nice, it helped me to figure out byte for control 
and all self state events + stabile event messages after command I assume dont have T4 Bus format here as IT4WiFi ātranslatesā in normal language ?
Im sorry, my english not so good, may be i understend som your questions wrong. Please ask me simply.
is there any reply events after command have been send in T4 command format ?
If i think right - IT4WiFi is a some like postamt office via wifi (apk) and t4. Whot doing with commands while they going from wifi and ssl to really t4 i dont know
yes, im shure
but format of t4 native commands not what i can see in reply from it4wifi
i think it4wifi work as some translator from bust4 to bytes sockets
i can send to you all reversed javas from apk by free. but im dont know how i can do it. its not public information, you understand me? legacy and all about it
check PM 
I just ordered an IT4Wifi and expect to be able to integrate it with OpenHAB. Once installed, Iāll see what is possible to do. If you can send me also the sources youāve got, Iāll be able to start studying it. Thanks.
FYI Iāve been able to make something running in Java. Iāve started the writing of a binding. It may take some weeks. Stay tuned.

Maybe you can share JAR file and we can test it?
The file is available in the addons market place.
Your IT4Wifi should be autodiscovered on the network via MDNS.
Once discovered, a user named āorg.openhab.binding.myniceā will be created on it. You will have to grant him permissions using the MyNice app.
Once done, your gate should be autodiscovered and youāre ready to go.
If testers are willing to help me draft the documentation, more than welcome, this is really my pain point.
Wait a bit before jumping on it, I have an issue with authentication process.

You can proceed with the version I just updated a few minutes ago - it should be fine now. At least, it works on my prod server.

Hi, Gaƫl.
I successfully discovered my IT4WIFI, created user, grant permissions on app. Now Device have status āOnlineā. But it have no any channels 
What now I should to do?
There are no channels held by the IT4Wifi bridge. Once created it āshouldā auto discover a thing corresponding to your gate (that holds channels).
Something like that :
If itās not the case, you can try adding it manually :

Yes, only swing currently as itās the only one I have 
If you switch the binding log level to trace you will have the detail of messages exchanged between the binding and the IT4Wifi, with this I could progress in enhancing the binding.

What kind of messages needed? In this message I shared log of messages between app and IT4WIFI: Nice Garage Door Binding request - #9 by morchee
Itās not what you need? In trace log I see only INFO and VERIFY messages from IT4WIFI, the same message you can find in log, that I shared.
Perfect, I think with the messages from this thread I can make it.
