I’ afaid that emulate speach will stop functioning april 1, see End-of-life of Homey’s speech recognition - Check your Flows.
I like the thought of the IFTTT route. I do not like that IFTTT is not available in Dutch for Google Assistant. It’s too bad there’s no way to execute a flow by a name text field. I do thing that this is something that Athom could add quite easily as an alternative to Emulate speach.
