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.

Information on Version changes

If a Node has a warning sign on the label like this one: warning sign This is not an error, it hides only that the node needs to be opened, saved and deployed to fix the label.

Nodes that were created or saved with a version 2.0.0 or later do not work in versions prior 2.0.0 of the package.

Table of contents


These nodes need at least NodeJS Version 8.0 and Node-Red with Version 1.0! Any early Version of Node-Red will not work!


npm install node-red-contrib-sun-position


Saving resources

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.

second based accuracy

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.
