Hi there,
I have created a newer version of MMM-Slack which I have called MMM-Slack2. I wrote this module because of the changing API of Slack.
Until now, the events API has not been implemented yet, so the module will not immediately refresh when a new message has been sent to the channel. It only gets new messages periodically. A guide on how to use the module can be found on github.

I use this module to have a simple way to display messages in a house so that they can be read without having to use a smartphone.

Feel free to try out the module and send me your feedback. If you have any ideas for new features or if you can help implement the Events-API, please contact me

So I have tried to update node (v12.x) and voilà, now it works like a charm! Thank you for your support and this awsome module!

Thank you for your support. I will try to update node and see if that fixes the problem and/or if running it via ssh changes anything when I am home again next week.

Hi,
thank you for the overall looking of the JSON string. I checked it, it was not in this format. So I chose “Desktop” and now I got a credentials.json file that looks like your example. Then I tried again with a fresh module install from github. It still did not work.

Here is the debug-log, that I get from npm. I hope you can help me with that.

Hi,
first of all, I really like the ideaof the module. But I am currently stuck at creating the authentification with google and then the token. In step 7 of your readme, I have no “other” option to choose, so I chose “web application”. But in step 9 (using VNC to access the magic mirror), the authentification fails.

Do you have any idea what is my mistake?
