Hello guys,

I've discovered, that there are 2 protocols to control this TV by Lan:

on 7676 port - upnp
on 52345 port - low-level samsung protocol


I've tried Gemote, ruSamsungTVcommunicator - both not working. I've found actions for Volume Up, Volume Down, Mute and few more which I can send from Device Spy and it works. I've tried to send various KeyCodes and got no success, unfortunately. The guy here had some issue in 2013, don't know if he found solution

So, I have few questions

1. Are there any win (or you can say even Linux) software which will work fine?
2. Can anyone say how could I say KeyCodes for remote control through upnp?
3. Is it possible to control tv somehow by USB, not Ethernet?


I appreciate your help guys, thanks

I too would like to add to your question - can anyone recommend an Android app that allows you to control the TV (turn off/on, change channel/volume) without the need for an IR port (over wifi)? I've looked around but most apps seem to be for older models.

Thanks Zoe, but I forgot to add one tiny insignificant requirement... It has to work on non-Samsung phones or on AOSP Samsung Phones (I have a S3 running an AOSP variant, the wife has a Nexus 5)...

Anything for the likes of me? Doesn't have to be anything fancy...

Did you try to download the APK then install it manually?

Yes - it won't install (incorrect format). As far as I know it requires samsung's touchwiz library which only works on their roms..,

I'll try some other apks but I don't hold much hope

Ok, I've been thinking about the problem and it seems the current alternate applications on the play store don't support h series. Bummer. The official samsung app promises an update in september, but I have no hope it will run on non-samsung phones/roms.

The fact that there are no apps to control h series can mean one of two things:
1. There is no interest from app develpers
2. The communication between app and tv is proprietary and encrypted.

I believe the second option is closer to the truth, but so far I haven't found any technical analysis of what goes on between app-tv.

So, let's analyse it!
I ran a simple nmap scan against the tv and found ports 8080, 8443 and 6001 open (amongst others). The first two seem to be http/https, the last one looks like X11 (though it's likely a false positive). @Devs, is there a thread discussing open ports on H series?

We should do a packet capture to see what traffic passes between the app and the tv. To do this, we need to be able to run the app (the OP's original request)- how about bluestacks?

It seems it's possible to run a S4 ROM in Bluestacks, so you could install the apk and (try to) communicate to the tv.

I'll try to set it up if I have time and do a packet capture and report back -- this unless somebody beats me to it

App even exists for Windows if you prefer to emulator

Oh, I had no idea - It looks less convoluted than bluestacks (since my main system is linux and I would need a VM anyway to run it). I'll give it a shot. The protocol should be the same.

Thanks a lot!

That's what I was going to say. I tested the windows app and seems to run OK and export most of the remote controls. Running a fiddler session to intercept the traffic seems to show some websockets activity, but I had no time to analyze it properly
There's a 3rd party android app with the same issue of limited H series support, I guess they are reverse engineering the protocol as well (I wonder if there?s an doc at Samsung smartv developer site?)
