i want to create a auto-on system to my sound system (receiver).
I do have an Amazon Alexa Dot (1. Generation) pluged via line-in (AUX) to my sound receiver.
As soon as there is sound playing on the Dot i want to auto-switch on my receiver.
For the auto-switch on i do have an Arduino with infrared LED, this is working.
However i am not able to detect active sound on the Dot, already tried to analyse the voltage on the line-in but there is a lot of noise on the signal when low volume music is played (high volume is working more or less fine).
Therefore the question: Is it possible to detect active sound / music on a certain Alexa device with a binding / addon in openhab?
If not: Do you have an idea for an alternative? Also no problem with opening the Dot and solder some wires
Thank you alot!
