A new standby mode is introduced in firmware 537.
When connected to mains - the speaker will now enter standby after 30 minutes of inactivity and the light in the Touch interface is dimmed to a dot.
To wake the speaker from this new standby mode - simply play the speaker.
I would like to bypass this feature when my Zipp is plugged in. Working from home, listening to music all day, when a song/album ends, and after 30 minutes I want to play a new one, my Airplay connection has to be reestablished because the unit went to sleep. It may be a fault of Airplay or the Zipp, but that re-connection to Airplay doesn't always work right away. Sometimes I have had to restart the Zipp. If it didn't sleep in the first place, my life and love of my Zipp would be much better.
I agree that there should be an option to turn off Standby Mode when the unit is plugged into power. Almost every morning the past month I have to reconnect my ZIPP 2 to my wifi and waste time.
I would love to turn off Standby Mode because Spotify gets disconnected if I pause music for more than 30 minutes. Please, please add this option.
