Hi,

I'd like to automate our shutters. In particular, I'd like to have opening- and closing times varying over the year. I could of course try to use solar events, but so far I did not really find a satisfying setting as I would often prefer earlier / later times than the typical solar events.

What I would like to to instead is to use a step-wise function with arbitrary support points.

Example:

I would like to have the possibility to provide a number of dates (or invervals) and times when the node should be executed.

Does anybody have an idea how to achieve that? Any pointer is highly appreciated.

Thanks  
Sebastian

node-red-contrib-cron-plus is more than capable of triggering multiple datetimes.

You can even set schedules dynamically (at runtime) via a `msg`
