LOL, glad you could read it. Was out and didn't notice how Siri had mangled my response.
Anyway, I believe TTS isn't possible with VLCThing, so that would be a pre-recorded response to trigger Alexa needed. It's reliable, just a bit of a trick needed to get it working at first. I run mine on an old laptop that also runs the Node.js server I use for Google Assistant Relay.
For sure the VLCThing is easier to setup, but the benefit from Google Assistant Relay is much greater. You can get TTS in the Google voices, and you can send silent messages to anything that Google supports by adding [CC] the beginning of your TTS phrase in Hubitat. So anything that isn't already supported by IFTTT or is too slow via IFTTT, but is also supported by Google, is controllable. Couple of examples I used this for is controlling an August Smart Lock, Changing colors of a Trådfri color bulb each day at random via Hue bridge, and activating a virtual motion sensor in the SmartThings cloud, that in turn triggers an Alexa routine to announce when my door opens.
It's not super hard, and the directions are well written, but it's for sure not as simple as VLCThing.
