Broadcast message when window opened and then humidity stops falling

[candid valley]

I am attempting to create a voice reminder letting me know I can close the windows after I have opened it and humidity has stopped falling.
I am using a trend helper to get the trend data.

I am struggling with the part where the automation is waiting for the condition to be met. I have read I should not use the wait for option, as it is not persistent across restarts.

What is the next simplist solution (wait for sounds exactly like what I need :X )

1. don't use device triggers if you can help it - state triggers are better and wayyy more readable
2. conditions are there to stop it running when a trigger goes off - so WHEN TRIGGER - IF CONDITION - DO ACTION

So for this - what you could do is move the condition to a "wait for" block in the action before the tts.speak, and i'd also put a condition around the tts speak that checks the window is still open
