"Shortly" we had that topic here already: https://news.ycombinator.com/item?id=4441913 But most of the stuff is not alive anymore...

But there are some interesting new ones:

not sure if this is alive: https://sourceforge.net/projects/semanticwebpipe

Do you know some other (open source) event and agent system tools? (there are tons of commercial hosted IFTTT clones, they are not interesting...)

Node-RED seems similar and looks like it has a nicer interface (I've not tried it though).

Node-red also has a lot of connectors, from messaging eco systems to databases and is very flexible. If you hit a wall to the available node then you can always hand code Javascript in a function node.

The Raspbian Distro comes with Node-red pre-installed. Fastest and cheapest way to give it a try.
