If you're interested in something more generic, check out if https://enso.org could be worth a look! Thanks to GraalVM, you might be able to import JS packages too, among others (Java, Python, & more...); OTOH with the caveat that the project is still in ways in-dev...

I've been following Enso since it was Luna. Can you be a bit more explicit about 'in-dev'? Not to be used yet in production? Thanks.

Actually I'm kind of glad it's difficult to do those sort of things in Chrome.

There are fantastic reasons why it should not be allowed on random local devices, unless the local device is configured with some sort of authentication... but the problem now is that total ban on accessing local devices from a secure web app is a serious choke point for anyone trying to develop something to control appliances outside the walled garden. Fascinating discussion here with a Plex dev expressing similar f…

Dumb question. Why not just get a free subdomain and get a letsencrypt certificate for each device?

Obligatory comment that Huginn is also useful for similar applications albeit less home automation than web automation

Huge fan of huginn, I've started running n8n and huginn on the same box recently. Some of the huginn modules are a little more work to use with common SaaS offerings. I'm hoping together they can cover basically everything I want, although I don't do any home automation.

Node-RED co-creator and project lead here. Happy to answer any questions you have.

I’ve been looking at building an auto remediation system for server alerts, is Node-RED a decent system for this? It will probably start with just triggering some kind of ssh command to run a script.

Cannot find if it supports any version control? Does it?

It does (everything is saved as json), but it's a bit of a hassle. Scripts are saved to a single line, so you really need a plugin that breaks them up. It's really pretty silly that isn't the default. The other huge PITA is that touching a node in the UI causes the json to update even if you didn't do anything, and changes will often cause nodes in the json to reorder. That makes git commits very cluttered. Merging i…

I've run into these issues as well but haven't come across those packages. What plugins are you all using?

It originated in that space, but the ecosystem has taken it in very different directions. It has lower-level abstractions than n8n (which focuses on automating third-party SaaS), but can arguably do the same. I've used it for an insane amount of things, starting with home automation and telemetry but also fairly sophisticated uses, including: - Sniffing for multicast streams on a LAN and exposing IPTV set top boxes a…

> - Building an RSS aggregation and transformation pipeline that does translations, scraping, etc. About how many feeds are we talking here? One per hour? Ten? Some hundred? I've thought at some point doing similar, but was not sure whether node-red or similar tools would perform well enough with this kinds of jobs.

My OPML export is over 200 feeds, and they're all being fetched and handled there.
