Thanks for all help. I found the solution.
Since SFOS 5.0 the name at the android suport service are changed.
To start/stop aliendalvik or new the AppSupport the comand line should be formed so:
sudo systemctl stop appsupport@defaultuser
sudo systemctl start appsupport@defaultuser
Now I can bring it to Situation for sleeping mode in the night.
I hope it helps also other Situation users…
