I have an ‘alarm clock’ flow waking me up in the morning with a radio station stream.  
I try to make a flow that gradiently increases the volume (see image) but it doesn’t seem to have any effect. The Chromecast Audio dongle seems to stay at the latest volume level that I used.  
Could anyone verify this?  
It should be possible, right? Since there is a card option that says ‘Set volume to X %’.

Answering my own question based on tips from the ‘Homey Homies’ group on Facebook - I have probably misunderstood the timer function - all the cards start at the same time, so instead of putting  
after 10 sec  
after 10 sec  
after 10 sec  
I should try with  
after 10 sec  
after 20 sec  
after 30 sec
