Google Assistant - Samsung Smart TV Integration

Use your Google Home device as a remote for your Samsung Smart TV. There is no need for a Logitech Harmony device.

Requirements

Python 2.7
# pip install -r requirements.txt

Installation

CloudAMQP

Create a free account on CloudAMQP.
Create a new instance. The free plan is enough.
Go to the RabbitMQ Manager.
Add a new exchange:
- name: google.home.assistant
- type: direct
Add a new queue:
- name: samsung.smart.tv
- arguments: Message TTL with the value of 30000. The name of this feature is x-message-ttl
Go back to the exchange that you created and add a binding to the queue:
- name: samsung.smart.tv
- routing key: samsung.smart.tv

Locally

Check the config.ini file and add your own details there.
To enable to comunication with your TV you will need to put the correct IP on SamsungSmartTV.host. Your TV should be on the same network with the PC that will run this script. If you have an older TV (<2016) you will need to change the method and the port also. Check samsungctl for more information.
The CloudAMQP information also needs to be added. Make sure that you add the correct data there.
Run the script using python samsung-smart-tv-remote.py or ./samsung-smart-tv-remote.py

IFTTT

Create a new applet on IFTTT.
On this select Google Assistant and Say a simple phrase from there.
Add a phrase. Use only lower case letters (ex: change the channel on hbo).
On that select Maker Webhooks and Make a web request from there.
On URL add https://pspeaemf:ByOti2ToHWya_dV79B85GaDZaORBpi3L@lark.rmq.cloudamqp.com/api/exchanges/pspeaemf/google.home.assistant/publish. Change the username, password and the RabbitMQ host with your own.
Select POST method and application/json as content type.

On body add

 {
 	"properties":{
 	  "content-type":"application/json"
 	},
 	"routing_key":"samsung.smart.tv",
 	"payload":"{\"command\": \"CHANGE_CHANNEL\", \"value\": \"135\"}",
 	"payload_encoding":"string"
 }

In the above example, 135 is the channel number for HBO. You can add different applets like this for whatever channel you want and the only thing that you need to change is the the value node.
You can also use custom commands like turn off the tv, but you need to change the command node like in this example:

 {
 	"properties":{
 	  "content-type":"application/json"
 	},
 	"routing_key":"samsung.smart.tv",
 	"payload":"{\"command\": \"TURN_OFF\"}",
 	"payload_encoding":"string"
 }

Custom Commands

Here is the list of the custom commands implemented so far:

Command Code	Command Description
TURN_OFF	Turn off the TV

Make the script start at startup

If you use a Raspberry Pi to run this script you may want to make it start each time you boot your device. There are several ways how to do it. Here is one.

# nano /etc/rc.local

Before exit 0 put the below line. This will start the script 15 seconds after the device is up.

/bin/sleep 15 && cd /path/to/your/script && python samsung-smart-tv-remote.py &

# reboot
