Google Home - Node Red = TTS

[korniza]

Hi @ all,
I try to build a virtual device with a text sensor that can be used as an input to node-red using the google-home-notification node. It is too easy to install and use node-red so comparing to other implementations it did not require a middleware to send the tts to google home.
My issue is that I need to build a dzvents script and parse the text of the text sensor via MQTT when value (text) changed.

Any help?

Not sure what you are asking, but if it is how to get google home to read out sensor data/switch status etc.. follow this guide -

viewtopic.php?f=4&t=13607&start=20#p148867

Or this one

http://www.domoticz.com/forum/viewtopic ... 20#p150149

If you are using the google home notify node instead of the chromecast node, just substitute the text in the speech function to something like....

msg.payload = 'the '+msg.payload.Name+' is '+msg.payload.Temp+'degrees'
return msg;

Or whatever your "text" is.

Thank you Bradds for answer. I have no idea about this setup. My request is kind different as I want to use GH to perform automatic notifications. For example if CO2 is higher that 1000ppm, to send a tts on GH and warn me to open window for fresh air, or warn for a forgotten bathroom light was left on. So I do not want to ask Google home for a status of device.

What you are describing is exactly what the guides in the last post do.
The only difference is that the "status" switch is activated from an IFTTT command via Google home.
You can substitute the "status" switch for any switch or command from domoticz that you want.
Then once the command is filtered in Node-red you can get google to read out whatever you put in the msg.payload, be it text, status etc.. etc..

To do what you want, follow one of the guides listed (omitting the IFTTT part) , then just create a virtual switch in domoticz that gets activated once your conditions are met via a script/blocky or whatever means you choose. Filter out your switch in node-red and then get google to read out a warning.

Here is an example for when a front Door PIR is activated, then google alerts "Someone is at the front door" same methodology applies for any switch/device/script

Or ....

You could do it all in node red by filtering out the data from your CO2 sensor to activate a node once it reaches a certain value, upto you which way you go.

Here is an example of a warning if the bathroom light switch is on for a set period of time, change the idx to your bathroom switch and adjust the time in the trigger node. The trigger node gets activated once the switch is on, and alarms to google if the time lapses. If it receives an off signal from the switch in the meantime, it cancels the warning. I have included on/off inject nodes for testing purposes. Have a play and you should get the idea. The on/off filter node is not necessary, but handy if you want to use it to switch something else from the command.
