I personally would love that
I still begging my friend for code to some simple nodes where I want to avoid esphome. I use mysensors only through cables with serial and planning on rs485 or maybe pjon if tests are finished.
The yaml support will be nothing new for homeassistant user and probably.not much learning for others.

Hi
What is your persistence path in configuration?
I have sometimes errors in logs about path

Hi any progress on this? I am looking into documentation and eventually find this thread

In this case I have question why? I Know that why not and because I can is good enough answer but...
You can have best from home assistant (install Hass os) and mysensors (make gateway on separate Arduino). And this way when you want to upgrade to something more than RPi you can do it with minimal damage ( I did it this way and it was quite nice upgrade). But this is only myn2 cents

I think that you have concept problem. First I don't think that raspbian install have any sense at this stage. There's so much more you can do with hassos ( docker). And second why you doesn't connect gateway via USB an use serial connection. I use Arduino mega directly via USB and it is very stable. You have to add in configuration mysensors with path to USB (I recommend serial number identification).

Hi great work!
Any chance for your sketch? There isn't many working sketches (without many errors in log) for home assistant. Unfortunately I can't write code.

Hi
I have different question doesn't this line give you errors?
persistence_file: '/config/myhouse/mysensors.json
