Conditional Switch Turn on - OH3

Setup, Configuration and Use Scripts & Rules

@ubeaut what about your setup? i still find that calling the dusk dawn channels from astro works best as triggers for my virtual switch which defines night and day but I understand that there maybe a channel that does this anyway and i could use that as a trigger?

I donā€™t use a virtual switch to see if it is night or day.
I use the Astro sun phase name. You can see if it is night or daylight from that.

Basically I use if the phase name is not equal to daylight then it is getting dark or itā€™s dark which covers what I want to do.

Iā€™ve read several threads where youā€™ve mentioned using the sun phase name channel.
Question: what version of openHAB are you using?

Iā€™ve set up a test system (Pi4) with latest stable openHABian, astro binding is the only binding installed and sun phase name is constantly returning UNDEF
A restart of openHAB causes it to report the correct sun phase name for a brief time but it quickly returns to UNDEF
Iā€™ve checked the state using REST, rules logging out state and value in UI all return UNDEF

Hi.

I am currently not at home to give you a complete answer but I am using openhab 3 latest stable version. I am running on Ubuntu 20.04.
It is not openhabian.
The only thing it sounds like to me is the latitude and longitude may not be correct and the astro binding cannot calculate anything.

Also check the date and time as you donā€™t have a real time clock in the pi.
