Water level sensor "measurement timed out"

ESPHome
7

I just tried it, and had the some behaviour. But no success :pensive: Just to make sure, here is my yaml:

esphome:
  name: acidtanklevel
  platform: esp8266
  board: d1_mini

# Enable logging
logger:

# Enable Home Assistant API
api:

ota:
  password: "334210fbabf6aa3e4702ee0cdcd21495"

wifi:
  networks:
  - ssid: "Pumproom"
    password: "prpw"
  - ssid: "Office"
    password: "offpw"
    
  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Esphome-Web-tanklevel"
    password: "tanklevel"
    
sensor:
  - platform: wifi_signal
    name: "WiFi Signal Sensor"
    update_interval: 60s          #to display WiFi signal strength
# Acid Level Sensor    
  - platform: ultrasonic
    trigger_pin: D5
    echo_pin: D6
    unit_of_measurement: "%"
    icon: "mdi:water-percent"
    accuracy_decimals: 1
    timeout: 20m
    update_interval: 30s
    name: "Acid Tank Level"              #You may change the tank name
       
    filters:
      - lambda: return (1-((x-.10)/1.10))*100;
      - filter_out: nan

If that is all correct, the only thing for me to try is taking a whole new set and sold it together again.
