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.

[–] EarMaster@lemmy.world 7 points 2 months ago (2 children)

May I ask why you consider n8n risky?

[–] statelesz@slrpnk.net 18 points 2 months ago* (last edited 2 months ago) (1 children)

Just look at the recent vulnerabilities it had. It just had a CVE 10 in January and March of this year.

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.

[–] anyhow2503@lemmy.world 3 points 2 months ago (1 children)

Is there a version of n8n without AI generated code?

[–] irmadlad@lemmy.world -2 points 2 months ago (1 children)

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.

[–] anyhow2503@lemmy.world 1 points 2 months ago (2 children)

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..

lowcode environments are the O.G slop.

[–] irmadlad@lemmy.world 2 points 2 months ago (1 children)

Wow! Well, you can keep your attitude.

[–] onlinepersona@programming.dev 1 points 2 months ago (1 children)

That is a profound misunderstanding of AI, wow.

[–] greyscale@lemmy.grey.ooo 0 points 2 months ago

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.

[–] ISOmorph@feddit.org 18 points 2 months ago (2 children)

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.

[–] captcha_incorrect@lemmy.world 4 points 2 months ago (1 children)

What do you use for OCR parsing?

[–] ISOmorph@feddit.org 3 points 2 months ago

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.

[–] HerrLewakaas@lemmy.world 1 points 2 months ago (1 children)

Why screenshot and parse? Can't you just parse the html directly?

[–] ISOmorph@feddit.org 1 points 2 months ago (1 children)

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.

[–] HerrLewakaas@lemmy.world 3 points 2 months ago

What why, I'm scraping html just fine

[–] irmadlad@lemmy.world 5 points 2 months ago

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.

Tons of things 😊

  • Built quite a few personal agents, long before OpenClaw or whatever that is
  • Automated Social Media Images
  • Set up a bot on Manifold Markets
  • Created entire processes in our company using it for Sales, Marketing and Customer Support
  • Automatically update the CRM using Macrodroid and n8n
  • tons of other playing around.

One of the most amazing pieces of software I've ever used.

[–] sixty@sh.itjust.works 2 points 2 months ago (1 children)

Can you elaborate on the agents? How do you handle persistant memory, what triggers them? What are they for? ☺️

[–] dalekirkwood@lemmy.world 2 points 2 months ago

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.

[–] Smash@lemmy.self-hosted.site 1 points 2 months ago

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

[–] qaz@lemmy.world 1 points 2 months ago

I personally use Node-RED for several automations myself. Is it worth switching to n8n?
