Thoughts and troubleshooting:

1. Your kitchen light switch - Is this a standard wall switch? i.e. it physically turns the power off to the kitchen light, or is it a "Pushbutton", or light in the UI, that controls the kitchen light through Home Assistant? If it is a physical switch then this isn't going to work because as far as home assistant is concerned all that has happened is that the kitchen light was "Unavailable" for a short period, not that it was "Turned off".
2. For troubleshooting - go through each scenario and see whether the PIR automation gets turned off or not [Configuration -> Automations]. (My guess is that it doesn't. If it were off then it wouldn't turn off the light after the timer finishes).

The lights are connected to a Shelly 1PM and the physical wall switch is connected to the SW input of the Shelly.
The PIR is an ex-alarm PIR connected via a Konnected board.
I could have sworn it was working but I'm doubting myself now. I'm going to shorten the timeouts and do some controlled testing now I have the house to myself.

This is beautiful work. Thanks. One thing for me is due to the size and layout of the kitchen, I use two motion sensors as potential triggers. Is there a way to do that here?

I don't have a setup or time to modify myself, but I think it should be pretty simple. Have a go yourself!

I think you would only need to modify the "Trigger" elements of the first script, no changes to the second script should be needed:

1. Duplicate the "motion_entity" part of the "Input" section, but give it a different name
2. Change the "trigger" section to add the second "motion_entity", but use the new name you have given it - This needs to be done as a "list" in YAML (It needs the dashes before the item) See an example in the second script from lines 36-46

Remember to reload blueprints and re-create the automation from the modified blueprint every time you modify it and before you test.

I’ll give it a go. Thanks. \\\\ Greg

Found this on using multiple trigger entities

And here's where I wound up:
(Thanks for the challenge)
