Google Assistant: get Home Graph traits for all devices

General
1

Hi,

Is it possible to read out the Google Home Graph to get the state of connected devices?
For example:

  • Can I get the destination temperature of my Nest Thermostat?
  • Can I get the remaining time of a running Timer on my Google Home?
  • Is my Hue light on at the moment?

I know there are several custom nodes to create 'virtual' devices on Google Home and interact with them. (eg: node-red-contrib-googlehome, node-red-contrib-nora)

But as far as I know, those interactions are only possible with the created 'virtual' devices, not existing ones.

Nest had a nice API but that's deprecated ... There are no alternatives yet, as far as I know?

Thanks!
Gert
