Sketch isn't looping/Locking up?

I now have it looping, until the mbrVint changes values. It completes the servo move, then freezes. I'm SOOOO close I can smell it!!!

// D0=16, D1=5, D2=4, D3=0, D4=2, D5=14, D6=12, D7=13, D8=15
#include <ThingSpeak.h>
#include <ESP8266WiFi.h>
#include <Servo.h>

const char* ssid          = "NOTYOURS";  
const char* password      = "12345678";
WiFiClient  client;
const unsigned long SampleInterval = 500;


// Master Bedroom Stuff
Servo servo1;
const int servo1Pin           = 13;   //Master Bedroom - D1
const int MBRopenPos          = 0;
const int MBRclosePos         = 180;
unsigned long myChannelNumber = 123456;
const char * myReadAPIKey     = "*************";
String mbrV                   = "";


void MoveTo(int position) {
  static int lastPosition = -1;
  if (position != lastPosition) {  // Position changing
    servo1.attach(servo1Pin, 785, 2180);  // Set limits of pulse width in microseconds
    servo1.write(position);
    delay(1000);  // Give the servo time to move to the new position
    servo1.detach();  // Disconnect servo to reduce currrent load and servo life
    lastPosition = position;
  }
}


void setup() {
  Serial.begin(115200);
  delay(10);
  Serial.print("Connecting to ");
  Serial.println(ssid);

  WiFi.begin(ssid, password);
  int wifi_ctr = 0;
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("WiFi connected");  
  Serial.print("IP Address: ");
  Serial.println(WiFi.localIP());
  ThingSpeak.begin(client);
}


void loop() {
  static unsigned long lastSampleTime = 0;
  unsigned long currentTime = millis();
  if (currentTime - lastSampleTime >= SampleInterval) {
    lastSampleTime = currentTime;
    
    mbrV = ThingSpeak.readFloatField(myChannelNumber, 4, myReadAPIKey);
    int mbrVint = mbrV.toInt();
    
    Serial.print("Master Bedroom Valve Status: ");
    if (mbrVint >= 1) {
      Serial.println("Open");
      MoveTo(MBRopenPos);
    }
    if (mbrVint <= 0) {
      Serial.println("Closed");
      MoveTo(MBRclosePos);
    }

  }
