#2I remember trying to use it as a web-server few years ago.
You can see an example graph to get a user from the DB by id here: https://github.com/julius/node-red-contrib-sqlstring#example
Re: Node-RED: Low-code programming for event-driven applications
#3Because of Node-RED i learned a LOT about APIs, protocols and stuff in a playful way.
Especially:
-REST
-GET, POST, PUT
-JSON
-Javascript
-MQTT
And all that helped me a lot in my career, just because i wanted to automate a few things. And now Node-RED is just irreplaceable in my private life.

#4My friend uses Node-RED to automate and run a lot of devices/things in his van (which he lives in). I'm not sure if it's better to not have a programming background, because it's one of the more difficult environments I've helped someone with and the debugging when something wasn't working was really poor, it all felt very un-intuitive.

#5Even when you know how to script up automations, I still find Node Red invaluable for visualising and rapidly prototyping complex logic before you write a single line of code.
Plus, it is the perfect accompaniment to Home Assistant.

#6I use Node-RED in combination with home assistant, for automations.
It's sometimes overly complicated to follow the flows, or do something relatively simple, but otherwise it's a nice middle ground between built in YAML based automations, and something like AppDaemon which requires writing python scripts.

#7Yeah node-red really rocks.
Maybe I am biased as a particularly visually oriented person but i really enjoy the ease of prototyping with nodes and flows. I cannot help but sense that they may become more commonplace- there are applications for embedded sensing and data pipelines where it helps to think less in packets and more in streams or currents... also great for mocking up a synthesizer which I did with Paul Stoffregen's super rad audio tool for teensy/ARM : - )

Complex: yeah, especially if you find a twitch streamer that uses node-red to automate his stream. (for the curious: JvPeek [ger])

I find myself prototyping automations in Node Red before "productionising" the code in YAML. It's great for visualising flows but nothing beats automations running directly within HA. One fewer service to crash.

They changed the engine a lot so you can script the automations from the UI now.
