Samsung Smartthings and Domoticz

[Trigun]

Hi Guys,

I have a new Samsung TV(QE55Q70R) which works with the Samsung smartthings app.
Nice solution but I already have a great system that has all my devices in it and works great, Domoticz

Can anyone tell me if there is a solution to connect my tv(perhaps via smartthings) to my Domoticz system?

I have searched the internet but all solutions seem te be outdated or not applicable to my tv.

many thanks in advance!

Hi,

Have you seen this: https://www.pakstech.com/blog/control-tv-node-red/

For Node Red, more than one node is available and with MQTT you can connect NR to Domoticz.

WOW!! this definitely looks promising!

What the end goal is, is to create a scene in Domotics called "Movie Time" therefore I need to be able to turn the TV on but also start the Plex app. or select the right source.

would this be a possibility with Node-red?

many thanks!

Can you turn your TV on with the SmartThings App? I have a 2 year old TV that only responds to SmartThings once you have turned it on with the remote.

Yes I can turn it on and off with the app

Hi,

@Trigun.

You can try to connect Node Red with Plex.
A node exists: https://flows.nodered.org/node/node-red-contrib-plex-ws

Ok, thnx! The intention was to actually launch the app from the tv.

but thnx anyway!

ok, I had a look at node red. I must say that I have no experience with nodered at all.
it does seem like a good solution when using MQTT but I have no idea where to start. even the internet tells me different things to do.

is there anyone experienced with nodered to help me on my way?

thnx!

The original is in Dutch but there is a Google translate button in the menu.

I'm using this library: https://github.com/PatrickSt1991/pysmartthings

It's a fork of the original: https://github.com/andrewsayre/pysmartthings

With that I made python script and connected it to a domoticz virtual switch.

My script turns on the TV if it's off, when it's on changes the source to HDMI2 to start my PS4.

You could use that library to do the same for you.

If you need any help let me know

Can you share some simple python examples here so we can learn from it?

Is mqtt only way to connect node-red and domoticz ?

No. You can also send HTTP Requests (GET and POST)

No. You can also send HTTP Requests (GET and POST)

Figured, but isnt this problematic with device states ? IE. you need to poll device states time to time to keep them synced in domoticz ?

Sure, sorry for the late reply.

Code: Select all

#!/usr/bin/env python2

        devices = await api.devices() // Calling all devices currently in your smartthins app.
	#print(devices)
        device = devices[0]  // device[0] is the device I need, in your case it can be anything.. just check print(devices)

        result = await device.switch_on() //Turn On TV
        assert result == True
        await device.status.refresh()  //Refresh TV, I'm not sure why I do this but it works
