Are you doing anything cool with n8n?

Just curious what people are using n8n for.
I just finished setting up a workflow that sends me a Telegram message every night about photography opportunities for the next day. It puts together weather data, POIs (which I defined for my location), sun/moon position, milky way visibility, cloud cover, etc. The message then simply tells me if it’s worth it going out in the morning.

I’m not willing to run something that risky on my own infrastructure, therefore I wont run it. I can do all of those things with a handful of scripts or Home Assistant anyway.
May I ask why you consider n8n risky?
Just look at the recent vulnerabilities it had. It just had a CVE 10 in January and March of this year.
app.opencve.io/cve/?vendor=n8n
Almost all of them affect authenticated users. The only ones that allow unauthenticated users access are for old versions. So to be honest: I am not that much concerned.
You aren’t concerned about a severity 10 vuln? Those are found in software with exceptionally bad qa and abandonware. That should give you pause about how hard n8n is “going fast and breaking things”.
Well, this “authenticated user” could be your fucking LLM and this is really concerning. Besides that a single CVE 10 is also very concerning no matter how old the affected version is.
I’m not a slop jockey and I’m watching people plug these kinds of things into public data and having it do operations with financial/business impacts.
I’d rather employ a gremlin to write scripts.
Are you aware that you are not required to run AI with n8n? There are two flavors: With AI and without.
lowcode environments are the O.G slop.
Wow! Well, you can keep your attitude.

That is a profound misunderstanding of AI, wow.
No, you’re thinking I’m at the low end of the bellcurve here. When you actually understand what the transformer is doing, you’d understand.
What you’re really doing here is showing yourself to be a mark.
Is there a version of n8n without AI generated code?
If you are asking if you can run n8n without AI, yes. That’s what I run. If you are asking whether n8n is free of any AI generated code used in it’s creation, I couldn’t speak to that.
I see. It uses AI generated code, I just checked.
This is going to be a very difficult hill to die on as time goes on..
OK cool.
A governmental-ish site I’m required to use doesn’t push notifications as mails, so you have to login daily to check for updates. Updates may happen multiple times daily or once a month. I automated my server to access the site once a day with my credentials, screenshot the notifications, parse them with ocr, and send myself a mail.
What do you use for OCR parsing?
The data is non critical and doesn’t contain indentifying info so I use ocr.space API. You could probably find ways to use the tesseract libraries locally.
Why screenshot and parse? Can’t you just parse the html directly?
Since the dawn of LLMs it’s virtually impossible to scrape web content. Headless browsers have become basically useless. I actually have to automate keyboard inputs to simulate the navigation. I could maybe try to write the javascript cache to file but honestly it’s just faster that way.
What why, I’m scraping html just fine

That’s pretty cool OP. I use n8n for various automation around the lab but the most recent would be an addition to my dashboard. The n8n routine will fetch the latest, animated, Solar Flare and Aura Forecast from sol24.net. I’ve always been fascinated with the sun and our atmosphere since I was a kid.

I use it for just two things, triggering a download with a docker tool over a webhook call I use in a userscript and calling a webhook of a media server on local file changes
Tons of things 😊
One of the most amazing pieces of software I’ve ever used.
Can you elaborate on the agents? How do you handle persistant memory, what triggers them? What are they for? ☺️
n8n offers some cool agent features out of the box.
Like, if I talk about my personal agent is connected to Telegram, it can access my emails, my calendar, it can do web searches, deep research, it can access a NocoDB instance. etc. It also records a journal, any food diaries, it can take handwritten notes and convert them to text and store in my obsidian vault.
For memory, I use the standard one from n8n but for long term memory, I use NocoDB or some vector storage (I forget the name).
Honestly, it’s very easy to get started and play around with, so I recommend just setting up an agent and just having a go.
I personally use Node-RED for several automations myself. Is it worth switching to n8n?
