# ESP8266 Climate Sensor

[![PlatformIO CI](https://github.com/mirkosertic/ESP8266Weatherstation/actions/workflows/build.yml/badge.svg)](https://github.com/mirkosertic/ESP8266Weatherstation/actions/workflows/build.yml)

This project provides an ESP8266 based climate sensor with the following features:

* MQTT status reporting / remote control

* Home Assistant integration with device autodiscovery

* Multi-Sensor display indoor/outdoor with Weather forecast

* Battery powered with deep sleep support

## Supported hardware

* ESP8266 Lolin D1 Mini with Deep-Sleep

* BME280 climate sensor (i2c-Mode)

* 200x200 WeAct EPD/eInk display (4-Wire SPI)

## Display & HA integration

Weather data is presented the following way using the eInk-Display:

![display](doc/display_example.png)

The following sensors are automatically discovered by the HA MQTT auto discovery:

![haintegration](doc/haintegration.png)

The device collects the following data points:

- Absolute humidity (calculated)

- Relative humidity

- Current battery voltage

- Air pressure

- Temperature

- Overall cycle time of the sensor for one measurement

- Wifi quality

## Schematics & Prototype

The KiCad 8.0 project is located in the kicad folder.
