Jemery, thanks for your fast help!
After the GameFrame was disabled via IFTTT yesterday evening the light on the WiFi-Adapter remains connected (cyan “breathing”).
As I checked the LED again this morning, it was completely off.
I thought I updated to your latest firmware some weeks ago. The version listed in the web interface is “System version 0.6.2”. I did not found any other version string like “20170523”. Is it the correct place or is the firmware version not listed in the user interface?
Have a nice day,
Andreas
