node-red-contrib-sun-position
Advanced tools
This is a ultimate Node-Red Timer based flow control with dusk, dawn (and variations) and much more. Additional you can get sun and moon position or to control a flow by sun or moon position. It is ideal for usage of control smart home, but also for all other time based flow control. In addition, there is now a blind controller, which can set blind position time and sun controlled. ( see blind-control )
These nodes need at least Node-Red with Version 0.18! Any early Version of Node-Red will not work!
npm install node-red-contrib-sun-position
The nodes are designed to do not calculate time events with every arriving message or with an interval every x time. This is to be able to handle a huge amount of messages also on even on computers with low resources.
The nodes are designed to be accurate to seconds. This means it was designed to turn on/off at exact given second. Other timers often work using intervals where they check your schedule only once a minute or even less. This means when you want something to come on at 08:00am, it may actually not come on until 30 seconds later. This nodes does not have this problem, it will come on at exactly 08:00:00am.
The node calculates the current sun position on any input message. This node is compatible to node-red-contrib-blindcontroller.

Position connects to the central configuration node, which contains the current position, but also handles internal shared functions
Payload defines the payload of the message object send to the output
Topic defines the topic of the send message
Time An optional property that can be configured when the inject node should emit a message on that timestamp.
Offset An optional property which is only available if an time is chosen. The offset can be a positive or negative and defines a time offset to the chosen time.
Days An optional property which is only available if an time is chosen. There can be defined on which days a msg should be emitted.
Property optional here can be defined a condition under which a alternate time should be used.
Alternate time optional defines an alternate start time which will be used if the condition applies. This can be used for different times for example of holidays/weekend.
Additional Inject on Start If this checkbox is set the inject node can emit the message on Node-Red Start or on any deploy of this node. There can be defined a delay after the emit should be done. This can be useful for initializing any flow.
Set additional With this selection you can

If this checkbox is set the inject node
It has only a button as input, where the massage could injected into a flow manually.
The output is a message with the defined payload and topic in the settings.

Position connects to the central configuration node, which contains the current position, but also handles internal shared functions
Start time defines the start time of the time range with with different configuration possibilities
End time defines the end time of the time range with with different configuration possibilities
Alternate start time optional defines an alternate start time of the time range which will be used if the conditions matches. This can be used for different times for example of holidays.
Alternate end time optional defines an alternate end time of the time range which will be used if the conditions matches. This can be used for different times for example of holidays.
resend start If this checkbox is checked and a message arrived outside of time, this message will be additional send again some milliseconds after next start time point. This option is only for fixed time definitions available.

SunBH is the angle of the sun below the horizon
Although the blue hour does not have an official definition, the blue color spectrum is most prominent when the Sun is between 4° and 8° below the horizon.
This is not an official definition, this is happend when the Sun is 15° below the horizon

String as one of the following formats:
00:00 ... 23:59 24h Format00:00:00 ... 23:59:00 24h Format with seconds00:00pm ... 12:59pm 12h Format00:00:00pm ... 12:59:00pm 12h Format with secondsOffsets: The start and end time can have an offset. This is specified in seconds,minutes or hours:
Some nodes has the ability to get an input time out of different pre defined formats or a free format definition.
The formats are:
| Field | Full Form | Short Form |
|---|---|---|
| Year | yyyy (4 digits) | yy (2 digits), y (2 or 4 digits) |
| Month | MMM (name or abbr.) | MM (2 digits), M (1 or 2 digits) |
| Month | NNN (abbr.) | |
| Day of Month | dd (2 digits) | d (1 or 2 digits) |
| Day of Week | EE (name) | E (abbr.) |
| Hour (1-12) | hh (2 digits) | h (1 or 2 digits) |
| Hour (0-23) | HH (2 digits) | H (1 or 2 digits) |
| Hour (0-11) | KK (2 digits) | K (1 or 2 digits) |
| Hour (1-24) | kk (2 digits) | k (1 or 2 digits) |
| Minute | mm (2 digits) | m (1 or 2 digits) |
| Second | ss (2 digits) | s (1 or 2 digits) |
| Millisecond | ll (3 digits) | l (1, 2 or 3 digits) |
| AM/PM | tt (2 digits) | t (1 or 2 digits) |
For timestamp outputs some nodes has the ability to define the format of the timestamp. Therefore different pre defined formats exists or a free format definition.
The formats are:

| yyyy | Year represented by four digits. |

| '…' or "…" | Literal character sequence. Surrounding quotes are removed. |
| UTC: | Must be the first four characters of the mask. Converts the date from local time to UTC/GMT/Zulu time before applying the mask. The "UTC:" prefix is removed. |
For timespan output the calc-timespan node has the ability to define the format of the timespan. Therefore different pre defined formats exists or a free format definition.
The formats are:
A condition usually consists of a property, an operator and depending on the operator, a threshold.
property, an operator:
property, operator and threshold:
The operators are:
is true - the value of the property must be of type boolean and the condition is fulfilled if the value is trueis false - the value of the property must be of type boolean and the condition is fulfilled if the value is falseis null - the value of the property must be undefined or nullis not null - the value of the property can have an obscure value that is not undefined or nullis empty - the condition is fulfilled if the property is an empty string, array, buffer or an object with no propertiesis not empty - the condition is fulfilled if the property is an string, array, buffer which is not empty or an object which has propertiestrue expression - the condition is fulfilled if the property is a number and greater 0 or a Boolean which is true or a string containing one of the following values true, yes, on, ja. If the property has a string switchon then this would evaluate to true, because on is part of the string.false expression - the condition is fulfilled if the property is a number and less than or equal 0 or a Boolean which is false or a string containing one of the following values false, no, off, nein. If the property has a string nonsens then this would evaluate to true, because no is part of the string.not true expression - the condition is fulfilled if the property is a number and not greater 0 or a Boolean which is not true or a string containing none of the following values true, yes, on, ja. It the property is a number and NaN then this would evaluate to true.false expression - the condition is fulfilled if the property is a number and not less than or equal 0 or a Boolean which is not false or a string containing none of the following values false, no, off, nein.<, <=, ==, !=, >, >= - compares the value of the property with a threshold. Typically this makes only sense if the property and the threshold are numbers.contain - the condition is fulfilled if the property contains the string defined in the threshold.containSome - the threshold must be a string separated with comma ,, semicolon ; or pipe |. The condition is fulfilled as soon as only one of the separated parts of the threshold string is is included in the property value.containEvery - the threshold must be a string separated with comma ,, semicolon ; or pipe |. The condition is fulfilled as soon as all of the separated parts of the threshold string are included in the property value.A JSONata expression in the property must be always a boolean with value true, in this case the operator can not be chosen.
