The lights were controlled by a RFXCom RFXTRX433 USB device.

The whole system ran on a Raspberry Pi we have hanging on the wall. I used the original version of this node in my own set up to turn on house lights at dusk.

There are two example flows provided, one for a fixed GPS positioned injected daily and one for a stream of GPS coordinates that continually updates with your position.Įxample 2: Stream of GPS positions Download Say Thanks Please note, I show the use of 2 inject nodes, one to invoke the flow on deployment and the other to invoke the flow at a fixed time each day. The Inject node supplied with node-red is a good candidate for this and is demonstrated in the supplied example flow. In keeping with the general guidance for node-red nodes you must now use some other node to invoke the sun-events node at a time and frequency appropriate for your use case. Unlike previous versions of this node, this node DOES NOT perform it's own daily scheduling. Obviously the Sun events won't fire at their correct times but if you are testing your flow it means you won't have to wait for hours to see that things are working. Reduces the time you have to wait for an event to fire, 1 hour becomes 1 minute.

Make Hours seem like minutes (test mode):.

Topic: Set the topic used in the flow from this point onwards Name: Override the default name of this node in the flow The msg.topic can also be set in the node's configuration.

It also outputs the event name and date & time of the event in msg.sunevent object if you need a more complete set of Sun event data. The Sun event name is output in, preserving any other payload values set earlier in the flow.

If you have a frequently changing GPS position it will update the Sun event calculations every time it receives a new latitude and longitude in the payload. This node requires a latitude and longitude in decimal form to be passed to it in the msg.payload, either : = Ĭalculations are performed using the Latitude and Longitude that are passed in via the payload. The easiest way to do this is with the node-red Inject node. To have the node output events reliably every day, you should inject a latitude and longitude payload into the node at least once every 24 hours. UsageĮach time this node receives a new msg.payload to it's input, it calculates up to 2 days worth of Sun events (depending on what time of day it is invoked). Intervals to recalculate the next 24 hour's events, but this payload can be any value. You must still inject a payload at regular Sun events if no latitude and longitude coordinatesĪre passed in the msg.payload. The latitude and longitude you defined in the node's configuration can be used to calculate Require a change to your flow if you are upgrading from a previous version. The latest version (v3.0) of this node works a little differently to previous versions and will

nadir: nadir (darkest moment of the night, sun is in the lowest position).

dawn: dawn (morning nautical twilight ends, morning civil twilight starts).

nauticalDawn: nautical dawn (morning nautical twilight starts).

nightEnd: night ends (morning astronomical twilight starts).

night: night starts (dark enough for astronomical observations).

nauticalDusk: nautical dusk (evening astronomical twilight starts).

dusk: dusk (evening nautical twilight starts).

sunset: sunset (sun disappears below the horizon, evening civil twilight starts).

sunsetStart: sunset starts (bottom edge of the sun touches the horizon).

solarNoon: solar noon (sun is in the highest position).

goldenHourEnd: morning golden hour (soft light, best time for photography) ends.

sunriseEnd: sunrise ends (bottom edge of the sun touches the horizon).

sunrise: sunrise (top edge of the sun appears on the horizon).

On receiving a msg.payload containing latitude and longitude coordinates (in decimal), this node outputs a series of Sun event objects at the appropriate time for each.Ĭalculations are performed using the excellent SunCalc moduleĪnd the resulting Sun events are output from this node at the appropriate time: This node can be used to make something happen based on a particular period of the day, for example switching on your lights at home at dusk every day or taking a photo a the darkest time of night ("nadir"). A node for node-red that generates events based on the position of the Sun at the appropriate time of dayĪ node that generates events based on the location of the Sun at the appropriate time of day.
