To add a 2-wire (I2C) temperature or environmental sensor, you should select any pin, select the “Temperature (2-wire)” sensor type, and select a subtype (e.g., BMx280), specify the I2C address of the sensor as a decimal number. On the next row (Output2 in this example), you should define a I2C clock pin.
