I use n8n self hosted @work and node red on my home assistant instance @home. Both have fantastic use cases but for me I don’t see any useful cases at home yet for n8n. Maybe some scraping of specific news items that don’t provide rss. Home assistant has a great direct addon of node red which let’s you integrate your entities directly with node red. Including notifications to the companion app (Android). @work n8n it is great for processing and optimiseing huge chucks of data for our webshop. It can use logins for office365 (yes I hate it and m$) and saved us a ton of work. Since a few weeks you can even store your own set of data in a light version database which is great for storing some reused datasets.
