iobroker.rssfeed v2.8.2

ioBroker Adapter to request and show RSS Feeds of different standards (Atom, RSS, RDF)

Overview

Adapter to request and show RSS Feeds of different standards (Atom, RSS, RDF). You can customize the output of the feed with a template system. In the templates you can include HTML, CSS and Javascript.

Important: Only the english translation is valid due to bugs in automatic translations into other languages made by iobroker

Add an Instance

After Installation the adapter should then be displayed in the adapter section in the iobroker. Sometimes it happens that the changes are not visible, especially with web changes (widgets / configuration dialog), the following command may have to be executed on the command line:

iobroker upload rssfeed

In the right area in the line of the adapter, an instance can be added using the plus button

Configuration

The configuration is easy. There are only a few fields

Then for each new feed:

If you saved and closed the configuration, the feed-data can be found as a JSON data point in the object tree. If you delete an entry, the datapoints aren't deleted.

vis and widgets

The following widgets actually exists

• RSS Feed widget 2 - to show a single feed
• RSS Feed Multi widget - to show several aggregated feeds in one widget.
• RSS Feed Meta Helper - a helper widget to inspect the metadata of a feed
• RSS Feed Article Helper 2 - a helper widget to inspect the article data of a feed
• RSS Feed Title marquee 3 - a widget to show the Headlines of a feed as a marquee
• JSON Template - a widget that have nothing todo with RSS Feeds, but uses the same technology, and you can define a custom template to show any JSON-Data in vis.

Documentation for the vis-widgets are available inside vis or Widget-Documentation/german

Template based on examples

An example that I have tested with the following RSS feeds:

• http://www.tagesschau.de/xml/rss2
• https://www.bild.de/rssfeeds/rss3-20745882,feed=alles.bild.html

<%= meta.title %> 
<% articles.forEach(function(item){ %>
<p><small><%- vis.formatDate(item.pubdate, "TT.MM.JJJJ SS:mm") %></small></p>
<h3><%- item.title %></h3>
<p><%- item.description %></p>
<div style="clear:both;" />
<% }); %>

The template system works with certain tags. The tags used mean the following

Everything that is outside of these tags is displayed exactly as it is or if it is HTML interpreted as HTML. (see e.g. the p-tag, div-tag, small-tag Within the template you have 2 predefined variables available

meta

This contains all meta information about the feed. The following content is available. I think the identifiers are self-explanatory. In the help I will describe them in more detail. or specify the content (some are arrays)

• meta.title
• meta.description
• meta.link
• meta.xmlurl
• meta.date
• meta.pubdate
• meta.author
• meta.language
• meta.image
• meta.favicon
• meta.copyright
• meta.generator
• meta.categories

articles

Is an array with individual elements (javascript array). Each element has the following properties. So that it fits, for example, I will do the prefix item in front of it. But if you want you can choose that yourself. It only has to be named accordingly in the loop (forEach). Here, too, the identifiers are self-explanatory. Not all attributes are filled in every feed. The most important ones are already included in the template above.

• item.title
• item.description
• item.summary
• item.link
• item.origlink
• item.permalink
• item.date
• item.pubdate
• item.author
• item.guid
• item.comments
• item.image
• item.categories
• item.source
• item.enclosures

Template example and detailed description

<%= meta.title %> 
<% articles.forEach(function(item){ %>
<p><small><%- vis.formatDate(item.pubdate, "TT.MM.JJJJ SS:mm") %></small></p>
<h3><%- item.title %></h3>
<p><%- item.description %></p>
<div style="clear:both;" />
<% }); %>

Brief description of what happens in the individual lines
Z1: The output of the feed title
Z2: Without output. Javascript command to loop over all articles, with each turn the current element is assigned to the variable item.
Z3: Output of date and time is. It is enclosed with a p / small tag for formatting. The vis-own date format function is used for formatting. Description can be found in the adapter vis.
Z4: The output of the article title. A Header 3 - tag is used for formatting.
Z5: Output of the content of the article. It is enclosed with a p-tag. Here, at least in the two examples, HTML code is included, which usually comes with an image and descriptive text
Z6: Output a div tag that clears special formatting in the feed-html (in both examples for tagesschau and bild it is needed. Other feed maybe didn't need it.
Z7: Without output. This line closed the javascript loop . Everything that was defined between Z2 and Z7 is repeated for every single article.
