I just installed Tasker, AutoTools, and AutoApps again and it worked as expected in Chrome and Fully Kiosk.
Hyperlink Configuration
As shown in the video above, I have a Hyperlink which is configured with the URL set to:
autotoolscommand://hello
The tile itself is using the default of ‘Open in Same Window’
Note that in Fully Kiosk, you would need to enable the Web Content Settings → Open Other URL Schemes.
Tasker Profile
Then over in the Tasker side, I created a new Profile → Event → Plugin → AutoApps and in the configuration, the only thing I changed was the filter to match my URL above (just the last part of it):
hello
Event Driven Alternative (Pushover/Pushbullet)
As alluded to in my initial post above, the hyperlink version of this is really best suited where you have a dashboard and you want to be able to tap on a tile to have it run some action in Tasker.
If you want to be able to react to events changing or have a SharpTools.io rule trigger things in Tasker, pushing the event down with Pushbullet or Pushover would be better.
This post includes instructions on how you can push events down to your phone from a SharpTools.io rule:
