\title aWATTar
\brief Plugin for aWATTar, an austrian energy provider.
\ingroup plugins
\ingroup guh-plugins
This plugin allows to receive the current energy market price from the \l{https://www.awattar.com/}{aWATTar GmbH}.
In order to use this plugin you need to enter the access token from your energy provider. You can find more
information about you accesstoken \l{https://www.awattar.com/api-unser-datenfeed}{here}.
\chapter Available data
In following chart you can see an example of the market prices from -12 hours to + 12 hours from the current
time (0).The green line describes the current market price, the red point line describes the average
price of this interval and the red line describes the deviation. If the deviation is positiv, the current
price is above the average, if the deviation is negative, the current price is below the average.
\list
\li -100 % \unicode{0x2192} current price equals lowest price in the interval [-12h < now < + 12h]
\li 0 % \unicode{0x2192} current price equals average price in the interval [-12h < now < + 12h]
\li +100 % \unicode{0x2192} current price equals highest price in the interval [-12h < now < + 12h]
\endlist

\chapter Heat pump
Information about the smart grid modes can be found \l{https://www.waermepumpe.de/sg-ready/}{here}.
In order to interact with the heat pump (SG-ready), this plugin creates a CoAP connection to the server running on the
6LoWPAN bridge. The server IPv6 can be configured in the plugin configuration. Once the connection is established, the
plugin searches for 6LoWPAN neighbors in the network.
\note Currently there should be only one heat pump in the 6LoWPAN network!
\chapter Plugin properties
Following JSON file contains the definition and the description of all available \l{DeviceClass}{DeviceClasses}
and \l{Vendor}{Vendors} of this \l{DevicePlugin}.
For more details how to read this JSON file please check out the documentation for \l{The plugin JSON File}.
