I’ve created a small python script that generates and SVG image to illustrate where the sun is currently positioned and which side of the house is facing the sun. I wire the script up with a rule when the sun’s azimuth changes and then I include the SVG in my HABPanel like this: [image] It’s not…

Hi Vincent, Just updated the script with the “print (ts)”, and here’s the log output: python /etc/openhab2/scripts/shaddow.py update 1522389308.06 120.558989318 21.6981129979 Done in 0.64107298851 seconds

Ok, now compare the 1522389308 with the actual time This number is a unix timestamp, you can paste it in Unix Time Stamp - Epoch Converter Epoch and unix timestamp converter for developers. Date and time function syntax reference for various programming languages. …

I see :slight_smile: I learn new stuff everytime i visit this forum. It’s great!! :slight_smile: So, I pasted a fresh value in the link provided. My value= 1522407311.87 Converted = 03/30/2018 @ 10:55am (UTC) Local time when executed= 12:55am So It seems I’m 2 hours behind in the astral setup. T…

Cool, 2 hours… Now change the script as follow a little bit further down in the code: ... self.sunrise_azimuth = float(self.astr.solar_azimuth(self.sun['sunrise'], LATITUDE, LONGITUDE)) self.sunset_azimuth = float(self.astr.solar_azimuth(self.sun['sunset'], LATITUDE, LONGITUDE)…

okay. Thanks for your time and help. Looking forward to hear from you, and possibly a clever solution :slight_smile:

Hi Vincent. Not to push or anything, but I’m just curious if you’ve though some more on my little astral issue? :slight_smile:

Sorry, easter week-end and all. I was wondering, perhaps wrongly, but just to make sure… From your post #84, there is 30d difference betwwen what astral gives you and what OH astro binding gives. 30 degrees is 2 hours of sun movement, give or take. So either astral is wrong or OH is wrong… So I…

Yeah, easter holiday makes it much harder to get time, for my home automation hobbies :smiley: But I have finally got around and tested your solution. Unfortunately there is no change though. I also tried to force reinstall the astral libraries. I can also confirm that OH2 has the right astro data, …
