Thank you @scalz! That did the trick. Finally I can debug the code with readable serial feedback.
Ok @AWI so the example code is probably in need for some adjustments. Its kinda hard for a beginner like myself to learn the basics if also the example code suffers from questionable functionality. Or perhaps the functionality is ok but the code by itself is not clear enough to educate the masses.
I'm still having trouble understanding whats really happening when using the sleep() call. In my newest revision I'm not passing any interrupt conditions other than a time variable but still its obvious that the sleep is interrupted by the interrupt defined in the setup section. And as such, perhaps also some timer functionality is running while in a MySensors sleep.
Perhaps the API description is in need for some additional clarification.
Note: I've also deleted the attach and detach calls from the loop() section as this is probably handled by the sleep function (or other hidden code).
Advantage of this sensor is fast and easy installing by the non qualified personal. The sensor is designed for large agriculture facility with many greenhouses where is needed to be controlled temperature and humidity, the atmospheric pressure is for control the motor of air inlet and outlet. With help of the sensor installed outside the greenhouse provide information about positive/negative pressure inside the greenhouse.
Finlay the software read accurate temp/humid value of the Si7021, and only atmospheric pressure of BMP180, the temperature sensor inside the BMP180 is used only by the sensor itself to provide accurate atmospheric pressure measurements.
The sensor can be used also for home automation, and drone applications where is needed correction of the UAV barometric sensor compared to the ground barometric sensor, also humidity measurement can help the pilot to calculate more accurate flying time.
Looks awesome. Might be fun to put it outside before your front door on 31th October. Still have a Halloween project on my ever growing bucketlist xd
Blynk is awesome for controlling Halloween projects.

Both need protection (internal or external) from excessive discharge (or excessive charge, and short circuits etc)
That is where our new library to check battery level goes in, we could dream to have an internal mysensor security check of a LiPo battery ! they do so in 'copters
I may pass on that. I'm not used to software glitches having quite so much potential impact, and I don't need to save every gram. But to each their own!
