This is also the 3rd method of finding your client ID Well this program will send you a picture ONLY when you tell it to do that and then the program will just read your chat_id from the incoming message and use that. “Yes, but this program IS supposed to send me something and I clearly see a variable called chat_id, so where do I put mine” I hear you say. Well, remember earlier I said you only needed the chat_id when you wanted to send something from yr micro to your phone? Well, that’s the case right here. When you fill in your WiFi credentials and Telegram API, you may wonder “where the heck goes my chat_id”. So, install the library via library manager and lets have a look at the “PhotoFromURL”example. The “UniversalTelegramBot” is a pretty decent one and the examples should get you up and running fast, even if from first glance it is not always clear what they do □. There are several libraries for Telegram available and you probably already find them in your library manager. If you use a GET URL to connect your ESP to Telegram and you are sure your code is correct, you may have a secure connection problem. ![]() The reason I am not putting a complete and ready “Telegram via GET” program here is because there is actually a pretty decent library program available, so if you insist on using your own GET statements rather than a library, I presume you do that to make very lean code in which case I presume you are versed enough in coding to build your own routine with the help of the above info. In your declaration section you would be stating: WiFiClientSecure botclient String url is the sum of the strings and variables you want to send "User-Agent: BuildFailureDetectorESP8266\r\n" + You would do that with botclient.print(String("GET ") + url + " HTTP/1.1\r\n" + The fact that the API can be reached with a GET message opens up possibilities for an ESP8266, ESP32, Raspberry Pi or other controller that is connected to internet. So now we have our communication with Telegram working, we can go do something useful with it. ![]() There is an other element that can be added at the end and that is &parse_mode=, but for normal operations we can leave that out or make it “&parse_mode=HTML”. Or with a GET URL in a browser like this: You can do that with cURL curl -data chat_id="892915001" -data "text=Hello World" " The id is an integer and it follows a pattern like 123456789 (I will mention a 3rd option further down) Getting your chat ID with IDBot Getting your chat ID with get_id bot The only ones I found working is to the IDBot (and follow the instructions). Getting this ID is not straightforward and most of the methods i have seen on the internet do not work (anymore). You will need this ID to send messages, you do not need it to receive messages. When your bot is created, BotFather gives you the HTTP API token which follows a pattern like 123456789:AABBCCDD_abcdefghijklmnopqrstuvwxyz. ![]() To do this, add BotFather to your contacts or visit /botfather and follow the instructions to create your own bot. Visit Telegram official website and download the official application for your smartphone, or get it from the playstoreĬreate your bot by using a bot called “BotFather”. In order to do so you need to have the telegram app installed, create your own bot to handle the traffic, get an API_key and the chat_id for your bot That means your phone can receive messages sent from your ESP8266 or ESP32, but also that your phone can be used to control your ESP8266 or ESP32. Output Settling Time 4.Telegram is a ‘Whatsapp’ like app for mobile phones to exchange messages.Īn advantage over Whatsapp or Viber is that it also allows you to communicate with your (micro)computer. Typeĭevice provides very high accuracy and low noise performance, and is suitable for consumer and industrial applications, such as set point control, offset adjustment and sensor calibration applications.ġ2-bit Digital-to-Analog Converter MCP4921 Solder PWR SEL SMD jumper to 5V position if used with 5V systems. Board is set to use 3.3V power supply by default. The board provides high accuracy and low noise performance for industrial applications where calibration or compensation of signals, such as temperature, pressure and humidity, are required. It includes a 12-bit Digital-to-Analog Converter MCP4921 that features an optional 2x buffered output and SPI interface.
