ESP8266 WiFi Amazon Alexa Voice control Loxone

Amazon Voice Control


Functional Description:

  • Amazon Alexa Dot and NodeMCU work in one LAN network where they can "see".
  • The NodeMCU holds a keep-alive server on various UDP virtual ports, where each output control works. You can use 4 on / off callbacks (4 for ON, 4 for OFF).
  • One port handles one output that can be controlled by power on / off.
  • Amazon Alexa Dot can search for UDP ports on the network and can also issue commands to control them based on a command from a user in English with the appropriate parameter
  • You need to say: "Alexa, Find devices" to find devices
  •       
  • Alexa answers after a while: "The Discovery is complete, I found one smart device." - this is to verify that the NodeMCU (ESP8266) is visible in the LAN.
  •       
  • Use one of the following demo commands to control the relay: "Alexa, Turn relay one on" , "Alexa, Turn relay one off" and similarly for other outputs
  • Used hardware:

    Amazon Alexa Dot (versions 1 and 2 are compatible) Amazon Alexa Dot
  • ESP8266 / NodeMCU (v1/v2/v3) ESP8266
  • 1+ electromagnetic / SSR channel relay Elmg. relé
  • exploitation:

  • Control the lights and outputs directly from the callback
  • Control other systems (Loxone and others that support HTTP authentication and GET / POST request)
  • Request for web service
  • Libraries: Github
          
  • The ESP8266 sample DEMO programs can control one output according to the voice command above.
  • ESP8266 sketch - NodeMCU + Loxone HTTP request - ON/OFF
