I’m trying to use the mode: INPUT_PULLDOWN option with my defined binary sensors and having no success.
The docs say it’s supported for ESP32 but I can’t get mode: INPUT_PULLUP to compile either.
My config looks like this:
binary_sensor:
- platform: gpio
pin: GPIO18
name: "Drum motor toggle"
id: drum_motor_toggle
mode: INPUT_PULLDOWN
on_press:
then:
- switch.toggle: drum_motor
Firstly, is my assumption correct that INPUT_PULLDOWN should be supported and will using it obviate the need for a pull-down resistor when connecting a switch?
I’d appreciate some help. I’ve been at this for ages!
Maybe this ?
binary_sensor:
- platform: gpio
pin:
number: D18
mode: INPUT_PULLDOWN
name: "Drum motor toggle"
id: drum_motor_toggle
on_press:
then:
- switch.toggle: drum_motor
Yes, that’s correct, if you connect the switch to +3.3v and the gpio pin. If you connect the switch to gnd and the gpio, use INPUT_PULLUP

Thank you so much for the help.
What’s the difference between using D18 and GPIO18?
I don’t have a preference, I’d just like to understand.
Don’t know really, thats just how its shown in the docs
I just tried this. Still no compile. It fails at the number: D18 line.
INPUT_PULLUP gets the same result.
Can you post your whole YAML ?
I just changed it back to GPIO18 and it compiles with both INPUT_PULLUP and INPUT_PULLDOWN.
Seemingly sorted. Thank you.
binary_sensor:
- platform: gpio
pin:
number: GPIO18
mode: INPUT_PULLDOWN
name: "Drum motor toggle"
id: drum_motor_toggle

- switch.toggle: drum_motor
Strange, I use the Dx pin numbers exclusively. I’ll bear it in mind for the future
