/* Open Weather - the open source weatherbeacon that also looks good.
We connect to your home wifi and send a http request to open weathermap every hour to update the free 3 hour forecast.
depending on the weather-id (https://openweathermap.org/weather-conditions#Weather-Condition-Codes-2) another led will light up
in a predefined colour to resemble weather and temperature and hightlight the respective icon.
See Full documentation on https://daniel-strohbach.de/diy-esp8266-wetterstation
Parts needed:
- ESP8266 or ESP32 Board, alternatively arduino nano with wifi shield will do as well but not coded here
- Optional: DHT22 or DHT11 Sensor to measure Indoor Temp and Humidity
- 4x WS2812 (aka NeoPixel) LED
Solder the 4 LEDs into a tiny LED Strip and connect to Dev Board:
Board LED LED LED LED
3V3 - VCC - VCC - VCC - VCC
GND - GND - GND - GND - GND
D8 - I/0 - I/O - I/O - I
Connect DHT22 / DHT11 to
Board DHT
3V3 - +
GND - -
D4 - OUT
Pixel-ID Icon reference (take care when assembling or switch in the code
0 - clear sky
1 - cloudy
2 - rainy
3 - snow
Outdoortemperature & Colours:
> 30°C - Red
> 21°C - Warm yellow
< 18°C - Light blue
< 00°C - Blue
Thunderstorm: Yellow
Fog: White
Red: Wifi related error
green: connecting
Optional: Send the measured DHT Data to an MQTT Broker (topics are customizable within captive portal)
receive Data:
temperature: stat/openWeather/Temperatur
Humidity: stat/openWeather/Feuchtigkeit
HeatIndex: stat/openWeather/HeatIndex
control openWeather:
light on: cmnd/openWeather/power - payload on
light off: cmnd/openWeather/power - payload off
switch to party mode: cmnd/openWeather/state - PixelParty1 or PixelParty2
upon receiving a command it sends back on stat/openWeather/power and stat/openWeather/state which mode it is in.
Dependencies:
PubSubClient
ArduinoJson
ESP8266 Libs
ESP32 Libs
DHT Sensor library for ESPx
WifiManager
LittleFS
Now with Wifi Manager or HardCoded Wifi credentials optional.
Thanks to https://github.com/CurlyWurly-1/ESP8266-WIFIMANAGER-MQTT/blob/master/MQTT_with_WiFiManager.ino
Now with OTA Update via ArduinoOTA
