I had an idea which I think might be cool if it could be done for pimatic users with kids or roommates. Of course you want to have the comfort to access almost anything but sometimes you might not want your roommate to play with your heater or switch your lights all the time. Same with kids (sometimes your roommates might act like they are). Is this feature implemented or at least a good idea? So you could like easily say only users of a certain group are allowed to switch devices in this room or something.
