Hi

Use Arduino-JSON 5.0 library.

https://github.com/bblanchon/ArduinoJson/tree/5.x?files=1

It will fix issue.

Nuba123 commented 5 years ago

Hi @TrickSumo , Thanks for your reply. I installed ArduinoJson 5.13.1 and this issue is solved. But I got the error message in IDE serial monitor as-- "DHT11 Sensor Read Failed". Basically, I work with DHT11 sensor and ESP8266 to send the data to Google Firebase DB.

I set the baud rate in serial monitor 115200 same as in sketch Serial.begin(115200); I connected the DHT11 data pin (2) to ESP8266's D2 (GPIO 4). Following is the script.

Thanks so much for your reply. I tried according to your provided link “Code to interface NodeMCU ESP8266 with DHT11.”https://gist.github.com/TrickSumo/f1aecd17972aa3b6c0668750c3309714. And connect the DHT11 with ESP8266 after upload this program. Unfortunately, I got the same error message””DHT SENSOR READ FAILED. I also installed the specific DHT11-master library according to the following blog suggestions. https://arduino.stackexchange.com/questions/36765/arduino-uno-sensor-dht11-failed-to-read-from-dht-sensor. And installed the DHT11 library https://github.com/adidax/dht11. Following is my script.

Which makes sense to me that the sensor is not reading anything. Humidity 0.00% Temperature 0.00C Would you please help me to sort it out ? May I get your e-mail address/skype ID to discuss in more details. Can anyone please give me an idea to sort this problem?

Hi @TrickSumo, Thanks much for your effort. After your words I tried with DHT Tester example program using UNO board and 10K resistor. Unfortunately, I got several errors and didn’t fix it. And I wanna buy a new sensor. I found this sensor with two specified name “HALJIA 2PCs DHT11 Digital Temperature Humidity Sensor Module for Arduino” (amazon.co.uk) and the other one “ DHT11 Temperature and Relative Humidity Sensor Module NTC Thermal KY-015 Arduino” (ebay.co.uk). But I am not sure are they compatible with the ESP8266 module or not? Would you please take a look on it?

And secondly, I already install the NodeMCU board and checked its connectivity with the COM port using Examples->ESP8266-> BLINK before those issues occured. I set D7 in the first parameter of three functions in the BLINK example. I test with a LED and it was blinking in my case. It make sense that the board is properly installed with my PC. how do I test the ESP8266's connectivity with the internet? Would you mind to help me in this context?

TrickSumo commented 5 years ago

Hi @Nuba123

I am using DHT11 which is available on eBay.

Use this code to check connectivity to firebase.

It must upload any random value (equivalent to infinite) to firebase real-time database even without any temperature sensor.

To create real time database, you can refer:- https://tricksumo.com/use-firebase-with-mit-app-inventor/#How_to_use_firebase_with_MIT_app_inventor_2

Don't forget to update WIFI and firebase details.

Nuba123 commented 5 years ago

Hi @TrickSumo Thanks for your quick reply. To answering your previous question " Is DHT connected properly" ? As I understand from ESP PIN WorkOutSheet, Pin D1=GPIO5. I connected the DHT11 sensor's GND and VCC pin to ESP's GND, 3V3 properly. The data pin of DHT is get connected with ESP's D1. And I define in sketch #define DHT11PIN D1 and I tried in either way #define DHT11PIN 5. Is it okay?

Now, I am trying your code provided for Firebase test only.

TrickSumo commented 5 years ago

Hi @Nuba123

Pin connection seems Ok.

Hope you successfully connected nodemcu to firebase.

Nuba123 commented 5 years ago

Hi @TrickSumo I afraid I can't find the VV pin. In my MCU the first pin is D0...D4, 3V3, GND, D5 ...D8 Rx Tx GND 3V3 ( from top left) and the other way around listed as Vin GND RST EN 3v3 GND clk ....RSV A0 (BOTTOM LINE ). I guess in my case it might be Vin pin. Is it okay? Sorry, am unable to upload the Node image because I didn't create my own repository.

Nuba123 commented 5 years ago

Ignoring firebase Failed to read from DHT sensor! Ignoring it! Current humidity = nan% temperature = nanC**

It seems that, Firebase is begin perfectly only once with no reading of DHT sensor. After one loop done the Firebase begin is failed again. I tried even without DHT connection.

Would you please take a look to sort my problem?

TrickSumo commented 5 years ago

Hi

Syntax is Firebase.setInt("tag-here",variable-to-upload-here);

Example:- To store temperature in demo >> value, use:- Firebase.setFloat("/Demo/Value",t);

Alternatively, you can also use Firebase.setInt("/temp/data",t);

Hi @TrickSumo Thanks so much for your every quick response. It really helps me. Finally, the temperature and humidity value is showing in Firebase console under my own project. And the issue was with the FirebaseArduino Library. It needs to be updated every time.

