Ok thanks. Can it do things like tell you when next train is due from a particular station etc? Also, can I literally say to it something like "Ok Google, play Radio 4" for it to just stream?
Guessing I need to buy a Chromecast Audio device for it to cast to a bluetooth speaker? Just plugs into the 3.5mm jack right?
Agree with Scam's last reply to yours. In particular, GH works directly with the ability to just play Radio 4 on your voice command mentioned. I play all my music through GH with my Google Play Music subscription. I simply say, for example, "Hey Google, Play .......(a particular song), or ......(a genre), or ......(an artist) on Google Play Music", or because I have set Google Play Music as my default music service, you can drop out the last words....on Google Play Music. If for example, you use Spotify and set it as your default player, it will play from that source.
You can also set up shortcuts. For example, if ........ is your favourite song, you can set it so it responds to your request for your favourite song.
Another whole new area for me was setting it up to sync my smart home. I use GH to control my smart lights, my Nest smart thermostat and my smart kitchen kettle. I expect it to be linked to Google Hello, the video doorbell, when it arrives on our shores early next year. Shortcuts also allows you to say: Hey Google, turn off all the lights or better, just Goodnight (and the lights turn off).
Yes, GH keeps getting better.
