For everybody with the same Problem, wait for starting the Set-Top-Box before start the enigma plugin f.e. Vu+ edit the /storage/.config/autostart.sh
Bash
#!/bin/bash
target=vuuno
port=80
a=0
while [ $a -eq "0" ]
do
nc -z -v -w5 $target $port
if [ $? -eq 0 ]
then
echo "Yes! Host is Alive!"
a=1
else
echo "Vuuno ist offline, try to activate.."
#if you have a automation software, this example send a remote cmd to the box
curl -s "home1/fhem?cmd=set%20harmony_38910441%20an"
