Automation conditions and triggers

Configuration
1

Hello, I recently successfully added a Sonoff relay to my ventialtion system and I can now trigger extractor fan when either 2 bathrooms or kitchen humidity goes over a certain level (70% for bathrooms and 60% for kitchen) and turn off if all three are below the set humidity level OR if time is after 10PM or before 6AM (basically ventilation should never be triggered between 10PM and 6AM)

Originally I’ve made 3 automations, for each bathroom and the kitchen plus another 3 automations to turn ventialtion off based on the humidity of the 3 rooms and a another automation to turn off after 10PM, for a total of 7 automations…

I then realised I can definetely simplify that, am I correct in understanding that each trigger in the automation is considered on its own?

Here my 2 automation for ventilation ON and ventilation OFF:

Yes.

You need to make a small change to the “off” automation. For the conditions to be affected by the “OR” they all need to be nested under the Or condition.

ah brilliant thanks, that is somehow counterintuitive and I just come home to the ventilation still running despite humidity being below the level everywhere.

And this will still ALWAYS shut it off at 22:00:01 right? Because how it visualised make me thing it needs to be AFTER the time AND below level… even thought it’s saying "Test if any of 2 conditions matches… so that should be ok, is just weird to see the OR and then the “and” but I understand is not a logical AND is just “and also evaluate this other conditions…”

It might help to think about it like distribution in algebra instead of reading it like a sentence.

Because of the order/application of conditions in you original, the Or was only being applied to the time condition. The entire condition block could only ever pass after 22:00:01.

As long as Home Assistant is running, yes. It also produces an edge case where if the fan is running after 22:00:01 and any of the sensors trigger the automation by falling below threshold it will be turned off (even if only 1 of 3 sensors is below threshold)… If that’s not okay, you’ll need another condition inside the And block.
