This is an Eventghost plugin for IP-based Sony TV's, probably starting with 2013 or earlier and extending to at least 2023.
It is based on the plugin archived at https://github.com/dequi/eventghost-general-PluginDatabase/tree/master/Sony%20TV%20Network%20Remote%20Plugin/0.0.2
Changes made to the original IRCC-only plugin are:
1.) Fixed bug that didn't allow the IP address and pre-shared key to be set via the dialog box. The hardcoded defaults would always be used instead of those set in the user configuration dialog.
2.) Added Simple IP control event. No built-in presets; the command strings must be gotten from here: https://pro-bravia.sony.net/develop/integrate/ssip/command-definitions/index.html
3.) Added REST control event. No built-in presets; the "service" and "command" strings must be gotten from here: https://pro-bravia.sony.net/develop/integrate/rest-api/spec/index.html - Note that for a random reason, the REST control strings of "service" and "command" are all contained in a single, one-line command string. First comes the service name (like "audio" or "system"), then a space, and then the JSON REST command w/o any newlines.
