Yes, I agree with you.

No, I don't need absolutely HTTP, but HTTP allows the end user to use a 
standard Web browser (and allow me to avoid writing an app for Android, 
iOS, ...).

First of all, many of these services aren't free. And I admit my 
ignorance around those topics. For example, is it possible to avoid 
writing an app for smartphone? I don't know.

Moreover, are the status of all my devices stored somewhere in the 
cloud? In this case, I should think of privacy, security, attacks from 
hackers... it's another job.

Thank you for your suggestions... I'll study a little more on MQTT and 
related scenarios
