My ethernet gateway died and I made another one on a Raspberry Pi so I updated all of my sensors from 1.4 libraries to 2.2. Here's the updated sketch for these servo blind control nodes:
// A sketch to control a servo with a button and MySensors messages
//#define MY_DEBUG
// Enable and select radio type attached
#define MY_RADIO_NRF24
//#define MY_RADIO_RFM69
#include <SPI.h>
#include <MySensors.h>
#include <Servo.h>
#include <Button.h> //https://github.com/JChristensen/Button
#define BUTTON_PIN 4 //Connect a tactile button switch (or something similar)
//from Arduino pin 4 to ground.
#define PULLUP true //To keep things simple, we use the Arduino's internal pullup resistor.
#define INVERT true //Since the pullup resistor will keep the pin high unless the
//switch is closed, this is negative logic, i.e. a high state
//means the button is NOT pressed. (Assuming a normally open switch.)
#define DEBOUNCE_MS 20 //A debounce time of 20 milliseconds usually works well for tactile button switches.
#define LONG_PRESS_PERIOD 700 //How long to keep button pressed until sweeping starts
#define MAX_DEGREES 180 //Servo limits. Whatever works for you.
#define MIN_DEGREES 0
#define CHILD_ID 3
Button myBtn(BUTTON_PIN, PULLUP, INVERT, DEBOUNCE_MS); //Declare the button
Servo myservo;
enum {DECREASING, INCREASING}; //On a servo mounted on the left, with outer slat edge down as closed,
// closing is going toward 180, opening toward 0 (on my fake futaba s3003's)
boolean invertConversions = true; // false if opening toward 180
boolean servoDirection = INCREASING; //A variable that keeps the current servo direction
int servoPin = 3;
int servoPosition;
int servoSpeed = 1; // The bigger, the faster. 1=slow 5=fast

// Register all sensors to gw (they will be created as child devices)

myBtn.read(); //Read the button
if (myBtn.wasReleased()){ //If the button was pressed once sweep to end of current direction

send(msg.set(ConvertDegToPercent(servoPosition)));
