Prototype stage, there are two versions being tested.
And version 3.0 is quite postponed due to the high cost of components.
Added after 45 [minutes]:
In June, a new version of the software should appear, it will have a lot of news and improvements that have not been available so far.
Traditionally, the application will show more than is needed for the inquisitive :)
Perhaps there will be a digital signature of the application, so far I am collecting capital for its purchase, and it turns out that these are not cheap things.
In the era of all ransomware and other threats, such a signature seems to be mandatory in the application.
I am also waiting for suggestions on what is missing in the application, perhaps it will be included in the June edition.
