I am looking to control my Roku 3 from a home automation system and started by testing ECP commands from a browser on the LAN but am having mixed results:
Queries seem to work fine, e.g. http://<Roku IP address>:8060/query/apps
returns a list of applications.
However, a keypress command like http://<Roku IP address>:8060/keypress/home
returns an http 400 error.
Is there anything additional that needs to be enabled on the device for this to work? Any help would be appreciated.
