Bticino and openhab

i´m using a Raspberry Pi3 and want to connect to bticino my home web F453AV.
I already set the internal IP address of the F453AV gateway in the config file and use port 20000
The item is configured to use the binding of Btcino interface but no light will be switched.
Is it necessary to configure the user/password of the gateway and wenn yes, how to configure it?

I’m linking OpenHab with bTicino through the MH200N. To get it working I needed to enable the IP range setting on the MH200N.
I only added the IP address op the raspberry pi running openhab and that way all requests for that IP address do not require a password.
