Can't get esphome ultrasonic++ working

ESPHome

Hi
I’m setting up a nodemcu with ultrasonic sensor and some switches for lights control (via solid state relays).
Configuring seems to be ok. OTA update works fine.
I’m using the built-in mosquitto integration, hassio 90.1. Discovery is enabled
When I’m starting up, I get this:
INFO Reading configuration…
INFO Starting log output from 192.168.10.45 using esphomelib API
INFO Connecting to 192.168.10.45:6053 (192.168.10.45)

over and over again.
The switches don’t show up anywhere either.
The controller1 switches between online and offline quite often in the esphome dashboard.
The IP is correct (static), and I can ping it.

Help, please? Where can I start looking?

Hi, suggest you look into this : https://esphome.io/index.html Fantastic work by @OttoWinter !

I got my ESP8266 to work with 3 ultrasonics using this method. Start with “Getting started with Hass.io add-on”

My config, if it helps is pasted below

esphome:
  name: mcu2
  platform: ESP8266
  board: nodemcuv2

wifi:
  ssid: "mywifi"
  password: "mypassword"

# Enable logging
logger:

# Enable Home Assistant API
api:
 password: "xxx"

ota:
  password: "xxx"

sensor:
  - platform: ultrasonic
    trigger_pin: D1
    echo_pin: D2
    name: "Salt Sensor"
    update_interval: 5s
    filters:
      - filter_out: nan
      - lambda: return (1-x)/1*100;
  - platform: ultrasonic
    trigger_pin: D7
    echo_pin: D8
    name: "Tank 1"
    update_interval: 5s
    filters:
      - filter_out: nan
      - lambda: return (3-x)/3*100;
  - platform: ultrasonic
    trigger_pin: D5
    echo_pin: D6
    name: "Tank 2"
    update_interval: 5s
    filters:
      - filter_out: nan
      - lambda: return (3-x)/3*100;

Solved it! I had copied an old config file that used mqtt, but this one shouldn’t. Removed mqtt section, and it works :slight_smile:
