I've seen lots of threads about integrating Tasker with connect iq apps and after making the switch over from pebble I finally figured out how to call Tasker tasks without needing to use IFTTT or any web based service.
Inside your so or widget map the function Comm.openWebPage("http://taskName",{},{},); to button presses or any other type of interaction.
In Tasker, create a profile using the event autonotification notification intercept as a trigger, with the filter of notification text containing " wants to open http://". For the task that this triggers use variable spilt on %antext with a splitter of "http://". Add action perform task with the task name being %antext2. Finally, remove the notification from your phone with Autonotification cancel action, cancelling by I'd %anid.
You could probably do the same thing using the native Tasker notification intercept and cancel actions too.
If you need help understanding further feel free to message me and I hope to see more former pebble developers join me here to help grow the community and share knowledge.
