piCorePlayer / default playlist

I have the following environment

3 Raspberry Pi, all of them with piCorePlayer.



The first one runs the LMS. This one also has a display and jivelite and squeezelite is running.

The other two pCP´s are only players. Both of them are players for a BT-Speaker, so i have in summary 5 players

Player one
Player two
Player two BT
Player three
Player three BT

I have build a Group with the Groups Plugin called 1st Floor. This Group has two members, Player one and Player two BT.
Now the following happened.
I give power an the BT-Speaker. The BT-connection with Player two is build. When the connection is established and the Player two BT exists he becomes a member of the Group 1st Floor. On Player one the display is going on and the last playlist is working. In 90% of all cases it is a Radio-Stream.
When i turn of the power of the BT-speaker the Player one is also going off(stop playing and display off).
And now it is not possible to play the last Radio-Station on player one. I turn on the player one, i see the last Radio-Station but when i try to start playing it doesn´t work. I had to choose another Radio-Station or a Track of my musik on the NAS and then back. It is not a Problem but not a goal for the woman acceptance factor:-)

What can i do to play the preferred Radio-Station at every time when i start Player one regardless of how the player is switched on(tap on display, power on on the website)?

best regards,
