I have the old Sony "Video and TV SideView" app on my phone, which has gone through some feature changes and whatnot so I've been scared to update it for over a year now. I never used the content I think they removed, which was like a TV guide - all I ever use is the remote control features. It works, so I don't update it.

​

Anyway, it's the best android TV remote app I've ever used, but it'd be nice to be able to control the tv from my laptop, via some locally-hosted webapp or something. For instance, my Yamaha surround receiver hosts it's own webserver for simple control. It's not much, but it's something.

​

A webapp like this would also, in theory, be able to be controlled by, say, IFTTT or Google Assistant, if I were lucky. (My Sony XBR65x810c doesn't work well with google assistant as far as I know).

​

Whether it might run on my TV (may be asking too much) or on a computer in my house (the Sony phone app communicates via some sort of standardized xml protocol, by the looks of it), does anyone have any suggestions on the webapp front?
