Temperature and pressure should be displayed in the cloud.
Sketch is uploaded, but dashboard always shows 0. Both values are displayed correctly in the serial monitor. What am I doing wrong?

Hi!
The first thing that I would try is to remove the delay() from the loop(). That can interfere with the ArduinoCloud.update(). Using blocking delays inside the loop() should always be avoided when using the ArduinoIoTCloud library.
If what you want is to read the sensor every 2 seconds, you can use this alternative code:
Declare the following global variables:
unsigned long previousMillis = 0; // variable to store the previous time
const long interval = 2000; // interval at which to run the command (milliseconds)
and include this code in the loop()
// put your main code here, to run repeatedly:
unsigned long currentMillis = millis(); // get the current time
if (currentMillis - previousMillis >= interval) { // if the interval has passed
previousMillis = currentMillis; // reset the previous time
// put your commands to read the sensor here:
// ...
}