Now I intend to send these data in any platform (App/web application) as a user notification. How can I do it using MIT Inventor App? Or any other idea to reach my goal? Please, give me a complete guidelines to work through.

I found some step-by-step guidelines to 'Get Started with Web/IoS/Android' in the below link. https://firebase.google.com/docs/?authuser=0

How do I find the MIT App Inventor in firebase console to create an app using credentials according to your provided guidelines ? https://tricksumo.com/use-firebase-with-mit-app-inventor/#close

Hi @TrickSumo Thanks so much for your complete guidelines.

Nuba123 commented 5 years ago

Hi @TrickSumo Once again I need to know, is there any perspective to read the DHT data and send it to the Firebase console as a real-time data and using an MIT App to control/monitor the data from my own handset.?

If I can see the DHT data in Firebase console under my own project, it means I can be able to see/monitor from anywhere in the world using the URL. Above mentioned is in my own project case (DHT-Firebase-App). Its just my personal interest to know the goal of this iteration. Please let me know.

TrickSumo commented 5 years ago

Actually my aim was just to show working of final project and then provide link to written tutorial. But your idea of firebase part is really nice! I will keep it in mind next time.

Thanks for valuable feedback :)

  • I am getting a confusion to import the project(.aia from my computer) here; according to your today's commentary guidelines. In my case what would be my project to import? Is that an Arduino code to work with the DHT-Firebase?

MIT app inventor file (.aia file) is attached at the end of step 2 of that instructable. No need to create new app, just download and import it.

https://cdn.instructables.com/ORIG/FVN/AU0I/JUWYCP03/FVNAU0IJUWYCP03.aia

Then open imported project >> edit FirebaseDB details.

  • And the project name is showing in Project Bucket in right pane. Is that okay?

In that instructable, I had mentioned to put S_HO_C_K in project bucket because i had used this in my arduino code:- t1 = Firebase.getString("/S_HO_C_K/mantemp").toInt();

You can put anything there, but don't forget to modify code as:- t1 = Firebase.getString("/myproject/mantemp").toInt();

  • I set the security rules as Test mode to completing the Firebase Setup instead of Lock Mode? Is that might occur any issue to work?

As long as you have secret key, you can always go with lock mode.

  • I am running windows 10. Is this will be occur any issue to completing the App development?

Not at all. App is being created on server of MIT. Hence you can use any OS.

If I can see the DHT data in Firebase console under my own project

Yes, you can view data, but creating app helps to control NodeMCU. But still its optional.

  1. Change real-time databse rules to => { "rules": { ".read": true, ".write": true } }

  2. Add tagname.json at the end of databse URL.

Example:- https://test.firebaseio.com/tagname.json or https://your-project-name.firebaseio.com/temperature.json or https://my-project-name-firebase.firebaseio.com/dht.json or https://example.firebaseio.com/data.json

And so on...

  1. To view all data, use:- https://test.firebaseio.com/.json
Nuba123 commented 5 years ago

Hi @TrickSumo Thanks so much for your patience. Now I am really kin on to developing an app using MIT for my Android phone using wi-fi. And I find your below tutorial is useful. First of all I need to convert my .ino file to .aia file. Secondly, (.aia to .apk). How do I do that?

https://tricksumo.com/use-firebase-with-mit-app-inventor/#What_Is_Google_Firebase_And_What_Is_Google_Firebase_Used_For Stay Bless

TrickSumo commented 5 years ago

Hello @Nuba123

No, you don't need to convert .ino file to anything. Just upload this file to your NodeMCU ESP8266 (after some necessary changes).

After that, download .aia file from instructable. Import it in mit app inventor. Now edit project to add your own real time database URL and its secret key.

Then hit build button to download .apk file.

That's it!

Just follow this Instructable step by step:- https://www.instructables.com/id/IOT-Based-Room-Temperature-Control/

And tutorial to create firebase real-time database:- https://tricksumo.com/use-firebase-with-mit-app-inventor/#How_to_use_firebase_with_MIT_app_inventor_2

Hope its clear now.

Thanks And Have Fun :)

Nuba123 commented 5 years ago

Hi @TrickSumo Thanks much for your feedback. But I want to do this in respect of my own .ino code (sends the DHT sensor data to Arduino IDE and Google Firebase ). Would you please guided me to convert the (.ino) to (*. aia)? After successfully import the .ino code to my computer using MIT is that .apk file will be auto generated as executable (after hit the build button on MIT).

