Weather MQTT Support

Application Functionality & Background

Weather MQTT functions as a GUI to any weather station that is running the WeeWX software (http://www.weewx.com) and is also pushing messages to an MQTT server. It connects to the MQTT server (you can find the MQTT extension for WeeWX here: https://github.com/weewx/weewx/wiki/mqtt) and it listens for topic updates and it publishes their values to the GUI.

Setup

Application configuration

In this screen you can setup the following:

• Gauges/screen is the total number of gauges on the screen. (I find that on the iPhone, 3 works best and on an iPad I pick 8)
• The landscape number of gauges X the portrait need to equal the total gauges per screen. (In the below iPhone configurations I have setup 3 gauges per screen, 1 wide by 3 vertical in portrait mode and 3 wide by 1 vertical in landscape mode)
• Station units are the units your weather station MQTT configuration is reporting on so gauge unit conversions can take place
• Host name is the host where your MQTT server is running on
• Port is the port the server is listening on
• Websockets if used can be checked off
• TLS can also be used if your MQTT server is running over HTTPS. (You will need to have setup a valid certificate on the MQTT server)

Adding screens and gauges

In screen maintenance job you can do the following:

• Add any number of screens containing gauges by clicking Add Screen.
• Clicking on the i symbol, allows you to edit the screen name.
• Clicking on edit, allows you to:
  • Select multiple screens to delete.
  • Rearrange screen order.

Adding gauges to a screen

After creating and saving a screen you can select it in order to manage the gauge contents for it

Things you can do:

• Add a number of gauges to your screen.
• Edit, to delete multiple gauges or rearrange their order

Customizing gauges

The gauges are easily customized as follows:

• You can pick the main display units (shown by the gauge needles). The units are predefined.
• You can check the rounding on the units.
• You can set the look for each gauge based on what values are expected.

Below is a depiction of a customization for a Barometer measurement gauge. 

Notice the following:

• The Label non-zero start decides the starting (lowest) value the gauge will show. (Your barometer depending on your location will usually not be under 800 mbar)
• The Label end is added to Label non-zero start, so the highest value the gauge will show is 1080 mbar.
• The Label step indicates how often there will be a numbered label (should coincide with your major ticks frequency). In the below example we have numeric numbered labels every 20 units. 
• Major tick end is the number of major ticks for the gauge. Since the gauge will display from 800 to 1080, which is 280 units, there will be a major tick every 20 units. (280 / 14)
• The Minor tick step is set to 2 which means that there will be (280 / 2) of them on the gauge, and the distance between minor ticks is representing 2 units.
