Arduino Core & ESP-IDF implementations. For ESP32 available also with FreeRTOS. ESP8266 and ESP32 support for Ultra Low Power deep sleep app. ESP32 available with PHY Ethernet LAN8…
Library for sending notifications to Telegram from a device to ESP32. There is a built-in queue of outgoing messages for delayed sending (for example, when there is no Internet)
This is an advanced template for the Espressif IDF. This project demonstrates important techniques for large scale IDF development. This project is compiled on the ESP-IDFv5.2.
Sending sensor data to http://open-monitoring.online/ with a specified interval and sending queue. For ESP32 only, since it was released as a FreeRTOS task and on ESP32-specific functions. Controller field values (data) are passed to the queue as a string (char*), which is automatically deleted after sending. That is, to send, you must place a l…
