## Crownstone router firmware

Crownstone router firmware runs on the ESP32 microcontroller and delivers device drivers for the Crownstone router, which can be used to improve integration between energy consumers and energy producers.

The firmware is developed using the Zephyr Project.

## Features

- Wi-Fi / Ethernet

- UART (can be used for RS485 and RS232)

- Websocket connectivity / HTTP requests

- Data transport according to own Crownstone router protocol

- Async data sending / receiving using message queues and threads
