ESP8266-Weather_station

esp8266, cjmcu8118+hdc1080, bmp180, ccs811, gy30, ssd1306 oled, rotated eeprom, switch interrupt handler, bmp180 custom calibration

Indoor air quality & weather station with Oled display.

Features:

status bar - show datetime and outdoor/indoor temperature;
indoor details frame: indoor sensors readings;
current weather frame: weather icon, weather short description and temperature;
weather forecast frame: forecast for 3 days - day, icon and temperature;
frame autochange;
display sleep timeout;
display on/off by button onSingleClick;
read sensors every second if display.isAwake, otherwise read sensors before uploading data to thingspeak (once in a minute);
store CCS811 baseline into EEPROM (onLongPress) and restore (on boot & after 20 min have passed & manually onPress);
custom calibration for bmp180 temperature sensor to fix factory calibration (or soldering overheating failure) (seek for .ods in project src lib folder)

openweather api: use onecall to fetch forecast instead of 3h forecast api (not optimal) https://github.com/JHershey69/OpenWeatherOneCall/blob/master/src/OpenWeatherOneCall.cpp https://api.openweathermap.org/data/2.5/onecall?lat=57&lon=24.0833&appid=&units=metric&lang=en&exclude=minutely,hourly
- add forecast day/night temperatures
- add more details for current weather data (sun/moon daytime)
recalibrate bsp180 pressure sensor based on outdoor temperature or calculate pressure based on factory calibration...
enter esp8266 powersave mode when switching display off
- where to store data for bulk data upload to thingspeak, i.e. for 10 min instead of 1m?

CCS811 seems to be highly unpredictable...
tocheck# it seems it's a bad idea to train CCS811 baseline outdoors at low temperature for indoor use.
maybe it needs some more time to settle down?
how wrong temperature compensation affects baseline training (and realtime readings)?

Power source can affect CCS811 calculation results as seen below. (~2k variation, 1 reading in 10 sec)

PinButtonEventISR
- static library to use with button interrupts. Handles debounced clicks (single, double, may identify long click too and press*) and hold (short, long) events. (every click and hold starts with press which currently is not identified)
#211230 v1.1.0
- fix gap after dbl click delay and before hold delay occurs
Adafruit_BMP085_Library
- allow to override factory calibration variables, to fix faulty readings (faulty calibration or overheating failure)
- at the same time allow to calculate pressure using factory calibration
- NB temperature compensation works like a charm, however some time needed to be completely sure
CCS811-master
- hide flash methods
esp8266-oled-ssd1306

#211229
- added resetState method to reset timers and move to the first frame
- dont draw abything if display is not awake
#211225
- added isAwake display status flag to avoid rendering when display is off
ClosedCube_HDC1080

#211225
- added begin method that allows to override default resolution parameters
