Hi,
I have google home talking to my node-red flow using the library ([node-red-contrib-alexa-smart-home (node) - Node-RED](https://flows.nodered.org/node/node-red-contrib-alexa-smart-home)). It is great for switching on outlets and lights but it currently can't get sensor data. I was wondering if anyone has been able to do this with another library. Basically I'd like to ask google for a sensor reading and convert that into either an MQTT message or a database query (might be simpler?).
I have looked back through the forums and the only thing I can find is
> [@Querying data from a sensor via Google Home?](https://discourse.nodered.org/t/querying-data-from-a-sensor-via-google-home/7833):

> Hey there. I have a running instance of NR and the bridge to GH made by @i8beef which is working great. I wonder if there is a way to ask to GH for values that can be accessed via MQTT from my sensors such as "Hey Google, what's the humidity in the flowerpot?".
which doesn't quiet suit my needs.
Thanks in advance,
MArtyn

I'm using [node-red-contrib-googlehome](https://flows.nodered.org/node/node-red-contrib-googlehome) which is similar to `node-red-contrib-alexa-smart-home`, and which I believe is written & maintained by the original author of the node which you are using (@hardillb).
Both nodes seem constrained by the [available 'devices'](https://developers.google.com/assistant/smarthome/guides) published by google, so any sensor device needs to fall within one of their listed categories.
For example, I have a temperature sensor in my garden, and the nearest device type I can find is the **thermostat** device which _almost_ works!!
I can ask "What's the temperature in the garden", and Google Home will reply with the current temperature, but also insists on telling me what temp the 'heating' is set to (which of course is not required).
_Frustrating!!!_

It seems like sensor should be where it is at?

I agree, very frustrating1

I've been playing with the device type "Sensor" which I can get to just return current temperature. I just need to find the time to add it to the list of device types on the site

That's good to hear. Thanks Ben.

Just a quick question, can your node be used to trigger an mqtt message to control a tasmota device? I was just going to see if I could replace my instances of node-red-contrib-alexa-smart-home node to give it a try.
Thank you, Martyn

Of course.
You may need to transform payload to match what ever the tasmota is expecting.

Is there any update to this please @hardillb

Update should be live along with an updated device/trait editor

Great! Now working here, and reading DS18B20 equipped devices in the garden & greenhouse.
I had a few initial setup problems, but all my own fault - I overcomplicated the flow.
I assume from your notes that you are not expecting the Google home app to display the value at this time.