Can I have to download the MIT Ai2 companion app in my android phone? which I find from the below link. http://appinventor.mit.edu/explore/ai2/setup-device-wifi.html ( Step 1: Download and install the MIT AI2 Companion App on your phone. which I find from the below link.)

TrickSumo commented 5 years ago

Hi @Nuba123

Actually I am not getting your point but still trying to explain. So if I am getting wrong please correct me ;)

MIT will automatically generate .apk file after hitting build button.

Just download this file and transfer it to any Android device. Install the app and run it.

No need to download MIT companion app.

Also .ino file can't be converted to .aia. Aia is format of app inventor raw file.

  1. Upload ino to NodeMCU ESP8266. Now it will update data to firebase.

  2. Create app which can read data from firebase, that is aia file.

So as you can see, ino and aia both are different things.

Nuba123 commented 5 years ago

hi @TrickSumo Thanks much for your guidance. Now I understand that .apk file is an executable file which will be working in Android O/S. on the other hand, .aia file is the own project format of MIT.

I already design an APP plus its Logic from Block and save the project as .apk file. But the problem is I design the APP in Screen 3 and used screen1 and 2 for app design practice. And I integrate Firebase with screen 3 and 1. As I understand whenever I build the .apk file its saved with all its working screen. Though whenever I hit build and select (save as .apk file) on that time screen 3 was open. Its really urgent to know.

Is that might occur an issue to get the Firebase data into my phone app? How do I delete a screen? And how do I undo the Firebase Integration from any screen?

TrickSumo commented 5 years ago

Hi @Nuba123

Hope you enjoyed your first app with MIT app inventor 2.

To remove any screen, there is option to remove screen somewhere in front of screen name.

To undo real time database integration, just delete dragged FirebaseDB from design window.

If there are three screens, first one will open in the app by default. To solve it, just add button on first screen which when hitted it redirect to third screen.

Also you can integrate same firebase with unlimited screens without any problem. So don't worry about it.

Are you creating this app for temperature sensor?

Thanks

Nuba123 commented 5 years ago

Hi @TrickSumo Thanks for your quick feedback. I resolve according to your guidelines but the first secreen is not deleted as it's a default screen. so, its a good idea to 'To Add a button on First screen and re-direct it to the 3rd screen'. I'll be very happy if you send me the 'logic ' to doing it. I am sending the DHT data to the Firebase using DHT11 sensor plus ESP8266 module.

Nuba123 commented 5 years ago

Hi @TrickSumo I resolve the redirecting issue in my app. Now the new issue is the Humidity and Temperature value is not showing in the App. I am following this tutorial and the app design is same like this. https://www.youtube.com/watch?v=3RPJtL2rnXc . And my logic is same like this tutorial logic as well. My phone, PC is in the same network.

What might be the issue

TrickSumo commented 5 years ago

Hi @Nuba123

Make sure that app is reading data from same path where dht11 is uploading data.

Example.

NodeMCU ESP8266 is uploading to '\temp\data'

Then app must read data from same path. So keep ProjectBucket of FirebaseDB 'temp' and read data from 'data' tag.

Now come to your case. According to that video data is being uploaded as:-

Firebase.setFloat ("Temp",t); Firebase.setFloat ("Humidity",h);

So make sure ProjectBucket option of FirebaseDB is empty and read data from respective tags. You can open firebase console to get more insights.

This may be issue. Except this, everything seems fine to me.

Nuba123 commented 5 years ago

Hey @TrickSumo Thanks much for your guidance. I already 'empty' my project bucket and set the data path in App logic same as in Arduino sketch. example Firebase.pushString("Humidity/Data",fireHumid ); Firebase.pushString("Temperature/Data",fireTemp); unfortunately, the issue is not solve . -I am using forward slash in the above parameter and simply copy Humidity/Data inside the App logic. Is that '/' might be an issue? shouldn't it. Though I checked without '/' as well.

Basically, My Firebase console is heavy loaded with sensor data. Suddenly it's stopped working and ask to'Recover Webpage'. And its difficult to check the recent sensor data. is there any way to delete this data? Or I can create a new project in Firebase and using new token+URL integrate with MIT. But this is not a shortcut idea I believe.

-what do you mean in this line, cant understand. 'Then app must read data from same path. So keep ProjectBucket of FirebaseDB 'temp' and read data from 'data' tag.

TrickSumo commented 5 years ago

Hello @Nuba123

It is not necessary to connect both device on same network.

You can delete firebase data just by pressing cross in front of tag name (you can search a video on that for more details).

For app not reading data, can't say anything. Everything seems fine to me!

hi @TrickSumo hope you're doing fine. Is there anyway to make an executable this part' collecting data (using dht) and sending data to firebase'? Basically, sometimes its asked to submit any executable file in submission. is it will be kind of saving the project in GitHub repository. please let me know.
