With the sunset of DTH, I’ve been looking for an Edge driver replacement for my integration with Fully Kiosk. My primary use case is to send text-to-speech to my wall-mounted Fire tablets when certain events occur (ex: garage door opening or doors left open too long).
I found that pairing ST routines with an Edge driver device that can sent http commands does the job for me, and I found this Edge Driver to post web commands to my Fire tablets. [ST Edge] Web Requestor: a driver to issue local POST and GET HTTP requests
If this solution helps anyone, or if people have questions on how to set this up, let me know.
