In the coding it took me some time to realize that I initially misplaced one or two semicolons in wrong places. In coding with a for loop in an if command, it is really helpful to use indent and always checking by clicking on braces to see its boundary.
Another take away is that the library may not suit into every device so test and check it before. Trying out with examples in the library is always helpful.
The way of configuring pins in the piettetech_DHT library is also pretty amazing. It let me know that GPIO pins could also serve as a VCC or GND to power the sensors.
