Hey Guys,
i tried to write a simple Programm to change the angle of my servo with the "pi gpiod" node on my Raspberry pi. In the debug window i just get the message: "Error:connect ECONNREFUSED 127.0.0.1:102". I hope there is any help for me.

Are you sure that you are using the right IP port? The default appears to be 8888?
Port 102 is a privileged port number and you would have to run gpiod as root to have that.
I use 8888 in the pi gpiod node
But you are trying to connect to port 102 which is clearly wrong. Does the node have a setting for the port? I don't use it so I don't know.
There is a possibility to give the host. Ive got there "localhost" and "8888"
You have to run the pigpiod daemon in a separate terminal session
sudo pigpiod
The node will then connect to that running daemon and it will work (went thru same process myself 4 days ago ) 
Hello cymplecy, where have i to write in the command? In the command window of the rasperry pi?
Yes - launch a terminal and type it in
I get "Can't lock /var/run/pigpio.pid" and "Can't initialise pigpio library"
Is this a standard Pi running Raspbian?
Just noticed that your getting a strange port number - got this message before I fixed mine
I can get that error by running the command twice
Can you switch off and on again and try it again please?
I restarted the pi and got the error again, after i wrote the command
I have the Raspberry Pi 3 Model B Vi 2
restart your pi - dont run the sudo pigpiod command - run this instead and see what it gives
sudo ps aux | grep pigpiod
i think that worked. What should i do now?
Can you post the output of it please
root 331 7.6 0.1 9976 1636 ? SLsl 16:01 0:39 /usr/bin/pigpiod -l
pi 3006 0.0 0.0 7360 576 pts/0 S+ 16:09 0:00 grep --color=auto pigpiod
So that shows its already running - I wonder what is starting it?
But never mind - at least its running
So - if you start node-red - are you still getting the ECONNREFUSED localhost:102 error message?
unfortunately yes, i get that error message
I am out of ideas at this point
Sorry
