Customization based on SwitcDoc Labs GroveWeatherPi components.

Objective: Simplify and published near realtime weather sensor data via MQTT.

Instructions:

1. Follow the original SwithcDoc instructions (below) and enable the components you are using in config.py
2. Add your MQTT broker IP and credentials in wxmqtt.py
3. Start with: sudo python wxmqtt.py

Test by using a MQTT client like MQTT Explorer https://github.com/thomasnordquist/MQTT-Explorer.git

Message queues are:

wx/totalRain" wx/currentWindSpeed" wx/currentWindGust" wx/currentWindDirection" wx/currentWindDirectionVoltage"

To do: Move MQTT Broker setup to config.py Add more sensors Add MQTT LWT

Weather Board Libraries and Example for Raspberry Pi

Supports SwitchDoc Labs WeatherRack / Argent Data / Sparkfun

Version 1.8

August 22, 2016: Added support for WXLink - Wireless connection to WeatherRack and AM2315

August 4, 2016: Fix for OLED Present under Lightning Conditions

SwitchDocLabs Documentation for the Weather Board under products on:

http://www.switchdoc.com/

Support for all 7 I2C devices supported by the Weather Board

New Support for the SwitchDoc Labs Grove OLED Board
New Support for the ThunderBoard Lighting Detector
New Support for SwitchDoc SunAirPlus Solar Power Controller Board

Other installations required for AM2315 support:

sudo apt-get install python-pip
sudo apt-get install libi2c-dev
sudo pip install tentacle_pi

Other installations required for SD1306 OLED support: sudo apt-get update

sudo apt-get install python-imaging python-smbus

sudo apt-get install build-essential python-dev python-pip
sudo pip install RPi.GPIO

Finally, on the Raspberry Pi install the Python Imaging Library and smbus library by executing:

sudo apt-get install python-imaging python-smbus

Now to download and install the SSD1306 python library code and examples, execute the following commands:

sudo apt-get install git
git clone https://github.com/adafruit/Adafruit_Python_SSD1306.git
cd Adafruit_Python_SSD1306
sudo python setup.py install

Modify this section of code to support your configuration:

# set to true if you are building the Weather Board project with Lightning Sensor
config.Lightning_Mode = False
# set to true if you are building the Solar Powered Weather Board
config.SolarPower_Mode = False

All other devices are detected automatically.

sudo python WeatherBoard.py

If you attach an AM2315 to the WXLink Transmitter, then the program will assume that is the AM2315 you want for outside temperature and humidity. These values will overwrite the AM2315 connected to the local Raspberry Pi or Weather Board.
