Hello everyone,
I’m trying to create an auto-on system for my sound system using an Amazon Alexa Dot (1st Generation) connected via line-in (AUX) to my sound receiver. The goal is to have the receiver automatically turn on whenever there’s sound playing on the Dot. I’ve managed to set up an Arduino with an infrared LED to control the receiver’s power switch, which works well when there’s sound. However, I’m struggling with reliably detecting when the Dot is actively playing sound.
Initially, I tried analyzing the voltage on the line-in signal. While this works somewhat at high volumes, it becomes problematic at lower volumes due to a lot of noise in the signal. This inconsistency makes it unreliable for my use case.
I’m wondering if there’s a way to detect active sound or music on the Alexa Dot using OpenHAB bindings or add-ons. If that’s not possible, I’m open to alternative solutions. I’m also considering opening up the Dot and soldering some wires to get a cleaner signal, but I’m not sure how feasible or advisable that is.
Has anyone else encountered a similar issue or found a workaround? Any suggestions or insights would be greatly appreciated!
Thanks in advance for your help!
Best regards,
[Your Name]
