In reply to Luis.

Thanks for your feedback.
We need to update our guides to be compatible with the latest version.

I appreciate all the work that you do, and have a few of your books, and thought to share the experience i had with this project.

to make a long story short i could not get it to compile with the latest ESP32 Cores or the latest Firebase ESP Client.

Only esp32 core version 2.07 worked and i left it at that: And that could be a plus\minus version.
Firebase ESP Client version 4.2.7 worked . The latest version to date 4.4.15 did not compile it_

I have great respect for your work, thank you and glad to share.

Ciao

Hi, thanks for this project. This was the project that got me interested in Firebase and the huge potential it has, and I’ve used Firebase a lot over the last year or two. The ‘Firebase-ESP-Client’ library has been deprecated though. Although it is still available, the author, mobizt, reports the library as having ‘unfixable issues’ and has created a new, very different library, ‘FirebaseClient’. Perhaps a similar tutorial using the new library would be something that would be something you would like to do. I and many others would benefit greatly from such a project.

Is it possible to use push buttons in conjunction with Firebase? If yes, how can it be done and are there any example projects available?

Hi Sara, I have a problem with the Firebase_ESP_Client library, today I updated the FirebaseESP32 library.

The problem is what the streamCallback(FirebaseStream) tells me “variable or field ‘streamCallback’ declared null
56 | void streamCallback (FirebaseStream data)”

It’s right?

I use the code on this page and update the call with the new library.

//#include
#include

Thanks for your future response for me.

What will happen if I simultaneously enter values for 12,13,14? Because I want to always get the values of each node.

Hello, thank you for your tutorial like always, I tried updating the gpio values whenever I press a physical button, the set() function in the esp32 code would erase every other values under the parent path unlike how the set() function in the javascript code would. I used some lines from here that was used to send sensor readings in order to send the button states
https://randomnerdtutorials.com/esp32-esp8266-firebase-gauges-charts/

FirebaseJson json;
String buttonPath = dbButtons(buttonPressed);
if(Firebase.ready() && localSwitch == true) {
json.set(buttonPath, String(1));
Serial.printf(“Set json… %s\n”, Firebase.RTDB.setJSON(&fbdo, listenerPath.c_str(), &json) ? “ok” : fbdo.errorReason().c_str());
}
this are the screenshots of what happens if used the webapp buttons vs the physical buttons.
