new (clean) installation of OpenHAB
add a gateway to the android application
add sensors in the android application
I press +
here, too, I click
here, too, I click
automatically appear sensors, added in the application android
I did not enter the developer key, it is needed for the gateway itself, for example it is possible without it
well, then we add things, create a file of items as written in the first posts, now there is no time, if necessary, tomorrow I’ll finish it, but I think you do not even have to work here
