The Beolink app works as a client for the MLGW. You have to set up your MLGW, assign it to your system with all link systems and Beo devices in your house. All needed sources and buttons will automatically appear on your Beolink app and you can control your system all over the house via wlan.
In addition MLGW supports home automation systems like Lutron, KNX, IHC....and RS232 controled devices like Lintronic.
You can create virtual buttons that activate macros like closing shades, turning on the light, power on your Beovison...with one button.
Or make a "Good night" button, that set your main Beovision to standby, shut down the lights in the living room and activates at the same time your ink Beovision in the bedroom and activates the bedroom lights.
If you have a Beo5/6 you can import the config. file directly to MLGW.
Maybe this will help (?)...
