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.
This is still in development! This is not fully tested and documentation are missing!

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 context property which must be of type boolean. If this property is true alternate time will be used.
Alternate time optional defines an alternate start time which will be used if the property is true. 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
time-inject-settings-addProp1
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.

A simple node that routes messages depending on the time. If the current time falls within the range specified in the node configuration, the message is routed to output 1. Otherwise the message is routed to output 2.
⎇ sign after a time will show that an alternate time is used.
⎇ sign after a time will show that an alternate time is used.
if the message was pass through the timestamp of this message will be shown.
time limits options, otherwise the last message status display.A enhanced node for time format change and time comparison.

A simple node that routes messages depending on the time. If the current time falls within the range specified in the node configuration, the message is routed to output 1. Otherwise the message is routed to output 2.
Without defining any comparison, the node allows by only defining inputs and result a simply timespan calculation.
The time definitions of the nodes has different configuration possibilities
manual timestamps can be entered 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 secondsfollowing Sun times can be chosen:
| Time | Description | SunBH |
|---|---|---|
astronomicalDawn | night ends (morning astronomical twilight starts) | 18 |
amateurDawn | amateur astronomical dawn (sun at 12° before sunrise) | 15 |
nauticalDawn | nautical dawn (morning nautical twilight starts) | 12 |
blueHourDawnStart | blue Hour start (time for special photography photos starts) | 8 |
civilDawn | dawn (morning nautical twilight ends, morning civil twilight starts) | 6 |
blueHourDawnEnd | blue Hour end (time for special photography photos end) | 4 |
sunrise | sunrise (top edge of the sun appears on the horizon) | 0.833 |
sunriseEnd | sunrise ends (bottom edge of the sun touches the horizon) | 0.3 |
goldenHourEnd | morning golden hour (soft light, best time for photography) ends | -6 |
solarNoon | solar noon (sun is in the highest position) | |
goldenHourStart | evening golden hour starts | -6 |
sunsetStart | sunset starts (bottom edge of the sun touches the horizon) | 0.3 |
sunset | sunset (sun disappears below the horizon, evening civil twilight starts) | 0.833 |
blueHourDuskStart | blue Hour start (time for special photography photos starts) | 4 |
civilDusk | dusk (evening nautical twilight starts) | 6 |
blueHourDuskEnd | blue Hour end (time for special photography photos end) | 8 |
nauticalDusk | nautical dusk end (evening astronomical twilight starts) | 12 |
amateurDusk | amateur astronomical dusk (sun at 12° after sunrise) | 15 |
astronomicalDusk | night starts (dark enough for astronomical observations) | 18 |
nadir | nadir (darkest moment of the night, sun is in the lowest position) |
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
The following time parameters are exists in the output for backward compatibility. These are equal to parameters in the table above:
| time parameter | is equal to |
|---|---|
dawn | civilDawn |
dusk | civilDusk |
nightEnd | astronomicalDawn |
night | astronomicalDusk |
nightStart | astronomicalDusk |
goldenHour | goldenHourStart |
moon rise and moon set can be used
any message, flow or global property which contain any of the following types:
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:
| placeholder | Description |
|---|---|
| d | Day of the month as digits; no leading zero for single-digit days. |
| dd | Day of the month as digits; leading zero for single-digit days. |
| ddd | Day of the week as a three-letter abbreviation. (same as E) |
| dddd | Day of the week as its full name. (same as EE) |
| E | Day of the week as a three-letter abbreviation. |
| EE | Day of the week as its full name. |
| M | Month as digits; no leading zero for single-digit months. |
| MM | Month as digits; leading zero for single-digit months. |
| MMM | Month as a three-letter abbreviation. |
| MMMM | Month as its full name. |

| xx | difference of days from timestamp day to output day with relative names for today, tomorrow, ... |
| '…' 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.
