# Custom Shelly Pro 2 App

This repository contains a custom app for the Shelly Pro 2. It is based on ESP IDF SDK.

The app uses Wifi, MQTT, OTA and OneWire for DS18B20 sensors. Ethernet via LAN8720 is not implemented because it is currently not required.

## Flashing

:heavy_exclamation_mark: The device ground is wired to the `L` connector, risk of shock due high voltage. :heavy_exclamation_mark:

I recommend to flash the device without power connected by using power supply via flash connector.

At the side of the module is a 7 pin 1.27 mm connector.
