Open Source C++ Telegram Bots

Application for ESP32 / ESP32S3 with OV2640 / OV5640 camera to record JPEGs to SD card as AVI files and playback to the browser as an MJPEG stream. The AVI format allows recordings to replay at the correct frame rate on media players. If a microphone is installed then a WAV file is also created and stored in the AVI file. The ESP32 cannot support all of the features as it will run out of heap space. For better functionality and performance, use one of the new ESP32S3 camera boards, eg Freenove ESP32S3 Cam, and ESP32S3 XIAO Sense, but avoid no-name boards marked ESPS3 RE:1.0.

C++ library for Telegram bot API.

This library directly interfaces Arduino, esp8266, esp32, and esp32-s2 microcontrollers to DSC PowerSeries and Classic series security systems for integration with home automation, remote control as a virtual keypad, notifications on alarm events, unlocking installer codes, and emulating DSC panels to use DSC keypads as general purpose input devices. This enables existing DSC security system installations to retain the features and reliability of a hardwired system while integrating with modern devices and software for under $5USD in components.
