moon-position - Node settings

moon-position-settings

Position connects to the central configuration node, which contains the current position, but also handles internal shared functions
Topic defines the topic of the first output
position container here you can define multiple lower and upper limits for azimuth. If the calculated value of the azimuth is inside the defined limit the input message will send to the associated output.
Name name of the Node

moon-position - Node Input

The Input is for triggering the calculation.

It is possible that the incoming message have properties msg.latitude and msg.longitude (or msg.lat and msg.lon) defined to override settings in configuration node. The configuration node still needs to be configured properly.

moon-position - Node Output

first output
- msg.payload.azimuth the azimuth of the moon position relative to the given coordinates.
- msg.payload.altitude the altitude/elevation of the moon position relative to the given coordinates.
- msg.payload.distance the distance of the moon.
- msg.payload.parallacticAngle the parallacticAngle of the moon.
- msg.payload.illumination the illumination of the moon as object.
  - msg.payload.illumination.angle the illumination angle of the moon.
  - msg.payload.illumination.fraction the illumination fraction angle of the moon.
  - msg.payload.illumination.zenithAngle the illumination zenith angle of the moon.
  - msg.payload.illumination.phase the illumination phase of the moon as object.
    - msg.payload.illumination.phase.value the current phase of the moon in percent, where 0%/100% is New Moon, from 0% to 50% is growing, 50% is Full Moon and >50% is decreasing.
    - msg.payload.illumination.phase.angle the current phase angle of the moon.
    - msg.payload.illumination.phase.emoji the emoji of the current phase of the moon.
    - msg.payload.illumination.phase.code the code of the emoji for the current phase of the moon.
    - msg.payload.illumination.phase.name the name of the current phase of the moon.
- msg.payload.times the moon times as object.
  - msg.payload.times.rise the moon rise time.
  - msg.payload.times.set the moon set time.
  - msg.payload.times.alwaysUp boolean which is true if the moon never rises/sets and is always above the horizon during the day.
  - msg.payload.times.alwaysDown boolean which is true if the moon is always below the horizon.
- msg.payload.pos array with a boolean of every defined limit of the azimuth, which is true if the azimuth is inside the limit.
- msg.payload.posChanged boolean which is true if any of the defined limit of the azimuth has changed to the last calculation.

second output to ... output if limits for azimuth are defined the incoming message will send to this output. It adds a msg.payload.posChanged property of type boolean which is true if the limit has changed since the last azimuth calculation.
