Quite simply, I’d like to write a smartapp that extends the existing “lights and switches” category. Essentially, I want to allow a light to turn OFF when another light turns on (and vice versa.) Sure, I could do this under another category, but it just makes better sense being a part of the existing “lights and switches” grouping… As well, it keeps common functionality together.
It would be odd if I go into “lights and switches” to turn a light on at sunset, or turn it off when someone comes home, but have to go to a COMPLETELY different part of the user interface (my apps, convenience or whatever) to have to turn on when another switch turns off.
Can it be done?
