+Damit der Pi User die Rechte hat die Prozess Prio neu zu definieren braucht es folgendes:
+  * ''sudo apt-get install libcap2-bin''
+  * Python venv anlegen mit ''%%--%%copies'' sonst hat man nur Links auf Python !
+  * ''sudo setcap cap_sys_nice+ep _envR/bin/python3'' \\ Es gibt da noch 2 weitere Varianten ... Die ggf. auch setzen!
