Samsung Smart TV (on or off)

[pj-r]

Far as I know in the older models the network chip is unpowered while in standby so it cannot be turned on from network.

Has anyone used(or tried to use) HDMI-CEC to turn on samsung tv? I'm wondering if should I use IR-blaster or HDMI-CEC for that task.

I can confirm you cannot turn on a Samsung TV via network.
I don't know about your other solutions, I haven't tried.

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

The off action is:
script://domoticz/scripts/samsung_tv_off.py

The script is a slightly modified version of something I found on the internet:

sock.close()

Works!!!

I had to change KEY_TVPOWEROFF to KEY_POWEROFF

[pj-r]

There is also a command line client if someone would like to use it:
http://forum.samygo.tv/viewtopic.php?t=5794#p41376

I have it and it works nicely.

[d4nh]

Works!!!

indeed, nice find, had to change it as well. i dont think my presence detection is working very well, it turns off my tv everytime xD

Has anyone used(or tried to use) HDMI-CEC to turn on samsung tv? I'm wondering if should I use IR-blaster or HDMI-CEC for that task.

i'm using an RPi2 turned on via an SNMP script (PoE switch + TP-Link PoE splitter), CEC commands works flawlessly

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:
script:///home/pi/domoticz/scripts/samsung_tv_off.py

I have a quetion to this part of the script

Code: Select all

#IP Address of TV
tvip = "192.168.178.16"
#IP Address of TV
myip = "192.168.178.14"
#Used for the access control/validation, but not after that AFAIK
mymac = "b8-27-eb-f1-5a-f3"

tvip: TV IP abviouse
myip: IP of domoticz server?
mymac: MAC of domoticz server?
thanks

Yes, that is correct.

[thecosmicgate]

Is there anybody who got this working on a Samsung UE65HU7500 ?

I tried this pyhton scipt but getting : returned: 32512 everytime

[thecosmicgate]

Is there nobody who also try to run this on the hu7500 series ?

[thecosmicgate]

Still nobody ?
It would be very handy , but if it isn't possible then I had to think about something else to shutdown this TV using domoticz

[mvzut]

As an alternative solution: If you can spare the money, I can highly recommend a Logitech Harmony remote. The hub can be connected to Domoticz, so that you will always know in which state your TV is, and you can also switch it off and even on.

[proohu01]

I used the Domoticz build-in "System Alive Checker (Ping)" to determine if my Samsung TV's are on or off. However, last week my EU40H6200 got a firmware update. Since then, it always replies to a ping. Even when the TV is turned off.

I did an nmap to check for ports that might be used to find a new way of getting the power state of this TV. These ports seem to be open:

ports

samsung ports.JPG (29.09 KiB) Viewed 24895 times

So I don't want to control the TV. I just want to be able to determine the power state without having to buy a power plug with energy usage reporting capabilities. Is there a simple way? I am not a programmer but could this node.js express framework (port 8001) be of any use?

[juankar]

It doesn't wor with UE48H6500 (api ver 2.0) model of 2014.
Ah! it has not 55000 port open, it has 15500, but it doesn't obey commands...

Steps I took:
I copied your script to the scripts folder on my Raspberry Pi;
I changed tvip to the ip address of my Samsung smart TV;
I changed myip to the ip address of my Raspberry Pi;
I changed mymac to the mac address of my Raspberry Pi;
I changed tvappstring to iphone.UE40F6600.iapp.samsung;
I created a virtual switch with the script:// line in the off action.

It doesn't work, my domoticz log doesn't show any errors and my TV doesn't ask for permission or responds to the command sent from the script.

[Treve]

I use a simpler way to achieve this.

i own a Samsung UE40H6620SV SmartTV and detect by Network if the Samsung is on or of. It also works when Samsung is in standby mode.
I use this to prevent the lights go off when i watch late television, it works perfect.

1 - i installed new hardware type "System Alive Checker" (ping)

2 - I'm attaching the IP Address of the Samsung to "settings"

3 - Result is a virtual switch



When i try to add images as an example, i get the message "Sorry, the board attachment quota has been reached".

[nigels0]

Newer Samsung TVs ( >2014) have a different protocol and the 55000 port is not available any more.

[bigpea]

Hi all,
i'm trying to use this script, but I have one question, for my curiousity:.
What does it mean the string:

Code: Select all

tvappstring = "iphone.UE46ES8000.iapp.samsung"

I tknow that the UE46ES8000 is the model of the TV, "samsung" is the brand (iphone and iapp I don't know), but in practice what they do?

Thanks.

[trixwood]

it is used in authentication with the tv.
Change it to something else and you will see a popup on your tv, asking if you want to add this new remote.
And you have to accept it on the tv...
