Community Hass.io Add-on: Google Assistant Webserver (broadcast messages without interrupting music)

Klagio · April 17, 2019, 1:30pm

Hi, since some days the broadcast is not working: when I put this URL in browser

http://192.168.1.10:5000/broadcast_message?message=Hello

I receive

{"status": "OK"}

but nothing is spoken

I added your repositary to hassio and installed the addon, my google_assistant.json is in the /share folder, I opened the addon GUI and it asks me to enter the authorisation code which I have done but then I get the following errors

‘’‘Traceback (most recent call last):
File “/usr/local/lib/python3.5/dist-packages/cherrypy/_cprequest.py”, line 627, in respond

‘’’

and then after that the gui doesn’t open as if it’s not running.

Any idea’s what I have done wrong?

I tried to add some info to the install/configure docs at https://github.com/AndBobsYourUncle/hassio-addons/pull/14/files/1014e4e4c00d3147e670914c003311eb954d5c40

Hope this helps. Not sure how to get my suggestions approved and added to the documentation, but I was able to get mine installed and working.

Same thing here…

Klagio · May 17, 2019, 10:18am

IS there anyone for which this addon is working?

bastienh · May 17, 2019, 10:35am

Yes everything is ok today. I think it was not working because of the “night mode” of my GH

walaj · May 19, 2019, 6:34am

works for me. virtenv on ubuntu

Klagio · May 19, 2019, 8:03am

Ok mine works now when I put this in a browser
http://192.168.1.10:5000/broadcast_message?message=Hello

but notify.google_assistant is not working anymore. Any clue?

action:
      - service: notify.google_assistant
        data_template:
          message: 'Alarm is armed'

notify:
  - name: Google Assistant
    platform: rest
    resource: http://192.168.1.10:5000/broadcast_message

walaj · May 20, 2019, 2:23am

Assuming the webserver is runing on the same server as HA, try changing the IP address to localhost:

- name: Google Assistant
  platform: rest
  resource: http://localhost:5000/broadcast_message

This works for me.

iamgrog68 · May 20, 2019, 9:18pm

I can use the notify.google_assistant service and I can send a broadcast via the web url on port 5000 but the web gui wont work.

Using Hassio on a pi3

bastienh · May 22, 2019, 12:20pm

I have 2 GH at home, is it possible to broadcast one specific GH ? thanks !

apop · May 22, 2019, 1:50pm

You should be able to just use the tts component for that:

bastienh · May 22, 2019, 1:54pm

yeah thanks, I know this component, but I do not like the way it speak, it’s not smooth as the original GH

apop · May 22, 2019, 2:44pm

Got it. Unfortunately I think that’s your only option, as you cannot target a broadcast to a specific device.

claytonjn · May 22, 2019, 2:47pm

The only way I know of to accomplish this would be to put the one you don’t want to broadcast to in Do Not Disturb mode. You could do this dynamically but it gets quite complicated with the more assistant devices in your setup.

bastienh · May 22, 2019, 3:40pm

Interesting idea ! How can I do that with HA script ?

claytonjn · May 22, 2019, 4:08pm

The documentation for the “unofficial” API is here: https://rithvikvibhu.github.io/GHLocalApi/#assistant-assistant-notifications-post

You should be able to set up a command_line switch like this:

- platform: command_line
  switches:
    switch_name:
      command_off: >
        curl -H "Content-Type: application/json" -X POST -d '{"notifications_enabled":true}' http://<IP>:8008/setup/assistant/notifications
      command_on: >
        curl -H "Content-Type: application/json" -X POST -d '{"notifications_enabled":false}' http://<IP>:8008/setup/assistant/notifications
      command_state: >
        curl -X POST http://<IP>:8008/setup/assistant/notifications

They Amazon Polly voices are quite nice. You can use them for TTS on your Google Homes.

Julien · May 23, 2019, 9:09pm

addon stopped working for me. worked great for many weeks and stopped couple of days ago.
following request is well received http://xxxx:5000/broadcast_message?message=bonjour
DEBUG:root:None
INFO:werkzeug:192.168.2.140 - - [23/May/2019 21:03:05] “GET /broadcast_message?message=bonjour HTTP/1.1” 200 -
but nothing is played on the google home.
I’m wondering if I’m not in the same case than what is described in the following thread:
https://support.google.com/googlehome/thread/2964730?hl=en
Anyone with a Gsuite account, for who this is still working ?
way to activate more debug ?
Thanks in advance for any help. Would be very sad to have to switch to TTS, addon was much better …

Patrick · May 23, 2019, 9:48pm

Yes, this is a recent problem specifically related to G Suite accounts. I had the same problem and contacted Google support. I suspected it was a Google problem because if you tell one of your GHs to broadcast a message rather than playing the message on all GHs except the originating GH, it does the exact opposite and only plays it on the originating GH. Long story short, Google have acknowledged that this a bug affecting G Suite accounts.
My fix: set up a normal gmail account and authenticate that to this add in. Bonus is that if you set the first name of the gmail account to “Home Assistant” then when the add on broadcasts a message you will hear “Broadcast from Home Assistant…”
