Nice!
Make sure to add your project to OpenHardware.io and tag it with "MySensors" and "Contest2016" :)

Nice! I will check my Samsung if I can do that!

In my "research" I found out that some Samsung TV's and other manufactors have a serial port that can be controlled like this.

very cool idea :thumbsup:

Now, that's cool.. I have thought about doing something similar, to detect if my tv (also an LG) is turned on. And use that to control some lightning in the living room. But as so many other things, it's only on the idea stage at the moment..

I'm currently doing that. When my TV turns on, the light behind my TV also turns on. But because I don't want to spam my TV with requests, there can be up to 30 seconds delay before Domoticz knows that the TV is on or not. But there is also a USB port behind my TV. I have noticed that there is only power in the USB when the TV is on. So I thinking of connecting the USB port to my Arduino to check if the power is on or not.

Sooo... after some waiting i recieved my RS232 to TTL... but soon found out that my Samsung does not use the RS232... but a 3.5mm stereo as a service port... seems like its the same protocoll so it should be able to do everything from changing channel to volyme, source and other cool stuff...
Build Plans:
A great weekend project... :) I will be back!

@sundberg84 Sounds like it would work! Looking forward too see the result! :smiley:

Im not having any luck with this project. I have made my Arduno->RS232 to TTL -> 3.5 plug and it seems to work when im testing. Connecting it to my Samsung does nothing. TV does not seem like its able to send any status... What i have read its possible to send command in hex to do different thing but at this point im pausing this project... I need a new TV as well so i might solve it with bying a LG ;)

@sundberg84 I'm not sure if any of the current LG TV's have an RS232 port anymore. Most new ones (at least the "smart" ones) are now running WebOS and can in theory be controlled through it over IP. I have two LG TV's, one is a 2010 and it has a serial port, but my 2012 Smart TV does not.

@sundberg84 That´s too bad! I thought it would work with the 3.5 mm plug.
It would be funny to see the salespersons reaction when you are in the store and asks after a TV with a RS232 port! -

Why not have the Arduino keep polling the TV to see if it's on, and then only when it is on, then send some signal to your controller (Domotics) that the TV just came on. Then Domotics could do whatever (turn on/off other lights, etc...)? Power (battery) is not a concern on this node, as it's powered by USB.

@TRS-80 For some reason, if i'm sending request too frequently the response from the TV get mixed up and unreadible. Sometimes it takes few seconds for the responses too arrive.
If I'm also changing volume or maybe channel via arduino and that is happening at the same time as arduino is checking power status, it will get som weird response. But this is only a problem when the TV is on, so you have point. I should be able to change the frequens when the power is off to maybe 5 seconds and keep 30 seconds when the power is on.

Perhaps further debugging and/or careful programming and error trapping between Arduino and TV could alleviate some of those problems? And/or, once TV is set to on, have Arduino check less frequently?
I still would prefer the former solution over the latter, to make it more nice, faster response, and higher WAF as well as "show off to friends" factor. I mean, let's get our priorities straight, that is at least partly why we do this, right? :)

It seems the link to the RS232 to TTL converter went stale. I am ordering this one instead: https://www.aliexpress.com/item/RS232-To-TTL-Converter-Module-COM-Serial-Board-MAX3232-MAX232CSE-Transfer-Chip-atmega16/1920204765.html?ws_ab_test=searchweb0_0,searchweb201602_2_10037_10077,searchweb201603_1&btsid=af8a76b1-c9b5-4ea7-9c5b-209cdc11d1f1

I am going to have to try this. I have a 60 inch Sharp Aquos TV that has a 9 pin serial port. I have ordered one of these: RS232 TTL converter It is a china version, but I couldn't beat it at $0.73 with free shipping. The other nice thing is that in the manual for my TV on page 51 it shows the complete serial protocol and command set. If I can in some way combine this with the IR sender and receiver project to control my cable box too, this would be a well rounded solution.

So I received my serial converter the other day and did some testing. I connected the converter to one of my FTDI adapters and to the TV. I found out how to send the commands to the TV. The TV will respond with OK if the command was successful or ERR if it wasn't. The one thing I can't get from the TV is feedback such as power on and other commands. It would be nice to be able to tell when it is turned on and off manually, but I will work with what I have.
