Hi !
I did the job !
It works. A Node-red flow :
If you want to import it :

It does 2 things:
- create the entity ephemeris(*) which contains all the sun events of the current day with their hour
- fire an event when it’s time, this for each event managed by the node-red plugin node-red-contrib-sun-position.
This flow use the node-red-contrib-cron-plus too.
Data are calculated at 3h30 AM to avoid daylight saving time change problems (at 3h AM).
Please, if you use it and improve it, tell me ![:kissing_closed_eyes: :kissing_closed_eyes:](https://community.home-assistant.io/images/emoji/twitter/kissing_closed_eyes.png?v=9)
