Use Shelly i3 to only detect hot wire on DC & not common nor ground

I am trying to use a Shelly i3 to monitor the floats on my Zoeller lift station with the following configs…

substitutions:
  device_label: Lift Station
  device_name: lift_station

  sensor_1_class: moisture
  sensor_1_id: lift_station_lag
  sensor_1_name: Lift Station Lag

  sensor_2_class: moisture
  sensor_2_id: lift_station_stop
  sensor_2_name: Lift Station Stop

  sensor_3_class: moisture
  sensor_3_id: lift_station_lead
  sensor_3_name: Lift Station Lead

  update_interval: 5min

<<: !include _libs/shelly_i3.yaml

  - platform: gpio

    pin:
      number: GPIO14
      mode: INPUT

    filters:

  - platform: wifi_signal
    name: ${device_label} WiFi Signal
    update_interval: ${update_interval}
    filters:
      - median:
          window_size: 10
          send_every: 5
          send_first_at: 5

# status_led:
#   pin:
#     number: GPIO0
#     inverted: yes

switch:
  - platform: restart
    name: ${device_label} Restart

I cannot for the life of me figure out how to make it only trigger on the hot 120 wire. It will trigger on the hot, common & ground.

Can anyone point me towards what I am doing wrong with me config?

I have tried to sed mode to INPUT_PULLUP, but that did not get it either. Would appreciate any advice that any of you may have.
