## Beschreibung

Show your visitors what electricity costs today, hour by hour, on the Dutch day-
ahead market. The cheapest two-hour block is highlighted, so people with a dynamic
contract, solar panels, a heat pump or an electric car can see when to run the washing
machine or charge the car.

 * **Block:** add „Electricity price today“ in the block editor (category Widgets).
 * **Shortcode:** `[voltij_stroomprijs]`, or `[voltij_stroomprijs theme="dark"]`
   for a dark background.
 * **Widget:** „Electricity price today (Voltij)“ for a sidebar or footer.

The image is updated every night shortly after midnight (Amsterdam time). If today’s
prices are not available yet, the image says so. It never shows an invented number.

The prices are wholesale day-ahead prices for the Netherlands (source: ENTSO-E),
without energy tax, VAT and supplier mark-up.

Good to know:

 * No JavaScript and no cookies on your public site: it is a plain image.
 * Your site does not fetch or store anything; your visitors‘ browsers load the 
   image from voltij.nl.
 * Optionally link the image to voltij.nl, where visitors see all hourly prices 
   of today and tomorrow. This is off by default; switch it on in the block or widget
   settings, or with `link="yes"` in the shortcode.

The plugin interface is in English and can be translated on translate.wordpress.
org.

### External services

This plugin shows an image that is hosted by Voltij (voltij.nl), a free Dutch electricity
price service by Xaven BV.

 * **What:** the image `https://voltij.nl/widget/vandaag.svg` (or `vandaag-donker.
   svg` for the dark version) with today’s hourly electricity prices.
 * **When:** each time a page with the block, shortcode or widget is viewed, and
   in the block editor.
 * **What is sent:** the visitor’s browser requests the image directly from voltij.
   nl. Like any image request, this includes the visitor’s IP address, browser user
   agent and, depending on the browser, the referring page. The plugin itself sends
   no data and sets no cookies. Voltij does not use this request to track visitors.

at most half an hour.

night.
