Belchertown weewx skin

This skin (or theme, or template) is for the weewx weather software and is modeled after my website BelchertownWeather.com. I developed that website with custom features but used weewx as the backend archive. It was a good fit to port the site to a weewx skin.

BelchertownWeather.com Homepage

Features include:

  • Real-time streaming updates on the front page of the webpage without neededing to reload the website. (weewx-mqtt extension required)
  • Forecast data updated every hour without needing to reload the website. (a free DarkSky API key required)
  • Information on your closest Earthquake updated automatically every 3 hours
  • Observation graphs without needing to reload the website.
  • Weather records for the current year, and for all time.
  • Responsive design. Mobile and iPad landscape ready! Use your mobile phone or iPad in landscape mode as an additional live console display.

Requirements

weewx.conf

These settings need to be enabled in order for the skin to work. Within weewx.conf, under [Station] make sure you have:

  • latitude - used for forecasting and earthquake data
  • longitude - used for forecasting and earthquake data

You need to define your URL for the skin to work properly. The full URL to your website without a trailing slash. Example: http://yourwebsite.com or http://192.168.1.100. Even if your website is on your LAN only, this needs to be enabled. There are 2 ways to do this which offer flexibility. See below General Options for more information. You need to only enable 1 option for the skin to work.

  • belchertown_root_url - This is the preferred option. Add this to your skin Extras section (see below).
  • station_url - This is the built-in weewx.conf config.

DarkSky API (optional)

DarkSky API is where the forecast data comes from. The skin will work without DarkSky's integration, however it is used to show current weather observations and icons.

You must sign up to use their service. This skin does not provide any forecast data. You need to join their website and get a free developer key. Their free tier allows for 1,000 requests a day. The skin will download and cache every hour - 24 requests a day - well below the free 1,000.

  • Sign up at https://darksky.net/dev
  • Once you are logged in, take note of the Secret Key on the DarkSky console.
  • Use this key as the darksky_secret_key option. See below options table after you have installed the skin.
  • Make sure you place the "Powered by DarkSky" somewhere on your website. Like the About page (see below after install for customizing the About page).

MQTT (optional)

MQTT is a publish / subscribe system. Mostly used for IoT devices, but it works great for a live website.

You will to use an MQTT broker (aka server) to publish your data to. You can install your own broker pretty easily, or use a public one (some free, some paid). Your weewx server will publish it's weather data to a broker and visitors to your website will subscribe to those updates using MQTT Websockets. When data is published the subscribers get that data immediatly.

With the weewx-mqtt extension installed, everytime weewx generates a LOOP it'll automatically publish that data to MQTT which will update your website in real time. Once ARCHIVE is published, your website will reload the forecast data, earthquake data and graphs automatically.

A sample MQTT extension config is below. Update the server_url, topic, and unit_system to suite your needs. Keep binding as archive and loop. Remove the tls section if your broker is not using SSL/TLS.

    [[MQTT]]
        server_url = mqtt://username:password@mqtt.hostname:port/
        topic = the/topic/to/publish/to
        unit_system = US
        binding = archive, loop
        aggregation = aggregate
        [[[tls]]]
            tls_version = tlsv1
            ca_certs = /etc/ssl/certs/ca-certificates.crt

I did not write the MQTT extension, so please direct any questions or problems about it to the user forums.

MQTT Websockets (optional, but required if you want real-time updates)

Your MQTT broker (server) will need to support MQTT websockets in order for the website skin to connect to the MQTT topics. Please make sure your broker has websockets support.

MQTT Brokers

Install your own MQTT Broker

If you want to run your own MQTT broker, you can follow these instructions that I've put together.

Use a Public Broker

These public brokers have been tested as working. If you have others to add the to the list, let me know.

Install weewx-belchertown

  1. Download the tar gz file.

  2. Run the installer. Replace x.x with the version number of the skin you've downloaded.

sudo wee_extension --install weewx-belchertown-x.x.tar.gz
  1. Restart weewx:
sudo /etc/init.d/weewx stop
sudo /etc/init.d/weewx start
  1. Wait for an archive period, or run sudo wee_reports to force an update

  2. Browse to your website to see the skin. It may be in the belchertown subdirectory.

Belchertown Skin as Default Skin

To make Belchertown the default skin for your site, make the configuration changes as below. This is an example config and may need a little fine-tuning site-per-site.

