I created a flow which triggers the sun screens to go in when it’s raining.  
It uses Openweathermap and it triggers when the chance on rain has changed and is above 50%.  
But now it also triggers when it changes for example from 80% to 70%. Is it possible to create a flow (normal or advanced) which only triggers when the change on rain becomes more than 50% and not if it is already above 50%?

This is my current flow: [Shared Flow | Homey](https://homey.app/f/ZglIke)

Haven’t tried that one, will certainly do, because OpenWeathermap is absolutely not accurate in my hometown with regards to the amount of rain and weather status.

You can make a yes/no with a logic card  
You first have to make a logic card yes/no.

IF chance changes  
AND greater then 50%  
AND logic card is yes  
THEN zet status omlaag  
THEN set logic card to no

IF chance changes  
AND smaller then 50%  
AND logic card is no  
THEN set logic card to yes

Maybe this will work.

Why don’t you use this trigger card?
