Use the already-done JS code to add H/J-series TVs
You've done amazing work on the plugin! However thousands of users with early-Tizen H/J series TVs are being left out.

Good news: now the JS code for H/J-series Samsung TV is ready - so it should be easy to take it and incorporate those TVs with your plugin.

(it works well, but is not updated for the new iOS 12.2 remote capabilities)
