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.
You must log in or # to comment.
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.
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.
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?
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
