Just share Some Info

if you turn OFF the Arduino ESP
press some buttons in the Home Bot

then Browse to

https//api.telegram.org/botxxxxxmybottokenxxxxx/getUpdates
replace the xxxxxmybottokenxxxx for your bot token
https//api.telegram.org/bot +yourbottoken+ /getUpdates

then you see a list of pending messages

if you turn ON the Arduino ESP messages will be processed
and browser
https//api.telegram.org/bot +yourbottoken+ /getUpdates
will be empty

// GPIO where the Wemos D1 Mini DS18B20 temperature sensor shield is connected
// const int oneWireBus = 4; // d1 mini ESP8266 D2=gpio4

// const int oneWireBus = 35; // 35 not tested waiting for boards lolin mini ESP32S3
const int oneWireBus = 21; // wemos d1 mini esp32

wemos ESP32S3 mini pinout

might be a failure in my code
if your bot is not responding anymore

telegram pending messages are not cleared

browse to

ESP32 ESP32S2 ESP32S3 ?
smaller message keyboard

Changed Again
Any ESP32?
Can run it bare board?!

Changed Again
added FastLed library
for onboard WS2812 LED on ESP32S3

Think the wemos mini DS18B20 temperatur sensor shield
does not work on ESP32S3
Data pin will be on pin 35
wich is a input only pin
DS18B20 needs in/output

if i bring the DS18B20 Wemos mini shield data pin D2 to ESP32S2 GPIO21
Temperature works

#include <OneWire.h>
#include <DallasTemperature.h>

// GPIO where the DS18B20 is connected
const int oneWireBus = 21;

// Setup a oneWire instance to communicate with any OneWire devices
OneWire oneWire(oneWireBus);

// Pass oneWire reference to DallasTemperature library
DallasTemperature sensors(&oneWire);

void setup() {
  Serial.begin(115200);
  sensors.begin(); // Initialize the DallasTemperature library
}

void loop() {
  sensors.requestTemperatures(); // Send the command to get temperatures
  float temperatureC = sensors.getTempCByIndex(0); // Read temperature as Celsius
  Serial.print("Temperature: ");
  Serial.print(temperatureC);
  Serial.println("°C");
  
  delay(2000); // Wait for 2 seconds between measurements
}

settings i used for purple wemos ESP32S3 mini
connect USB powerup with button 0 pressed
when programming finnished button RST reset

ESP32
test no hardcode
AP Access Point configure wifi & bottoken chatid
when connected wifi station sends message to bot

added UpTime
with millis() +/- 49 days rollover count
