Hold state of GIPIO LOW during deep sleep mode

[ribbles]

Operating environment/Installation (Hass.io/Docker/pip/etc.):

Hass.io

ESP (ESP32/ESP8266, Board/Sonoff):

ESP32 TTGO T-Display

ESPHome version (latest production, beta, dev branch)

1.15.3

Affected component:

deep_sleep, switch & sensor pmsx003

Description of problem: I would like to put the pmsx003 sensor to sleep when I put the ESP32 to sleep, to save batteries. I can put the pmsx003 to sleep, but when the ESP32 goes to sleep, the pmsx003 sensor turns back on, presumably because the PIN has been reverted to open. I used an RTC pin under the impression that they remain set during deep sleep.

      then:
        - switch.turn_off: pmsx003_sleep
        # so we can hear that it goes to sleep

Additional information and things you've tried:

[rradar]

I'm not entirely sure but I think this can only achieved by hardware design.

[ribbles]

Noob issue. 10k resistor to earth. Resolved.

[adiman29]

i have the same problem and 10k resistor not working. I using wemos d1 mini

i have the same problem and 10k resistor not working.

I using wemos d1 mini

I started at 10k, but ended up needing a 5k1 to got the voltage low enough. Try using a volt meter?
