resiot_gethtml_widget(String, Integer, String, String, String, Bool, String, String, String, String, Integer, Integer, Integer)

Get the HTML code to show a widget based on a Node Field.
Example
resultHTML, err = resiot_gethtml_widget(Reference, WidgetType, AppEUI, DevEUI, Field, CustomSearch, width, height, label, color, hourSel, timeSince, timeTo)
Input Parameters
 - Reference (String): * A unique name you can choose, used to identify widgets, when creating more than one widget per page it is strongly recommended to use different References for each widget.
 - WidgetType (Integer): * A numeric code which identifies the type of widget you want to create. Currently only linear widgets are supported. Linear widget code: 10.
 - AppEUI (String): * The AppEUI of the Node you want to get the Field from.
 - DevEUI (String): * The DevEUI of the Node you want to get the Field from.
 - Field (String): * The name of the Node Field you want to use in the widget.
 - CustomSearch (Bool): * When true it allows to use the custom date filter for the widget, otherwise only default time filters are available.
 - width (String): * The HTML width of the widget, if empty string the width will be set to "100%".
 - height (String): * The HTML height of the widget.
 - label (String): * The label you want to display for the line in the widget.
 - color (String): * The color of the line in the widget.
 - hourSel (Integer): * The default value of the time filter (always expressed in hours). For "Custom" use -1. For "Last values" use -2.
 - timeSince (Integer): * The starting time in Unix of the interval you want to search in. Used only when hourSel is -1 (Custom)
 - timeTo (Integer): * The ending time in Unix of the interval you want to search in. Used only when hourSel is -1 (Custom)
Returns
 - resultHTML (String): * The HTML code of the widget to display.
 - err (String): * The error of the function, if no error this will contain an empty string. *
