Hi.
In this configuration the board is always on.
It needs to be to keep the web server running.

In reply to Sara Santos. excellent answer, that I wondered about. In this current version page the board is always on? is there a way to read the parameters that dos not consume as much power?

Hi.
Yes, you can add deep sleep to the web server code.
However, you won’t be able to access the web page while the board is sleeping.

Sara

I wonder on how to decrease power consumption by just updating the page every minute, is there a way to add deep sleep to the code?

Bonjour,
J’ai un souci de connexion, j’arrive à me connecter et voir la page web.
Mais lorsque je ne l’appelle que plus tard j’ai souvent: The request timed out et je peut ressayer plusieurs fois mais rien ni fait.
La seul solution que j’ai trouvé, c’est de débranché l’alimentation et la rebranché. La page web est a nouveau accessible.
Qu’elle peut être la raison?
Je tourne en rond!
Merci d’avance
Daniel

In reply to Pat. I modify library everytime it has been updated and it works fine. Did you update since you modify ?

Hi.
You may have a “fake BME280”, that in fact is a BMP280.

Hi Sara!
I have the same problem as Manu. Scanner says 0x76 address works. So I too modified the adafruit_BME280.h file as Manu did. Unfortunately this did not work for me. Still getting “Could not find a valid BME280 sensor, check wiring!” errors. Any suggestions?
Thanks!
Pat

Hi.
It seems you have a BMP280 and not a BME280.
The BMP280 sensor doesnt measure humidity.
