SOLUTION!

The MMM-MyCommute module instructions all work. Until you get to the API’s needed for this project. You will need to enable 3 APIs instead of the instructed 1.

1.) Maps Javascript API
2.) Directions API
3.) Geocoding API

after enabling all of these, the module should be working properly.

MMM-MyCommute: This API project is not authorized to use this API.

I went into console.cloud.google.com under Credentials>Maps JavaScript API.
I then restricted it to only use Maps JavaScript API, pasted the API key but error message above appears.

Edit:

MMM-MyCommute: The provided API key is expired.

New error pops up when deleting previous API and making a new one

Would this error only occur when saying the Activation word or would it time out after 10-15 seconds and show you the error. I also encountered a similar error message but not sure on what is happening either.

@Sean I did a clean install of MM again, added AssistantMk2 and Hotwords. Then added the line to the Hotwords config and the error still occurs.

Error message appears only when saying the key words to activate Google Assistant

I am running MagicMirror2 on a Raspberry Pi 3B+

@sdetweil How do I prevent from pm2 from starting?

When launching MM

• list itemcd ~/MagicMirror/

• npm start

before the mirror starts, this error message appears.

{ Error: listen EADDRINUSE 127.0.0.1:8080

  code: 'EADDRINUSE',

  port: 8080 }

However, on reboot. When saying the phrase “magic mirror” an exception is caught and stops any further listening from the mirror.

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
