quiet siren
Hi all,
I’m currently using a Shelly Plus Uni to monitor door states via its IN1 and IN2 inputs. That works perfectly for two doors.
However, I’d like to monitor a third door (pedestrian entry gate) as well, without adding another module.
Is there any way to use an additional input, like the analog input (ADC) on the Shelly Plus Uni, to act as a third digital input for a reed switch or similar sensor?

i imagine an analogue input will probably be able to detect a high/low.
instead of seeing it as on/off it might see it as something like 3.3v/0v which you could then use I guess
never used the uni myself but electronically i dont see any reason why you couldnt make it work

guess i'll try, maybe with adding a pull-up resistor too
