FLProg + TelegramBot + EEPROM + OTA = all works.
The project went to the logical result: now you can use the power of Telegram, the versatility of ESP8266 and the availability of solutions to FLProg !!!
With the help of colleagues, it was possible to solve one problem - the menu of constants. Now you can update the project and configure the settings remotely and on the fly.
You want to change the temperature value for the alert - just point it to the bot from the smartphone.
