sunrise/sunset by SmartThings requires internet access to lookup your sunrise and sunset times from a website/cloud based on you zipcode. I would like to a app that calculates the times uses latitude and longitude. I don’t like being dependent on connectivity and the cloud!!! Keep offsets and it would be nice to be able to select from Actual Time, Civil Twilight, Nautical Twilight, and Astronomical Twilight.
here is great razberry app that calculated the times…
