Don`t forget to change the sample parameters to the necessary ones. at the file app.js:
#define WIFI_NETWORK "your wifi name"
#define WIFI_PASSWORD "password"
#define HOST_ADDR "hostname.or.address"
#define HOST_PORT 8080 // port number
and look at the end of the file sketch_feb23a.ino:
server.listen(8080, 'some_ip');
and, if you don't use ngrok
applicationId: 'skill_id'
