For Google I was able to solve it the following way:
- Create a Routine (partial equivalent of “shortcut automation”) that let me say “Hey Google, Chatbot” which autostarts a flow sending an email to my mail address, then I can dictate the message and say send.
- Then on my email server I have an option to direct incoming mails to a program, in which case I sent it to curl that forwarded it in a POST message to a webhook I created on Homey.
Thus once Athom has approved this application I will send out a follow-up version that will allow you to talk to ChatGPT through a webhook in addition to using flows. I suppose someone else might find it helpful too.
