I have a USB camera pointed at my backyard. It takes a picture every 5 minutes, one minute before weewx does it's calculations and uploads (i.e. picture at 04, weewx at 05 and so on.) It works fine now on a cron job every 5 minutes, 24/7.
I want to enhance it to just take pictures during daylight hours. My thoughts are to put a time check in my .bat file that runs every 5 minutes. Something like: IF (DAYLIGHT) TAKE_PICTURE ELSE FORGET_IT sort of thinking. Is there a better way (from a Linux bash script, not Python) than parsing /home/weewx/public_html/index_html to obtain these values? I'm looking for the simplest solution. I'm hoping I can make DAYLIGHT a boolean that is something like this: DAYLIGHT = ((time > Start civil twilight) AND time < (End civil twilight)) I could use Sunrise and Sunset instead if they are easier to obtain. I'd like to upload this photo to my weewx web site, and I can now except well over half of them are taken in the dark. I want to put a .jpg there that says something like "Next photo update at sunrise" or similar. Thoughts? Better ideas? - Paul -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
