Samsung Smart TV (on or off)
Posted: Monday 22 December 2014 15:40
Does anyone know, whether or not it is possible to detect if a Samsung Smart TV is turned on or off using the network connection?

Probably "YES". My TV (old one now) will not respond to a "ping" when it is in standby, but WILL respond when "on". You can use a script to ping the TV occasionally and to set the state of a dummy switch. This is described in a separate part of the wiki under "presence detection". The script is called something like "check_device_online.py". You would need to modify this for your TV's IP address (I assume it is static?) and to start a CRON job which runs this script every hour. I have this script running to ping a mobile phone.

Thnx for the reply.
I already use the ping script for some other devices so I am familiar with that. I also own an Onkio receiver and that has a very cool (linux) command line tool that can control almost any function and also query the power state. That's (in my opinion) a more intelligent approach than a ping so I was hoping to accomplish the same functionality with my Samsung TV's.

Maybe start with telling us the type of TV you have

Tested it, and it works on my Samsung TV that is connected to the internet.

Understood about the intelligent query - much better solution if available. My old (series 6) Samsung does not appear to expose a web-page or a command-line interface. I don't think (?) it has any SNMP functionality either, but that might be worth a check? This is outside my (current) expertise... One other thought: my TV is plugged into a Z-wave switched socket with a power metering function (to provide the ultimate "off" control!). I can easily see if the TV is on (about 70 Watts) or in standby (about 5 watts) using the switch data.

Haha Tony, you keep telling me stuff I already use 
I use a Plugwise circle to monitor the power usage and a LUA script to switch the LED lights (Fibaro RGBW z-wave controller) behind the TV on or off automatically based on the power usage. So all is working. Wel, most off the time anyway. Sometimes the powerusage is not returned. Probably has something to do with the range op my Plugwise network.
It's just that there are APP's for your Android and iPhone that can controle certain aspects of the TV. If an APP can do that, why not Domoticz. At least, that was my way of thinking.
Btw, I have a UE40H6200 and a UE55F8000

Keep us posted, it would be nice to see webcam in dual screen view when doorbel rings, or things like that

the samsung remote sourcecode posted here might help:
http://forum.samygo.tv/viewtopic.php?f=12&t=5794
there doesn't seem to be a license though
it worked very fine on my samsungtv, but I decided that I do not want my tv to be in the network and thererfore control it via harmonyhub instead.
maybe also worth to mention that several (all?) samsung tvs can't be turned on via wol, as the network has no power when the tv is turned off.

Hi,
I'm checking if my Samsung TV is on or off using ping.
Since I'm using a dummy light switch for this, I thought it would be nice to be able to turn the tv off by clicking on the switch icon.
I have a working python script that turns the tv off. Can I use this as an 'off action' for the switch?
I tried, but it doesn't work. The python scripts works fine from the command line. Are script actions logged somewhere?

What is the exact line you entered in the 'off action' field?
And can you share you script?

I presume that the Python file is executable for your pi user?
Have you tried this: "script:///home/pi/domoticz/scripts/samsung_tv_off.py"
I will try this script myself tonight.

I also made the mistake to change the TV type to my own, but somehow that broke the script.
I changed the line back to:
tvappstring = "iphone.UE55C8000.iapp.samsung"
and using your full path, fixed it.
I'll probably never use is, but now I can turn my tv off using Domiticz

Ok, I am an absolute beginner here. Can you guide us step by step exactly what we need to do to interface with the Samsung TV and execute the command please? Hopefully, when I understand how to do this properly, I can actually contribute back to the community.

You can find how to do that in the wiki: http://www.domoticz.com/wiki/Presence_detection
Second, use the python script in this topic (samsungremote.py), and substitute your tv IP address in the script.
Then, use the script as 'off' action for your TV switch:
