Hi Sara,
this beautyful program does not work since ArduinoJson was updated to V.7.0.0. Restoring the last v.6.x.x solves the problem.

Hi.
You just need to add a new timer to your code

const unsigned long messageInterval = 180000; //This is half an hour
unsigned long lastMessageTime = 0;

Then, add something like this to the loop() – i haven’t tested it, but the logic is this:

void loop() {
unsigned long currentTime = millis();

if (currentTime – lastMessageTime >= messageInterval) {
String readings = getReadings();
bot.sendMessage(CHAT_ID, readings, “”);
lastMessageTime = currentTime;
}

I hope this helps.
Regards,
Sara

Hello. Tell me, please, is there any command that allows you to take readings from the sensor every half hour and the bot sends messages?

Hi.
If nothing happens, it may probably be related to the chat ID or the API Token.
Additionally, make sure you’re sending the telegram messages to the right BOT.

Hi Sara,
I followed in a meticulous way your clear instructions and I copied your code but when I run the code it just stops after printing in the serial monitor
Connecting to WiFi.. and the IP address
and when I access Telegram after /start and/readings nothing happens
I verified several times both the CHAT_ID and the API_TOKEN but they are correct
Could you help me ? Thanks
Bruno

Good morning Sara,
I have a doubt about reading the temperature via telegram with ESP32 and DHT22.
How can I configure the reading with only one decimal digit?
With the print on the led display it’s easy but with telegram I didn’t succeed.
Thank you
giuseppe

Hi.
Try using the AsyncTelegram library: https://github.com/cotestatnt/AsyncTelegram
