Hi, Rui and Sara,,
nice tutorial you have here,, I already try this one: ESP32: Getting Started with Firebase (Realtime Database), and it works,, while writing this comment, I’m keep the ESP32 running and sent data to ESP32,, because I’m wondering how many counts it will store,, and I modify the delay time to 10 ms from that tutorial sketch (the original sketch you provide set the delay time 15 seconds),,

but for now, in this tutorial, I see you set the timerDelay to 3 minutes (180000 ms), it makes me wondering why we need to put that long,, will it affected something if I modify the timerDelay faster like below 1000 ms,,

Dear Sara
I have followed your tutorial and added the HX711 module to my project. However, I am facing some issues and I would like to save data to the database only when the weight exceeds 100 grams. Can you guide me on how to do this? Thank you.

Hello,

I’m trying to combine this code with the GPIO control code, but it doesn’t work when combining them.

I set different FirebaseJson for reading and writing and it didn’t work either.

The reading of the sensors works, but the control of the outputs does not work.

The terminal shows me:

stream timeout, resuming…

do you know what could be the error?

Thank you very much

Hello. Thank you for the work. What are the codes to be used in the rules section of the database?

In reply to Wolfgang Kübler. Hi. You can do it the same way you pass a string. Just make sure your json object is converted to a string before sending it. Or you can use the setJson function instead of setString. Regards, Sara

Dear Sara,

thank you, I will try it today.
To do the same, how would you code it using json functions?

Best regards