  1. In weewx.conf look for the [StdReport] section. Within that section is [[StandardReport]] and under that change skin = Standard to skin = Belchertown.

  2. Take note of the HTML_ROOT setting in the [StdReport] section since you will need it for the next section.

  3. Then modify the Belchertown skin options with these minimal updates:

    [[Belchertown]]
        HTML_ROOT = <<the HTML_ROOT location as above. E.g. public_html>>
        skin = Belchertown
        [[[Extras]]]
           belchertown_root_url = "http://your_full_website_url"
           
   [[Highcharts_Belchertown]]
        HTML_ROOT = <<the HTML_ROOT location as above. E.g. public_html>>
        skin = Highcharts_Belchertown
  1. This is optional, but advised: Delete all contents of the HTML_ROOT folder and let Belchertown create an entire new site. This prevents stale duplicate data.

  2. Restart weewx and let it generate the files upon the next archive interval.

Creating About Page and Records Page

The About Page and Records Page offer some areas for custom HTML to be run. To create or edit these pages, go to the skins/Belchertown folder. These files should not be overwritten during skin upgrdades, but it's always best to have a backup just in case!

  • Create (or edit) the skins/Belchertown/about.inc and skins/Belchertown/records.inc files with your text editor, such as Notepad or Nano.
    • These files take full HTML, so you can get fancy if you want.
    • You can view, and use the sample file about.inc.example and records.inc.example. Just rename to remove the .example, edit and you should be good to go.
  • Then restart weewx for the changes to take effect, and wait for an archive interval for the pages to be generated.

Using Metric

If your weewx and your weather station are configured for metric, you can display the metric values in the skin. Just like with the Standard weewx skin, to change the site to metric you would need to add [[[Units]]] and [[[[Groups]]]] to the Belchertown skin options in weewx.conf, with the appropriate group values. Restart weewx when you have made the changes. For example:

[StdReport]
    [[Belchertown]]
        skin = Belchertown
        HTML_ROOT = belchertown
        [[[Units]]]
            [[[[Groups]]]]
                group_altitude = meter
                group_degree_day = degree_C_day
                group_pressure = mbar
                group_rain = mm
                group_rainrate = mm_per_hour
                group_speed = meter_per_second
                group_speed2 = meter_per_second2
                group_temperature = degree_C
    [[Highcharts_Belchertown]]
        skin = Highcharts_Belchertown
        HTML_ROOT = belchertown
        [[[Units]]]
            [[[[Groups]]]]
                group_altitude = meter
                group_degree_day = degree_C_day
                group_pressure = mbar
                group_rain = mm
                group_rainrate = mm_per_hour
                group_speed = meter_per_second
                group_speed2 = meter_per_second2
                group_temperature = degree_C                

Belchertown Skin Options

The Belchertown skin will work as a very basic skin once installed using the default values in the table below.

To override a default setting add the setting name and value to the Extras section for the skin by opening weewx.conf and look for [StdReport]. Under will be [[Belchertown]]. Add [[[Extras]]] (with 3 brackets) and then add your values. For example:

[StdReport]
    [[Belchertown]]
        skin = Belchertown
        HTML_ROOT = belchertown
        [[[Extras]]]
            belchertown_root_url = "https://belchertownweather.com"
            logo_image = "https://belchertownweather.com/images/content/btownwx-logo-slim.png"
            footer_copyright_text = "BelchertownWeather.com"
            forecast_enabled = 1
            darksky_secret_key = "your_key"
            earthquake_enabled = 1
            twitter_enabled = 1
            twitter_owner = PatOBrienPhoto

The benefit to adding these values to weewx.conf is that they persist after skin upgrades, whereas skin.conf could get replaced on skin upgrades. Always have a backup of weewx.conf and skin.conf just in case!

Restart weewx once you add your custom options and wait for an archive period to see the results.

For ease of readability I have broken them out into separate tables. However you just add the overrides to the config just like the example above.

