Get motion sensor to fire rule once until its been reset to play video

Setup, Configuration and Use Beginners
1

So I have a motion sensor in the hallway which triggers my hallway light, which works fine. During the summer I rent my flat out occasionally, so then I would like to know when my guest arrive. So the idea is to use my motion rule:

rule "Update hallway light when motion happens"
when
    Item HueMotionBathroom changed from CLOSED to OPEN 
then
	Presence_Home.sendCommand(ON)
	Light_Hallway_Timer.sendCommand(ON)
	if (Light_Hallway.state ==OFF) {
		Light_Hallway.sendCommand(ON)		
	}
	
end

Which then will trigger this rule only once! (Until I manually reset it). Maybe a bit overload to check evrytime Presence_home changes to see state of Presence_WaitingForGuest, maybe move it to the rule above instead?

rule "Sensor update"
when
    Item Presence_Home received update
then
    Presence_Home_LastUpdate.postUpdate( new DateTimeType() )
         if ( Presence_WaitingForGuest.state ==OFF) {
		Presence_WaitingForGuest.sendCommand(ON)		
	} 
end

And finally to my problem, how do I play a local file from RPI on chromecast?

rule "Guest Arrived"
when
    Item Presence_WaitingForGuest CHANGED FROM OFF TO ON
then
  // Send email to myself...
  // Play notification on stereo, to make guest move to sofa
//Wait a minute or so
// Play video on chromecast from local file on rpi
end

NO, that’s the right way to do it or your could put your two rules into one:

rule "Update hallway light when motion happens"
when
    Item HueMotionBathroom changed from CLOSED to OPEN 
then
    Presence_Home.sendCommand(ON)
    Light_Hallway_Timer.sendCommand(ON)
    if (Light_Hallway.state ==OFF) {
        Light_Hallway.sendCommand(ON)		
    }
    if (Presence_Home.state == OFF) {
        Presence_Home.sendCommand(ON)
        Presence_Home_LastUpdate.postUpdate( new DateTimeType() )
            if ( Presence_WaitingForGuest.state ==OFF) {
            Presence_WaitingForGuest.sendCommand(ON)		
        }
    }
end

For your second question:
Your need the chromecast binding
A video file (mp4) that you put into the /conf/html folder
and link an item to the playuri channel
and send a command to the item with the location of the file :“/etc/openhab2/conf/html/welcome.mp4”

Thanks! Will try it tonight

So I can control volume on chromecast, but I can not show the video, just an empty cast symbol on screen:

Chromecast_LivingRoom_Playuri.sendCommand('/etc/openhab2/conf/html/test.mp4')
Chromecast_LivingRoom_Playuri.sendCommand('https://www.youtube.com/watch?v=8W4FP8ZD06I&t=24s')

Not sure what i am missing…

Maybe use " instead of ’

6

Tried both… without succsess

7

Is it user right issues? I am not very familiar with linux. The chromecast is on 2.4ghz wifi where the rpi is on the ethernet.

8

No it shouldn’t matter, it works for me.

9

So you can confirm that it works with youtube url? Can you show me your item and things definition, thanks for the help

I did it through the PaperUI
And created an item through the paperUI too.
When I send a command to the item it plays on the TV

11

@vzorglub did you set:
callbackUrl text optional Callback URL - url to use for playing notification sounds, e.g. http://192.168.0.2:8080

Is the Ip address, the IP of chromecast or openhabian? The documention is unclear on this point.

12

NO I didn’t set it. The binding finds the chromecast on auto discovery but then I only have one chromecast.
It would be the chromecast IP

I still can not figure out why it is not working:

2018-08-28 00:20:53.057 [vent.ItemStateChangedEvent] - Chromecast_LivingRoom_Playuri changed from //etc/openHAB-conf/html/test.mp4 to /etc/openHAB-conf/html/test.mp4

2018-08-28 00:20:55.137 [hingStatusInfoChangedEvent] - 'chromecast:chromecast:chromecast_livingRoom' changed from ONLINE to OFFLINE (COMMUNICATION_ERROR): Unable to load media

Is this some kind of permission problem?

My commands are:

    Chromecast_LivingRoom_Playuri.sendCommand("/etc/openHAB-conf/html/test.mp4")
    
    Chromecast_LivingRoom_Playuri.sendCommand("https://www.youtube.com/watch?v=8W4FP8ZD06I&t=24s")

Why is it called playuri and not playurl? And what is valid commands?
playStream("chromecast:chromecast:Chromecast_LivingRoom","http://st01.dlf.de/dlf/01/128/mp3/stream.mp3") does not work either, and I assume this is only for chromecast audio… However I can not confirm this and its not mentioned in the binding information.

14

/etc/openhab2/html/test.mp4
That would my path

15

Its still not able to load the media, i think it most be some be some permission errors. Can you confirm that you uses openhabian on rpi? Did you get youtube to work aswell?

16

I don’t use openHABbian on pi.
I use a standard installation on a linux box (Ubuntu)
YouTube works too.
I don’t know why your set-up doesn’t work, sorry

17

Thanks for your effort though, I suspect the openhabian user doesn’t have the right permission to cast. Because I can see the video if I double click on it on the samba share. So has anyone out here been able to cast video on an openhabian setup?
