Smartapp brain plus#So one button on the remote might turn off 2 overhead lights while another button turns off the 2 overhead lights plus a table lamp. And some standards do let an end device associate with more than one local group. This type of group is usually limited to a much smaller number of devices than a room.Īn end device, like a light, can sometimes only be directly associated with one controller, but a controller can associate each button with a different local group. From the network point of view, delegates message control (often with complications to status reporting.) From a person’s point of view, used to match a controller button with a group of nearby devices. Typically this is a handheld remote and an entertainment center or a wall switch and a group of lights. Allows a local controller to communicate directly to a few specific devices. These days, several protocols group rooms into zones, like “First Floor.” HomeKit does this. Some home automation controllers do behind the scenes stuff that allows groupcasting to a room. For the network, the group members are almost always line of sight to each other, which in turn makes possible some delegation to local controllers and some other traffic balancing. Useful for both the network itself and the people. Many home automation protocols often several different types of groups. Of course, this seems a little at odds with the SmartApps as connecting objects with UI focused on configuration rather than data presentation and control of state.
