I want to start by saying I am a huge fan of node red.
I have a mainly autonomous house build entirely on node red for the backend with uibuilder connecting to VueJS for the front end.
It runs across multiple PIs with a Debian server as the hub controller. A staggering number of connected devices (~350) and it works like clockwork!
I wrote some articles about it here: How I built an autonomous home using open-source tools | Aleks Milanov posted on the topic | LinkedIn
I also built a suite of Chatbots last year which still have more capability than modern LLM offerings: How I built a Chatbot using OpenAI's API | Aleks Milanov posted on the topic | LinkedIn
That said, I now do all my dev in Cursor and n8n (most recently).
I would love to go back to nodered in place of n8n, but I don't see that happening given the support n8n has for AI first.
This isn't an n8n sales pitch btw, I get there are other options like CrewAI or just good old python.
I wonder whether nodered will evolve to become AI first or whether it will remain the heart of my building management system and not much more.
