Is there a way to "broadcast" notifications to Google Home devices?

I would like to send out notifications in my home by using the google home "broadcast-feature".
When you tell google home "Broadcast....the dishwasher is done" it will be sent out to all devices.
If music is playing it will be turned down during the message and then resume.
This is what I would like Domoticz to do for me. I have googled and searched the forum and cant find a way to do it from Domoticz.
I have found some guides for HA, but not for Domoticz
Can you help me out?

I dont think domoticz support that natively like HA.
Personally I use for a long time relay assistant written for node js
https://greghesp.github.io/assistant-re ... roduction/.
It exposes the google assistant as a REST Api so from domoticz you have only to make an openurl with the relevant content.
The installation needs node js installed. Then you have to create a specific google action project (little bit complicated as I remember)

Thanks for the info. Sounds like a long way to walk for something that is just nice to have. I wait and focus on some other stuff

Relay assistant is still working and has been recently updated to include new google authentication rules.
If you have Node Red you can also use the node-red-contrib-cast module.

Maybe IFTTT.com is an option? A service to connect all kinds of other services....

HI, @swejmansson,
An easy method is to use Node-RED, as mentioned before by @mgugu.
Node-RED has multiple options to connect to Google Home (Assistant)
You can connect your Domoticz to Node-RED, either by HTTP (JSON) or MQTT (also JSON)
From there you can use one of the available Google Solutions, such as:
SmartNora (See:
https://flows.nodered.org/node/node-red ... -smartnora)
Google Smarthome (See:
https://flows.nodered.org/node/node-red ... -smarthome)
and others
SmartNora is a paid service, if you use more than 5 devices.
Google supports preprogrammed texts (See:
https://developers.home.google.com/clou ... ifications)
If you want free texts, you can create your own with Google Cast. (See:
https://flows.nodered.org/node/node-red-contrib-cast)
This will give you some stuff to read and to consider, which way, you prefer to go.
Regards

I wouldn't invest too heavily in Google Home, Google certainly isn't.

I use this node @FireWizard mentioned.
I use dzVents to send some mqtt messages to the Google device, so you have to send multiple messages to more then 1 Google device.
It is not completely synchronized, but it works flawless for years now.
