Google is changing the known IFTTT integration:
Among other things, this means:
Google Assistant triggers that allow a variable input (i.e. text via $, or number via #) will no longer be supported!
This means: From September on the complete voice control of my home automation system (realized via Hubitat) will no longer work!
What I need: Speech recognation, where the recognized text is send to an URL.
BTW: I have installed a Google Mini in every room of the house to have voice control everywhere.
