svitlobot on esp8266-esp32

A few months ago I joined the Svitlobot project. This is a project for monitoring electricity in the house.
I purchased two esp8266 boards and flashed this firmware.
One board works in my apartment, and the second board is installed in the concierge’s room and works on another Internet provider for greater stability.
My version of the firmware allows you to work with the Svitlobot API and Healthchecks.io at the same time.
Therefore, the light bot sends messages to a separate Telegram channel, and the health check sends additional messages to a private group of residents of the house.
Here’s an excellent guide in Ukrainian
