thanks for this, working. great library.

Hi @spairo1741,

You can specify the I2C address in the constructor like underneath, where 0x76 is to be replaced with the desired address. The same goes for the bus; Wire can be replaced with another instance connected to other pins.

ForcedClimate climateSensor = ForcedClimate(Wire, 0x76);

One thing to note though, you're using Adafruit_BME280, not this library. Hence, the method above only works when using the library in this repository.

Kind regards,

Jochem

by default i2c is pins 21 and 22 in esp32.
I have to change them to the other SDA 3 GPIO and SCL GPIO 16 because I use esp32-cam there are no pins 21 and 22 led out.
that's the problem.

Hi @spairo1741

I understand. As I've said; Wire can be replaced with another instance connected to other pins. This can be done like underneath.

ForcedClimate climateSensor = ForcedClimate(Wire, 0x76, false); 	// At top
Wire.begin(SDA_PIN, SCL_PIN);		// In setup()

That functionality is part of the Wire library.

Kind regards,
