelandclayton5462]

Basically it's a bastardized Z-Wave or Zigbee but uses WiFi. Would be better with out a cloud service in the way.

we are very thankful , for your good description, you survived our project!

[@abhijeetbyte]

Hi, how can we utilize two esp323 boards communicating wirelessly with mesh networking, and one of them sending data on Blynk app with the help of the internet? because in this video you are connecting one of the mesh networking board with an esp32 internet board via hardware serial connection.

[@elsh11]

Thanks a lot for sharing, I have a question, Can I use painlessmesh library to create a mesh network which has , multiple leaf nodes, and one gateway node, and connect the gateway to the internet , so that it can transfer data gathered from the leaf nodes to a server?

[@raagamparmar179]

NOT AGAIN! YOU READ MY MIND AGAIN!!!!! Awesome, man!!! Video quality is increasing by every video.....THIS IS JUST AWESOME!!!! Keep Going..... :-D

[@aazimhassan1723]

Great work bro. Want to ask if the same scenario could be built using esp8266, or nodemcu?

[@vikingzeppelin]

This is a great tutorial for constructing multiple gaming handhelds with local online multiplayer gaming tournament. You can manage a single, non-gaming esp32 handheld to manage the tournament, the lobbies, and maybe even streaming if you have enough power in the handheld and enough power in the internet bandwidth (prolly dual sim). The gaming handhelds can speak to each other independently, and share that data independently with the manager handheld.

[@chirots]

From Thailand, I love this project and idea. I have a request for upcoming video. Can you please do two more projects like this project; one for NRF24L01 and another one for LoRa?. They will be interesting projects for those who live in rural areas and in the farm.

Can you try to do esp32 mesh network and MQTT communication?, This is my request, I have tried to do esp32 mqtt communication with mesh network and mesh networking is working well but esp32 not able to connect mqtt server/broker, I don't know why esp32 not able connect to server, but it's working(esp32 mqtt communication only) without mesh network.

[@dhaneshprabhu72]

Loved this video. You are my guru in IoT and automation. Awesome concept and explanation. But why are we connecting first 2 esp32 boards serially? Can't we control both the 1st 2 esp32 boards from Blynk? Or was it done for the purpose of just demonstaration.

[@josephpatrickbjacob8787]

Nice!!! I just want to ask what if I replace the esp32 that is connected with another esp 32 and connected to the mesh with a esp01 it will still work? If yes, How?

[@patilmm123]

Can we connect this esp mesh with internet on same nodemcu and not using any serial nodemcu?... in above example there is separate nodemcu for blynk.. is there any solution to avoid it and use painless network and connect to wifi internet in the same code?? Any updated version right now? please respond if possible

[@soovui]

Bravo, fantastic and super clear explanation of all. Can't wait to see u could teach on how to do the dimming...and lora mesh network

[@hasanershad63]

Great video man. Is there a way to avoid blynk and use Lora for mesh? 3rd party limits the application of the idea.

Hi it's awesome ☺️ I want to create a lora mesh network by using ESP32? Can you give any suggestions to create it pls?

[@manuelseixas678]

That's nice!. Very nice. But how can I send the same code to all boards and decide among themselves which can use a internet connection? According to the proximity to WiFi they decide what will be the server.... Yes, this will surprise everyone! Any ideas to do that??

[@harivardhanreddy1094]

Hi, I am confused. @1:19, a serial connection between the middle one (name it B) and left one (name it A) is used? if so, it acts as a routing path (already designed) for the two modules (C and D) in the right. As far as I know, the mesh network should be configured automatically. In other words, in the beginning, all four modules do not if they could connect to wifi (or the internet). Then, 'A' finds that it can connect to the internet, others cannot. After a while, 'C' and 'D' recognize that they could access the internet via 'B'->'A'->Internet. How a ESP32 can perform this? Thanks