Add Custom Content to the Front Page

There are 4 locations on the front page where you can add your own content. Full HTML is supported. To add content, create a new file in skins/Belchertown with the naming convention below. Restart weewx and wait for an archive period for the content to update.

  • Below the station info: skins/Belchertown/index_hook_after_station_info.inc
  • Below the forecast: skins/Belchertown/index_hook_after_forecast.inc
  • Below the records snapshot: skins/Belchertown/index_hook_after_snapshot.inc
  • Below the charts: skins/belchertown/index_hook_after_charts.inc

Belchertown Skin Custom Content

Change (or remove) a Chart

You can change the order of your graphs by changing the chart plot name by using the options below in your Extras section. See below in General Options. For example if you wanted chart 6 to be humidity, you set highcharts_graph_6 = "humidityplot".

If you want to remove a chart, just specify "". For example to remove chart 6, you would set highcharts_graph_6 = "". Restart weewx when done.

There are 7 chart plots you can use and they are case sensitive - must be lower case.

  • temperatureplot
  • windplot
  • rainplot
  • winddirplot
  • barometerplot
  • radiationplot
  • humidityplot

Here are the default order of the chart plots:

    highcharts_graph_1 = "temperatureplot"
    highcharts_graph_2 = "windplot"
    highcharts_graph_3 = "rainplot"
    highcharts_graph_4 = "winddirplot"
    highcharts_graph_5 = "barometerplot"
    highcharts_graph_6 = "radiationplot"

Frequently Asked Questions

  • Q: I don't have a radiation sensor, can I turn that chart off?
  • A: You can change the chart to something else, like humidityplot. Check these instructions, and restart weewx once you've made the change.


  • Q: My NOAA reports are blank.
  • A: If this is right after you installed the skin, give weewx an archive interval or populate this data

  • Q: I see errors like these:
    • No such file or directory '/home/weewx/skins/Belchertown/about.inc'
    • No such file or directory '/home/weewx/skins/Belchertown/records.inc'
  • A: You probably skipped the step Creating About Page and Records Page. Please give that a try.

  • Q: Do I have to use MQTT?
  • A: Nope! If you disable the MQTT option, then weewx will still create a website for you, it just will be done on the archive interval. weewx will still generate these pages for you if you have MQTT enabled, the benefit is that you do not have to reload the website.


  • Q: Do I have to use forecasts?
  • A: You do not need to use forecasts, but it is recommended to use forecasts so you take advantage of the theme's design with icons and observations.

  • Q: Do I have to use earthquake data?
  • A: Nope! If you leave it disabled, it won't show on the site nor will any data be downloaded.

  • Q: Do I have to use the radar?
  • A: Nope! If you leave it disabled you'll just have a big blank box on the website. But windy.com provides a free animated radar, so why not include it? :)

  • Q: Do I have to use the graphs?
  • A: Nope! If you have it disabled we will hide those portions of the site. It comes packaged with this theme already though, so you can leave it enabled.

  • Q: Why does the skin take a while to generate sometimes?
  • A: This is because of the graph system. That file goes through your archive's day, week, month and year values, and all time values to generate the graphs. Depending on how big your database is this could take a little longer.

  • Q: I noticed my graphs don't update right away on an archive period. How come?
  • A: Because the highcharts can take a few extra seconds, I've put in a 30 second delay on the graphs automatic update. This way it's loading the newest data.

  • Q: Do the graphs on the Graphs page update automatically?
  • A: No, only the front page is automatically updated. All the other pages are normal pages that need to be refreshed to see new information.

  • Q: How do I change my about page, or records page?
  • A: See above on how to do that.

  • Q: How can I tell if the skin downloaded new forecast or earthquake data?
  • A: Check your system log file. You should see the skin output something along the lines of "New forecast file downloaded" or "New earthquake file downloaded".

  • Q: How come I'm seeing NAN in some areas?
  • A: This is because weewx hasn't gathered enough data from your station yet. Give it a few more archive intervals.

  • Q: I'm seeing cheetahgenerator: **** Reason: could not convert string to float: N/A, how do I fix this?
  • A: Upgrade to 0.8.1 or newer which resolves this error

  • Q: How do I uninstall this skin?
  • A: sudo wee_extension --uninstall Belchertown
