If you use the Philips HUE lamp, you would like to make a trigg which is being executed when, for example, your lamps turn on. Or turn off.
Unfortunately, this is not possible at the moment. The Philips HUE lights do nog have a mechanism to let us know which color they are, if they are turned on of if they are turned off or if they are blinking. If we do not know that, we can not carry out triggs.
Perhaps this will come in the future, but at this moment your HUE lights can not be used as a condition. This is the reason why they are not visible in the conditions, in the WHEN part of your trigg.
