I already have a light switch with 24V status LED.

What I mean is:

For my local regulation, it is not allowed that the relay provides 240V AC to light and that the light LED status is off.
Let's say i program a script in home assistant that turns status LED on/off, and home assistant is not working, then the status LED is possible not accurate (off when light is on, or on when light is off). This is not allowed.

With the code I gave (that I still need to test), I made sure that the LED status logic remains local on F24 board. So even if HA is down, the led status still works.
I think this is the most robust way to program it?

The best would be a hardware solution, maybe something for a future board? Where there is a board with double relay for one switch. One for 240V AC and one for 24/12V DC for status LED. On local switch push, or button press via HA both relays enable via hardware. Not via software.
