How to use

Configuration possibilities

configuration of the node

there are 2 lists one for definition of Holidays and one for special days which are not Holidays.

Under the lists are Buttons to fill the lists with pre defined Holidays for German and Austria. If all is selected, all holidays are used (independent if they are really for all regions are available) and id "allgemeine" are used only holidays will be considered which are available in all regions of Germany.

Options for the incoming message object

The incoming message is mainly used for trigger the calculation. This will be done typically once per day. Nevertheless you have the following possibility's to configure the working of the node by the following properties of the incoming messages:

ts, msg.ts defines a timestamp for the source (today) for calculation of the data. if not defined today will be used.
day, msg.day if defined only the Holiday information will get the relative to the timestamp (today by default). So if msg.ts is not defined, msg.day = 0 is today, msg.day = -1 is yesterday; msg.day = 1 is tomorrow, ... Additionally the output will be a day object only representing this day.
date, msg.date if defined only the Holiday information for the defined date will given. If this is given, the output will be only a day object representing this day.
year, msg.year if defined only the Holiday information for the defined year will given. Will only work if no msg.date or msg.ts are in the input message, because otherwise the year information from there will be used.
region, msg.region the region which should be used for getting holidays. If this property is in the input message only the holidays of the region will be considered and nit the setup holidays in the configuration of the node. This property must be a string of two letters with the German state shortcut (BY=Bayern, BE=Berlin, ...).

msg.payload.next.holiday enh-day-object object representing the next holiday.
msg.payload.next.holidays array array of the next 10 holiday (msg.payload.next.holidays.0 is equal to msg.payload.next.holiday), every enh-day-object has additional a diffDays property which is the count of days until this holiday and a diff which represents the difference in milliseconds.
msg.payload.next.holidayDiff number count of days until next holiday.
msg.payload.next.specialday enh-day-object object representing the next special day.
msg.payload.next.specialdays array array of the next 10 special days (msg.payload.next.specialdays.0 is equal to msg.payload.next.specialday), every enh-day-object has additional a diffDays property which is the count of days until this holiday and a diff which represents the difference in milliseconds.

(optional) msg.payload.data any is the same as msg.payload.today.data and only available if additional data is available for today.

Usage

Typically the node will be triggered at once every day and the result will be persistent in a global context. Then with a switch node the flows can be controlled by the usage of the properties of the object output. Examples for using this node:

shutter can be opened/closed on different timestamps based if today or tomorrow is a holiday
dimmer can set to different brightness based if it is a Holiday
