Code

Bylnk + EchoPhotonBridge Libarys

C/C++
In the Future I will add a variety of sensors, and a sleep mode to the Photon to extend the life cycle of the battery. With Particles next release of devices I plan to make a lipo connected solar charged moisture sensor.
I recommend not using digital pin D7.
#define BLYNK_PRINT Serial
#include <blynk.h>
#include <EchoPhotonBridge.h>
EchoPhotonBridge epb;
int functionOnOff(int device, bool onOff, String rawParameters)
{
    digitalWrite(D7, (onOff) ? HIGH : LOW);
}
char auth[] = "Bylnk Auth Token";
void setup() 
{
     pinMode(D7, OUTPUT);
    epb.addEchoDeviceV2OnOff("water", &functionOnOff);
  Serial.begin(9600);
  delay(5000); 
  Blynk.begin(auth);
     
}
void loop() 
{
   Blynk.run(); 
}
