Applications in WebOS 3.0 such as Netflix can be launched via IP control using the +DIAL APP LAUNCH command. You have to pass in a parameter name to tell it what app to launch.
Since there isn’t a list anywhere, I just guessed and was able to get Netflix to launch using the parameter “Netflix”.
So far I have been unable to guess the parameter names necessary to launch Amazon Video and VUDU, the other apps I’d like to be able to launch. I tried “Amazon”, “AmazonVideo” “Amazon Video”, “VUDU”, and “VUDU Movies”. No luck. Has anyone successfully figured out how to launch anything other than Netflix using the +DIAL APP LAUNCH command?
