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
- ESP8266 Lolin D1 Mini with Deep-Sleep
- BME280 climate sensor (i2c-Mode)
- 200x200 WeAct EPD/eInk display (4-Wire SPI)
Weather data is presented the following way using the eInk-Display:
The following sensors are automatically discovered by the HA MQTT auto discovery:
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
The KiCad 8.0 project is located in the kicad folder.
