I am glad to help you out 😋

[@praveenbhandari6901]

what all changes are required if we have to create a application for controlling more than one device

[@TechnicalYarana]

Bro how to use toggle button using this project please help me

[@creamyjade7547]

Thank you for your awesome tutorial. It's all been well explained and easy to understand. I just have a little question. How can I use multiple NodeMCU to the Firebase? How do I control a NodeMCU while not controlling the other NodeMCUs that are also connected to my Firebase database?

[@bytive]

i m really glad to hear it, for connecting multiple nodemcu connect all of them with Firebase database and then assign some variables to each nodemcu like : Node1: Node2: and perform operations on them

[@creamyjade7547]

Thank you very much for quick response! I'm amazed. I'll try to add variables and will let you know if it works!

[@MrHsynoruc]

what is the way of with only one button one click "on" then 1 second delay after '"off"

[@samsudinsamsudin7373]

im error : Error compiling for board NodeMCU 1.0 (ESP-12E Module).

[@fearlesss365]

does status keep's updating while turning led (on/off) in firebase realtime database??

[@bytive]

Yes

[@msmadaram]

have you ever work on android broker such as moquette or something like that ? when we have one esp8266 and we want to connet to it with 20 mobile phone what happen? each esp8266 or esp 12e can just have 8 TCP/ UDP connection what's your idea if we have 20 mobile phones and simultaneous they want to connect to one esp publisher? if we run an android broker on one of mobile phones and other connect to it we can connect to esp by one TCP/UDP from broker to esp, is it true? have you ever work on android broker such as moquette or something like that ? and we don't have any cloud on the net!!!!

[@bytive]

No i haven't worked on any android broker

[@christianbautista9010]

[@hraday_sadrani]

[@pv6043]

Sir this app is not working in the mobile phone.Can you suggest me what are the changes that i should do???

[@pv6043]

Sir answer? ?

[@W-ibrahim_Basha]

This happened for me at the beginning and this's what I did to fix it First of all, make sure you include the correct link of your database within your app with "/" and "https" for example Firebase("##########.firebaseio.com/"); 2. instead of this part of the code "On create" // Write a message to the database FirebaseDatabase database = FirebaseDatabase.getInstance(); DatabaseReference myRef = database.getReference("LED Status"); myRef.setValue(1); try this down below on.setOnClickListener(new View.OnClickListener() { @Override public void OnClick(View view) { Firebase mRefChild = mRef.child("LED Status"); mRefChild.setValue(1); } // to turn the LED on hope this would help

[@zainuddineffendieffendi7317]

if u did all the tutorial u will get it

[@W-ibrahim_Basha]

Hello again! Sir :) I have a question plz. If I'd like to use characters in the Ardunio IDE code to control the LED instead of ( 0 & 1 ) How could I do that?

[@bytive]

Hey sorry for late reply and check out Arduino code in this blog here i m dealing with strings : www.hackanons.com/2018/07/iot-with-firebase-home-automation-light.html?m=1

[@bytive]

bro i have tried it ,firebase is working fine with nodemcu

[@W-ibrahim_Basha]

I had similar problem. Here's the solution after you add (firebase-arduino library)! you can go to this link github.com/FirebaseExtended/firebase-arduino and down there go to "Dependencies" and download (ArduinoJson library).zip and add it to your Arduino IDE. upload your code again. and it will work

[@debapriya5957]

Nvm i solved it by updating and adding the firebase core 😂

[@bytive]

That's great

[@mrone3287]
