HI Darkg
Not sure if that can be done have you tried if so what was the problem , i have my roomie set up on a room by room so say living room. In this i have two lightwave rf sockets and one plug. So first i added the device which is lightwave wifi link this is done by manualy adding ip adr then using port 9760.
I then added an activity say lamps it opens remote which is lightwaverf i then add remote design i choose a new design then i choose add button now then the command for the plug its .DEVICE ON then Parameter 1 is the room Parameter2 is the device. you need to now how the rooms are set up on your lightwaverf setup so in my case when i open the lightwave rf app the first rooom is livingroom so i would put 1 in parameter 1 when i click on the lightwaverf app on livingroom it takes you to next screen this shows the devices you have set up in my case i have lamp and tv so if i wanted to switch the lamp on i would put 1 in parameter2 box or 2 if i wanted to switch the tv on.
Hope this makes sense is try it and see come back if you require help or submit a ticket to roomie support have found them to be very helpful
