ifttt for google assistant with " Say a phrase with a text ingredient" ?
repeat the call for each camera, and pass the tv as the variable?

The ifttt suggestion would work and also an dialogflow solution which is probably the most difficult/advanced approach. Dialogflow is intended to for chatbot like solutions.
So I want to say thanks everyone for your help. After looking into IFTTT I have realised that this will do exactly what I need.
As walaj suggested, I can setup one IFTTT for each camera and pass the chromecast as the variable. Unfortunately, I am having trouble getting the variable. Hopefully someone can help with where I am going wrong!
To trigger I say: show me the driveway camera on the $ TV
where $ is the variable like ‘kitchen’. (Something weird that happened is for some reason $ is being stored as ‘the kitchen’ despite the word ‘the’ already being outside of the variable. When it confirms this back to me it says ‘OK, casting now to the the kitchen TV’. Note the second ‘the’. Not a big deal as I can have HA look for the variable equally ‘the kitchen’. Just a weird one).
My IFTTT body looks like this: { “action”: “call_service”, “ifttt”: {{TextField}} }
Then I have a HA automation which looks like this:
- alias: chromecast_camera_driveway
trigger:
platform: event
event_type: ifttt_webhook_received
event_data:
action: call_service
action:
- service: notify.craig_phone
data:
message: "Chromecast = {{ ifttt }}"
I was originally trying to get the camera to cast in the code but then in trying to debug I changed it to notify me of the variable. All I ever get is in the notification is 'Chromecast = ’ and the variable is blank. I have tried using variations of:
message: "Chromecast = {{ifttt}}"
message: "Chromecast = ifttt"
I feel like I am missing something really obvious! Whatever I do I can’t get the variable in HA but IFTTT has ‘the kitchen’.
Any help is appreciated! Many thanks.
Quick response - looking at my webhocks (I’m just using straight API web calls rather than ifttt_webhook_received events), but try changing the IFTTT body to
{ “action”: “call_service”, “ifttt”: "{{TextField}}" }
(put the textfield in " )
I had tried that but I have just tried it again but it makes no change for me. I still get the 'chromecast = ’ with a blank variable. Can you confirm if I am calling it in HA in the correct way? i.e. message: “Chromecast = {{ifttt}}”
Cheers.
I’ve just looked at https://www.home-assistant.io/components/ifttt/
try changing your message to:
message: '{{ trigger.event.data.textfield }}'
(guessing here)
Ha, you are right! I don’t believe it. I tried loads of variations including using ‘textfield’ but I must have had quotes around it or something. I can now get the message to consistently work to my phone so HA is getting the variable. Thanks for your help! Even though this works I still can’t get the chromecast template to work. This is what I currently have:
- service: notify.craig_phone
data_template:
message: '{{ trigger.event.data.textfield }}'
- service: media_player.play_media
data_template:
entity_id: >
{% if ( '{{trigger.event.data.textfield }}' == "the bedroom") %}
media_player.bedroom_tv
{% elif ( '{{trigger.event.data.textfield }}' == "the kitchen") %}
media_player.kitchen_tv
{% endif %}
media_content_id: https://URL:PORT/mjpg/cam-driveway/?user=USER&pw=PASSWORD
media_content_type: 'image/jpg'
When I trigger the automation my pushover notification shows the variable as ‘the kitchen’ so that must mean that ‘{{ trigger.event.data.textfield }}’ works but this doesn’t seem to work when inserted into the casting script. Here is what shows in the log:

