Issues with frontier silicon device in Automation

Good morning,
I´m struggling with a frontier silicon webradio device in my bathroom. It supposed to turn on wenn I turn on my smartphone in the morning, but it doesn´t. It´s in some kind “not-on-not-off” state.
However, I can turn it on and off manually from the gui.

This is from the logbook:

> 7:41:02 radio-badezimmer changed to playing
> 7:40:58 radio-badezimmer changed to unknown
> 7:40:54 radio-badezimmer turned off
> 7:40:20 radio-badezimmer changed to idle
> 7:40:18 morgens-radio-an has been triggered
> 7:40:18 pixel4xl is at home

At 7:40:18 i turned on Wifi on my smartphone, the automation triggers and the radio should turn on, but it remains in the “idle” state

At 7:40:54 I turned it off and on again manually.

This is the automation (1 of 2, same happens in the other one). Is there maybe another way to turn on the device?
