<p>A node which polls a server for current weather data when an input is received.</p>
74+
75+
<p> This is done using either:</p>
76+
<ul>
77+
<li> a city and the country in which that city lies</li>
78+
<li> a latitude and longitude set of coordinates </li>
79+
</ul>
80+
<p>These can be passed in as settings on the node, or as the:</p>
81+
<ul>
82+
<li> <b>msg.payload.lat</b> and <b>msg.payload.lon</b>, or </li>
83+
<li> <b>msg.payload.city</b> and <b>msg.payload.country</b> </li>
84+
</ul>
85+
<p>of the message input. </p>
86+
<p>The node will always prioritise the parameters passed in when both of <b>lat/lon</b> or <b>country/city</b> are present.</p>
87+
88+
<p>The node sets the following properties of <b>msg.payload</b>:</p>

<li><b>description</b> - a brief verbal description of the current weather for human reading.</li><br>
91+
<li><b>weather</b> - a short description of the current weather.</li><br>
92+
<li><b>detail</b> - a more detailed expansion on <b>weather</b>.</li><br>
93+
<li><b>tempk</b> - the current gorund temperature at that location in Kelvin.</li><br>
94+
<li><b>humidity</b> - the current humidity at the location in percent.</li><br>
95+
<li><b>maxtemp</b> - the current maximum temperature at the location in Kelvin.</li><br>
96+
<li><b>mintemp</b> - the current minimum temperature at the location in Kelvin.</li><br>
97+
<li><b>windspeed</b> - the current wind speed at the location in Metres per second.</li><br>
98+
<li><b>winddirection</b> - the current wind direction at the location in meteorological degrees.</li><br>
99+
<li><b>town</b> - the name of the location from which the data was sourced.</li><br>
100+
<li><b>lon</b> - the longitude of the location from which the data was sourced.</li><br>
101+
<li><b>lat</b> - to the latitude of the location from which the data was sourced.</li><br>
102+
<li><b>sunrise</b> - the time at which the sun rose in Unix UTC format.</li><br>
103+
<li><b>sunset</b> - the time at which the sun will set in Unix UTC format.</li><br>
