Then I'm really glad I started this thread 😁 - I'm happy to feed your passion!

No, that's OK, I use "devices" as my root as that makes more sense. You will see from the new thread what I'm trying to achieve.

> Hi again! As mentioned in the last of my topics, I need to better understand how to use and whether I can use the Homie Convention nodes. Here is what I'm trying to do. I have a load of old wireless switches and plugs, an external sensor and a wireless doorbell. All of these use 433MHz and date before cheap ESP devices wink. I use an RFXtrx433e USB device with Max's super excellent set of nodes to capture data and transmit commands. What I want to do as I'm working on the next generation…

I think that was what I was confused about. I probably didn't read the docs properly.

I suspect that we may have some more conversations about the best use of the convention. I'll also be interested in your thoughts about best use of nodes vs properties. But I know I need to read up more about v4 of the convention - lets take things to the other thread.
