Thanks for the reply.
these smart screens are beautiful.
the only one that comes close to what I have to do is the meta portal but only for the backup battery in case of power failure.
I have to make an alarm clock and a music player, the wireless NTP function for the alarm clock is also essential, and the weekly programming of the alarms is also essential.
then as regards the music player it would be nice to use a DAC and an amplifier of my choice, certainly not that of the smart display which has small speakers and an unknown audio sector, I tried to search the network for hardware details but nothing is found. or transmit through the wi-fi to some wav player module or to a chromecast.
