multiple motion probe inputs

Reopening an old tread, happy to add a new one if this has no traction.

I read the above and get some of the concepts but no idea what I would need to do. Two probes. A and B which cannot be linked manually without hardware.

What I need is probe = input A OR NOT(input B  ).

I dont mind if that OR is a MUX or other construct. I dont mind if the probe has to stay plugged in or not, at this point just trying to get the most basic first step.

currently I have:
motion.probe-input = probe-in = hm2 7i96s.0.gpio.000.in

How do I add in:
hm2 7i965.0.gpio.001.in_not

Forgive me but the very very basics are tripping me up, I need a toe hold. I think I'll be fine after that.

If needed I'll make it out of hardware - for me this right now seems the easier solution which makes me think I'm missing something.

Kind regards.

You can simply use the "or" component to
combine hm2 7i96s.0.gpio.000.in and
hm2 7i965.0.gpio.001.in_not pins but this
assumes that the unused input cannot be true.

The mux system is a bit safer but requires
a signal to select which input you want to use.

Sorry for not getting these things earlier.

So in the custom hal I added two objects.
or2 and and2.

then I did

or2.0.in0 = probe A
and2.0.in0 = motion.digital-out-00
and2.0.in1 = probe B
or2.0.in1 = and2.0.out
motion.probe-input = or2.o.out

In other words, if P64 P0 is on then the and gate enables probe B. P65 P0 will then disable it again.

It seems to work but around long enough to know that I've missed something.

ps. I see a custom.hal, does a custom.ini exist?
