hi,
I would like to use node red to interact with voicemonkey and home assistant in order to launch announcements on my alexa devices. To do this I need to launch actions such as rest on home assistant as shown below:
If you want to use HA then as @Paul-Reed says their forum is the probably the best place to ask those questions.
Saying that you can send voice, text and announce commands direct from node-red to Alexa using node-red-contrib-alexa-remote2-applestrudel (node) - Node-RED nodes, why envolve HA at all.
