I am having similar problem using the ESP8266 boards, I think the BlynkSimple library has a bug that causes the WDT timer to reset
other iot platforms that do not use the Blynk library work OK
I hope it gets fixed when Cayenne supports the ESP8266 officially.

The Esp8266 is working for me-
I’m using an Esp12-e, and the Arduino IDE.
I put the ESP into “program” mode by
shorting GPIO 0 to ground for 20 seconds while booting.
Then you can upload your arduino code-
This code works for me-
the rest of the programming is done
from the App or the Cayenne HTML page.

 //#define CAYENNE_DEBUG         // Uncomment to show debug messages
#define CAYENNE_PRINT Serial  // Comment this out to disable prints and save space
#include "CayenneDefines.h"
#include "BlynkSimpleEsp8266.h"
#include "CayenneWiFiClient.h"

// Cayenne authentication token. This should be obtained from the Cayenne Dashboard.
char token[] = "YourToken";
// Your network name and password.
char ssid[] = "YourSSID";
char password[] = "YourPassword";

void setup()
{
  Serial.begin(9600);
  Cayenne.begin(token, ssid, password);
}

void loop()
{
  Cayenne.run();
}

I don’t see any resets in his screen shot there. I think this may be another issue such as 2.4GHz interference (or too far from access point) or low quality WAN causing disconnects.
