I’m putting together a flow chart so that I can visualise how I want my circadian lighting to function. A lot of Visual Effects software, as well as Programmable Logic Controllers (PLCs) use flow charts to actually build the automations.
I realise this isn’t something that’s going to happen in HA overnight, but I would love to see it as a long-term goal!
In the meantime, I’m just happy that I’ve found Home Assistant, as it’s a huge improvement over OpenHab, from which I am currently switching.
I’ve included a picture of the Houdini (Visual Effects) interface for reference.
there is an app that should be exactly what you want (but it’s not built-in to HA itself) that’s called Node-Red.
you can install it as an add-on if you have supervised install method (HAOS or HA Supervised) or in a standalone docker container if you use HA Container.
Once installed you can create automations there that tie back into HA and use HA entities/devices as inputs or outputs.
