GPIO sensor wiring - Lighting remote control
GPIO sensor wiring - Lighting remote control
Lighting on/off remote control is one example of what an output relay may switch
and control.
An external Pullup voltage connection is recommended when connecting GPIO
sensors to the Cortex Hub. When a sensor does not provide more than 2V, the
Pullup provides an appropriate high level reference for the Cortex Hub’s input.
