You have to change the Documentation an move the apiKey to the config part.
In the java-script you check on self.config.apiKey

I updated to new version, and requested the API Key, Changed the config file and added the apiKey from CoinMarketCap.com. Also rebooted the MagicMirror.
I still get the message : “Please provide an API key”

I have the same issue. Also multiple reboot did not help.
Still message “Unable to get data from CoinMarketCap.com.”

@tbouron

I do not have more log. At startup no errors. Yes I have all on the latest version 10.6.1

@tbouron thanks for your feedback.

All the Sonos devices are online and the MagicMirror ison the same network.

Re: MMM-Sonos - Display what is currently playing on your Sonos network

When I start the MagicMirror, then your Sonos module creates the following Error:

[10:19:19.329] [ERROR]  [Error: ENOENT: no such file or directory, open '/home/pi/MagicMirror/modules/MMM-MyWastePickup/schedule_custom.csv'] {
  errno: -2,

}
[10:19:19.335] [LOG]    MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
