I’m interested in piping TV audio into some kind of house-wide speaker system. I’m looking forward to hearing if and how you did that.

Anything that does the job would do the trick. I’m not sure how you’d use Wireshark for this purpose, but C# is certainly a possibility… if you feel like doing 10x more work.

Do I have to use Node Red for the coding or would something like Wireshark or C# also work? Just wondering whether I should learn Node Red or if I have other options that I already know how to use. Thanks!

I’m sorry you feel that way. But the “modularity” is a feature, not a bug, and you may be expecting something different than I’m trying to offer.

This post is more eye candy than content, because it’s really a combination of many other projects on the blog. But ~30% of the content of this blog is > (according to WordPress stats), and I maintain 3 separate open-source projects that spun out of this site. So the hardcore source-code is all there, but often times it is behind a link (e.g., Github repo with a README).

It’s true, though, I aim to provide “concepts” and “inspiration” (NOT a pre-built solution). I learned the hard way that it’s huge waste of my time try to make a “copy-and-paste” sort of blog post. My early blog posts were thousands of words long “complete guides,” but people really did not like them very much — because they were so specific to my situation and my hardware, they weren’t useful.

You have a very frustrating style of documenting a project. You don’t explain a project from start to finish. Constantly throughout the reading are overlapping “Related: …Read More” dialogs that go off on a tangent and loop back to the starting page. Circular looping with no resolution.

In the end, you only discuss hardware parts individually and never explain how they connect together with the Raspberry Pi. And you never show the source code for programs you had to write to make it all work.

Hi Terry! The bi-directional audio is achieved via the loudspeaker. It works exactly like alerts, except instead of piping an audio file (like “doorbell.wav”) into the snapserver, it pipes the microphone input. I’m hoping to package this all up into an easier to use HA component at some point. But if you’ve gotten the loudspeaker alerts working, the microphone is very trivial.

Hope that helps! LMK if you need more clarification.

Hi there,

At the beginning of the article, you mention, “a night-vision IR camera with a microphone built-in. Throw in a tiny USB speaker, and we have bi-directional audio.”

I can’t seem to find anything about setting up the bidirectional audio in the article, or the linked ones. Can you point me to the right place, please?

Good luck! I did add some more links in the post in hopes it would be helpful.

OK. Thanks for the reply Zane! I’ll see what I can screw up!
