Following up from my earlier thread.
On Saturday I was playing with the integration with one of my GH's.
I could click on Volume up, down, set volume and speak and the GH would respond.
Today I tried Volume up, down, set volume and nothing happened. Nothing in the logs.
Put "Testing" in the speak text box and press speak and sure enough it spoke "Testing".
Now when I press Volume up, down, set volume the GH responds and does what it should.
If I press Stop then things do not respond again. Press speak again and things work again.
In the device you can see the media source change from Hubitat to None.
Here are the logs.
This may be the correct behaviour but just thought I would raise it to see what people think.
