Hello!
So I’ve been working all day on the subject, and I have 3 proposals to address the different issues 
I’m responding here because it’s a topic where we talk about scenes, but it has nothing to do with the title of the topic. Once we agree, we can rename the development.
The Problem
I started from the different needs, without thinking about the product, just the final need:
- Be able to turn off the light in a room if there is no movement for XX minutes
- Be able to receive an alert if the fridge temperature drops below 10°C for at least 1 hour.
- Be able in a scene to execute actions only if the sun is in the state of rising/setting/before sunrise minus 10 minutes, after sunset plus 30 minutes, etc..
- Be able to execute a scene (or part of a scene) according to a time condition. Example: if it is before 12 p.m./after 2 p.m./between 12 p.m. and 2 p.m./on Tuesday, Wednesday and Thursday between 7 a.m. and 8 a.m./and many others.
Based on this specification, I dug a bit into how we could have this in Gladys.
I quite liked what home assistant did on the « maintain a condition for XX minutes » part, and I went for a solution close to theirs for this part.
After that, I still have some questions (marked on the document), not everything is clear on the functional side.
The mockups (with explanations) are available here: New scenes triggers/conditions/actions

What do you think?
@lmilcent In the end, it’s very different from your proposal 
Sorry, to save time I went with what I saw, and then we can indeed see what best addresses the issues.
Note: If you have cases that are not well covered by my proposal, feel free to bounce back on them I’m talking about practical and concrete cases at your place, we’re really in practice here, not in theory.
