I built up2stream v3 pro into an old receiver. Everything works perfectly. There’s a little problem though. Using the fact that we can put the UP2S to sleep and wake up with the remote control, I would like to wake up the receiver at the same time by controlling the 230V relay.
Unfortunately, the CTRL_OUT signal is completely unsuitable for this in the state it is controlled by my U2S. Low when music is playing and high when nothing is playing.
Is there any firmware version that has simple functionality. When U2S sleeps it is low and when it is awake it is high?
