The ESP Devices are most popular devices for IoT(Internet of Things). So having a realtime database is a challenge. In this video, you will see some most common mistakes done by the users. If you have any more errors, do not hesistate to mention it in the comment section. The entire video has the procedure to get started with firebase too.

Error List
1. Using the wrong version of the library (incompatibilty issue solved)
2. Connecting to WiFi (reboot / EN)
3. Entering wrong password for the authentication (App Password is to be generated from the google account.)
4. Editing the code without establishing the connection with the database
5. Email account (Use a new account for safety)

Great video! Downloaded your anonymous data logging sketch. Unfortunately after compiling and uploading I get this error "FAILED REASON: not found". What am I doing wrong?

Thank you for your excellent content.
It takes too long to verify the code or to upload it to the ESP32, is there a solution for this issue?

Hi there...!, I found this video very helpful and everything works fine and now the question is how to fetch or send the data to the firebase. Could you please help me to come over that?

Good video. I have an issue, if I want to set the sendDataPrevMillis below 4 seconds, the data fails and it didn't show in firebase. Any solution?

PLEASE help me.
After 60-120 seconds it stops to work and update data..
Like it's frozen
But in first seconds it works well, I did a simple Set bool in loop()
