@Fabian : Everything checked so far is completely correct.
The only thing I can think off right now is to stop pimatic.
Then do a
sudo service pimatic start (which will fail I assume).
If it doesn’t fail but start correctly I’m really confused.
If it doesn’t start correctly, please do a
sudo egrep -i "pimatic|node" /var/log/syslog. This will check for all lines with node and/or pimatic in it and please check those for error messages.
If you find a message but it is not entitely clear from that one line then please do a
sudo grep -B 3 -A 3 "search term" /var/log/syslog. (will show the line containing “search term” and the 3 lines before and after)
Note that if the search term contains strange characters like
()<> etc. you might need to escape them.
