Error installing Yolink NS

[MrMike]

Hi, I am trying to install the YoLink NS (PG3 v 3.1.16). I have added the key and secret, but cannot get the node to start. It starts and then immediately disconnects. I am also unable to pull a log, as I get an error that the log is not found.

Not having a log available is a good indication that the node server is crashing on startup.  In most cases, this would be because it didn't get installed correctly or something it needs is missing.

I'd suggest that you try re-installing the node server (node server store -> select YoLink -> click the install button -> select the re-install to existing slot option.

If that doesn't allow it to start, download the PG3-log package and attach it here.  Also, including the time of day when you did the re-install will help when looking at the log to narrow down what part of the lot to look at.

Is there a log for the PG3 it self you can provide. 

There may be an issue with installing on of the python libraries.   

I am travelling and am not back until the new year so it's difficult to debug - especially without a log being generated

Thanks Bob, and Panda,

 

I'm gathering this is the issue?

I had the same symptom due to psutil not being found during YoLink installation. The solution was to connect using SSH (using PuTTY for example) and installing psutil:

sudo pkg install py39-psutil

This is the thread about this:

Thanks very much. Yep, the pkg install squared it away!
