How to send a message(String) from Alexa to ESP32? #154

Closed DeathStrokeAlpha-VA closed 3 years ago

DeathStrokeAlpha-VA commented 3 years ago

I have built a gateway that works on ESP32. The gateway controls the peripheral devices via ESP-NOW protocol. Is there a way by which Alexa can simply forward a string to ESP32, like, if the user says "Alexa, turn on light in kitchen", then, Alexa should forward "TURN ON LIGHT IN KITCHEN" to ESP32.

As I understand it sending a string like you asked is not possible.

If you look at the callback function you can see what is and is not possible at the moment: fauxmo.onSetState([](unsigned char device_id, const char * device_name, bool state, unsigned char value)

The bool state can only be true or false. The unsigned char can be 0-255. Fauxmo emulates a Philips Hue, according to the documentation, so you can only da what you can do to a light. In this case switch it on and off and send a value (for brightness I assume, originally).

I'm not sure what more is possible with more coding work but as I understand that's what we have right now.

Thanks for the answer but I think this isn't possible with Alexa. I would have to create an Alexa Skill and point it to my MQTT server.

Yeah, not directly possible without creating an Alexa skill. Having said that, you can interpret what the command was by what the values are as @sebkouba said.
