Floating inputs are changing state
#1
I have a v1.6 board that is currently not connected to anything; it is powered with a quality mean well 12v power supply. 

The integration into home assistant is made using your example yaml for Esp home (included).

The problem is some of the inputs will randomly toggle on and off.. From my reading, the PCF8574P has an internal weak pull-up, so it should not read a signal unless there's sufficient input on the optocoupler, which would require pulling the input down to ground.


Any ideas what could be causing this?
