Dashboard Widget very slow responsive

Hi all, I am trying to read DHT22 sensor data and activate LED through on/off button.
My hardware configuration is using arduino mega + esp 8266 though GSMlibrary using AT commands.
I find that sometimes the value widget display my sensor value and sometime don’t. This is the same for the button widget and I can’t figure out why. I tried to make my loop function as simple as possible and change my wifi connection to use my phone hotspot, still the same.

This is my code
#define DEBUG
#include <ThingerESP8266AT.h>
#include <ESP8266_Lib.h>
#include <DHT.h>

#define DHTPIN A0
#define DHTTYPE DHT22
#define USERNAME "wxin"
#define DEVICE_ID "humidity"
#define DEVICE_CREDENTIAL "humid7"

#define SSID "Realme C1"
#define SSID_PASSWORD "12345678"

DHT dht(DHTPIN,DHTTYPE);

// Emulate Serial1 on pins 10/11 if HW is not present (use interrupt pins for better performance)
#ifndef HAVE_HWSERIAL1
#define EspSerial Serial1
#endif

ThingerESP8266AT thing(USERNAME, DEVICE_ID, DEVICE_CREDENTIAL, Serial1);

void setup() {
  Serial.begin(9600);
  Serial1.begin(9600);
  dht.begin();

  thing.add_wifi(SSID, SSID_PASSWORD);

  // digital pin control example (i.e. turning on/off a light, a relay, configuring a parameter, etc)
  pinMode(40, OUTPUT);
  thing["LED"] << digitalPin(40);
  
  // resource output example (i.e. reading a sensor value)
  thing["humidity"] >> outputValue(dht.readTemperature());
  //thing["millis"] >> [](pson& out){ out = millis(); };
}

void loop() {
  thing.handle();
}

This is my simple dashboard with widget.

hello @hope_estheim,

If you require speed in your project, I strongly recommend including the Thinger.io client in the ESP8266 instead of using the AT commands. Note that the ESP has a much better processor than the mega and it is optimized for this work.
