how long can your pi last with the squeezeplug on?
i never turn mine on the 1st floor off. BUT it would play about 4 songs and then stop. i would have to use my android phone to resume the music. maybe my phone's wifi went to sleep? is the pi dependent on the phone?
i rarely use my pi on 3rd floor. but i notice it would die within 8hrs (not even playing any songs). looking at the log it is empty with this command: sudo nano /var/log/squeezeslite.log
did i forget to do something during configuration?
when music is playing and the pis are working perfectly, music is crystal clear with the default audio output on the board (pi model B)