As you can see it says invalid entity id for dictionary value so it is as though this bit isn’t matching:
{% elif ( ‘{{trigger.event.data.textfield }}’ == “the kitchen”) %}
Any ideas? Any help is appreciated! Thanks.
Craig
try changing the "the bedroom" to 'the bedroom' - I’m not convinced the " and ’ are the same
next step is to change ( '{{trigger.event.data.textfield }}' to trigger.event.data.textfield
Can’t believe I missed that URL, I doubled checked the log excerpt but completely missed the obviously URL in my code. It has been redacted now and password changed. Thanks for the heads up.
Also, you are 2 for 2 on the syntax front. Again, I’m not sure how I didn’t try this variation but you are bang on with this: trigger.event.data.textfield. I really thought it would need the {} to be considered a variable but I’m happy it is working! When I had it working I tried both the single and double quotes and both worked fine. Thanks for your help.
The last issue I have is being able to call different automatons depending on the IFTTT triggered. I was planning on having one IFTTT applet for each camera. So far I have one applet which works now but that triggers one automation which has a single camera URL within it. I need a way to trigger different automations. I think there should be some text I can add to the body to pass another variable that is hardcoded into the IFTTT Body. Something like this:
{ “action”: “call_service”, “camera”: “driveway”, “textfield”: “{{TextField}}” }
But I am not sure how to use this ‘camera’ in home assistant. It looks like this guy here has tried to do something similar using a ‘webhook_id’ but his example is using an event of webhook rather than an event of ifttt_webhook_received,
Any other ideas to crack this?
Many thanks.
ok - looking at https://www.home-assistant.io/components/ifttt/
suggests you can use trigger.event.data.camera to pull the camera value out
so try this:
- service: media_player.play_media
data_template:
entity_id: >
{% if trigger.event.data.textfield == "the bedroom") %}
media_player.bedroom_tv
{% elif trigger.event.data.textfield == "the kitchen") %}
media_player.kitchen_tv
{% endif %}
media_content_id: >
{% if trigger.event.data.camera == 'cam1' %}
https://URL:PORT/mjpg/cam-cam1/?user=USER&pw=PASSWORD
{% elif trigger.event.data.camera == 'cam2' %}
https://URL:PORT/mjpg/cam-cam2/?user=USER&pw=PASSWORD
{% endif %}
media_content_type: 'image/jpg'You have nailed it 
I didn’t think about having one automation for all cameras and passing the camera variable. I was thinking I would need one automation per camera. Thanks so much for your help dude, really appreciate it.
For anyone else that tries to implement this, here is my finalised IFTTT applet which I duplicated for each one of my cameras only changing the camera name in the trigger and the also in the Body:
Here is my automation which takes the camera variable for the media_content_id and the spoken variable (textfield) for the entity_id:
- alias: chromecast_camera
trigger:
platform: event
event_type: ifttt_webhook_received
event_data:
action: call_service
action:
# Used for testing to see what the textfield variable is on my phone when the automation is triggered
# - service: notify.craig_phone
# data_template:
# message: '{{ trigger.event.data.textfield }}'
- service: media_player.play_media
data_template:
entity_id: >
{% if (trigger.event.data.textfield == 'the bedroom') %}
media_player.bedroom_tv
{% elif (trigger.event.data.textfield == 'the family room') %}
media_player.family_room_tv
{% elif (trigger.event.data.textfield == 'the kitchen') %}
media_player.kitchen_tv
{% elif (trigger.event.data.textfield == 'the living room') %}
media_player.living_room_tv
{% endif %}
media_content_id: >
{% if trigger.event.data.camera == 'cam-driveway' %}
https://URL:PORT/mjpg/cam-driveway/?user=USER&pw=PW
{% elif trigger.event.data.camera == 'cam-garage' %}
https://URL:PORT/mjpg/cam-garage/?user=USER&pw=PW
{% elif trigger.event.data.camera == 'cam-pippa' %}
https://URL:PORT/mjpg/cam-pippa/?user=USER&pw=PW
{% elif trigger.event.data.camera == 'cam-sadie' %}
https://URL:PORT/mjpg/cam-sadie/?user=USER&pw=PW
{% endif %}
media_content_type: 'image/jpg'
I can now successfully say 'Hey Google, show me the driveway camera on the Living room TV and it will cast
Good luck to anyone else implementing

not bad considering i was guessing 
Pleased its working for you! Now to investigate if I can get my dafang camera to do something similar.
A year later… Is still ifttt the only solution for arguments? I use it too, but want an alternative, since ifttt is limited in Google assistant languages
Thank you very much @walaj and @dwarfer16 - for detailing this in such a great way that we can all benefit.
If you were to do this today, would you still use the same methods?
Hi MattP
I have to say that this solution is still going strong for me. I still use this regularly to view cameras on different TVs. I guess idelly I would prefer a not using IFTTT just to limit the number of systems that this is dependent on but I never found a solution. This still does the job

I’m trying to do something similar. I want a command to change the channel on my TV.
With google home and hassio I already turn on thelevision and change channel but with an “hardcoded” channel in the script
Now i want a vocal command like “Hey google, change the channel on 5”…
With ifft i already write a webhooks.
The trigger is working…
if in automation i write something like this
- id: '1580408252907'
alias: Cambia Canale
description: Cambia il canale della televisione
trigger:
- event_data:
action: call_service
event_type: ifttt_webhook_received
platform: event
condition: []
action:
- data:
message: "ciao"
service: notify.televisione
i see the message “ciao” in the television every time i say “hey google, metti canale #” where # is a number
but if i write
- id: '1580408252907'
alias: Cambia Canale
description: Cambia il canale della televisione
trigger:
- event_data:
action: call_service
event_type: ifttt_webhook_received
platform: event
condition: []
action:
- data:
message: '{{ trigger.event.data.canale }}'
service: notify.televisione
i see nothing on the tv… so i can’t “read” the variable that i say to google. Why?
This is the webhook body
{ "action": "call_service", "service": "media_player.play_media", "canale": "{{NumberField}}" }
there is no suggestions for this problem?
There is nothing obviously wrong with the webhook body or code - I would suggest changing the message to include all the fields, and using a textual notifier (email for example) so that you can test what is going on.
Time passes. I’d like not to use IFTTT. Is there any other way to process commands from Google Home nowadays?
Yeah, looking for a way too without ifttt’, anyone did it?
