 1 | # esphomeweatherstation
 2 | ESPHome based weatherstation station. Hardware from MakerLife Weather Station Kit Pi Zero W. 
 3 | Replaced Raspberry Pi Zero W with ESP8266.
 4 | ESP8266 programmed using https://esphome.io
 5 | 
 6 | - Wind gauge (m/s)
 7 | - Rain gauge (mm rain per minute, mm rain daily)
 8 | - Temperature sensor (degC)
