# ESP-SolMon

HomeAssistant integrated Weather station for ESP8266 powered by fadushin/solar-esp32 solar power charge supervisor,

with optional direct to InfluxDB output.

This is a work in progress. This code is meant for a solar power weather station. Mine is built with an ESP-12E module,

but any ESP8266 will work. With very few modifications it should work on and ESP32 as well. The board is powered by a

LiFePo4 battery and an amazing little (1 inch square) open hardware solar charge module that you can build yourself. See 

https://github.com/fadushin/solar-esp32 for more details on the solar charger. I am currently using mine with a very small 

36x68mm solar panel and it keeps the battery near full all the time, and it recovers to a full charge even on cloudy days.

A BME280 is used to collect temperature, air pressure, and humidity. An ADS1115 is used to collect battery and panel

voltage readings from the solar-esp32 module. A 2N2222 transistor is used to cut power to the sensor modules during sleep,

assuring as minimal of a power drain as possible. A lux meter will be added soon. I also have plans to add a rain intensity

sensor and an anemometer.

server addresses, and passwords.
