I will receive my screens i a couple of weeks, so i am glad you made the flows . I would only change some small stuff in your up flow AND… part.
Now you have (status = up and bewolking > 90) OR windsnelheid >50 OR regen > 1. If it rains or there is wind it will send commands to your screens every 5 min, even when its already up.
I would add the status to all 3 OR part. if its up its up.
About the triggering every 5 min. If you change it to trigger on lux, the wind and rain stuff doesn’t work anymore, you will need extra flows for that then.
don’t know if this will work, but to minimize the 5min load a bit you can disable the down flow when its down and disable the up flow when the screens are up.
