I personally don't have use for the insight to this "obscure" tech stack but typically the more obscure the tech stack the more people can benefit from you sharing your perspective.

If someone shares their additional take on rewriting in rust (I say this with love as the type of person to do that) it doesn't add as much value because many of those experiences are shared regularly. If you share your unique tech stack, the people in the woodwork who might be struggling to do something along those lines but can't find the resources will benefit way more.

So you should!

Also can you elaborate on the CAN bus part of your smart home? Is your car wired into your home network?
