Configure Alexa to discover RainMachine

- Make sure your RainMachine device has at least firmware version 4.0.631

Note: Alexa will discover as "devices" all your RainMachine programs and zones and use their custom names to address them.

- ERROR - Alexa will respond that the "devices" could not be discovered. Please ensure that your RainMachine is on the same WiFi network as Amazon Echo and Amazon Echo server is enabled under RainMachine settings (see chapter 4).

Voice control your RainMachine

Use voice commands to turn manually ON and OFF a program and an individual zone by calling its own custom name.
Note: For this you can use either "turn" or "switch" as the trigger word.

 
Example: Your RainMachine has one scheduled program with the custom name set by you as: "Flowers" and the Zone 4 is renamed by you as "Tulips"

START voice command

to START the program "Flowers" use the voice command:

"Alexa, turn on program Flowers"
to START the zone "Tulips" use the voice command:

"Alexa, turn on zone Tulips"
Note: Alexa utterance (voice interface) must be used into the voice command. In our case "program" when we want to control (start/stop) a RainMachine scheduled program and "zone" when we want to (start/stop) an individual RainMachine watering zone.

STOP voice command

to STOP the program "Flowers" use the voice command:

"Alexa, turn off program Flowers"
to STOP the zone "Tulips" use the voice command:

"Alexa, turn off zone Tulips"
