Hi,
I’m new to Hass.io and ESPHome and am currently trying to transfer my Domoticz/ESPEasy weather station into Hass.io. …but really struggling with the MQTT configuration.
My setup is a Raspberyy Pi 3 b+ with Hass.io v2.12 installed. I’m using ESPHome on 2 x NodeMCU boards to support a BME280 (with Temp, pressure and Humidity) and to send the sensor data to the other unit where a 4 x 20 LED should display the results.
So far, I’ve successfully connected a DHT11 to the unit with the LED and can display the Temp and Humidity sensor values. The other unit (with the BME280) can send THP sensor values to my MQTT.fx to view the sensor data. However, the problems I’m having are that I really don’t understand how to configure the following:
-
…to configure the BME280 NodeMCU unit to publish the sensor data on an MQTT topic of my choice.
-
…to configure the NodeMCU unit (with the LED) to subscribe to the other units sensor data so that I can display the remote BME280 sensor data in the LED.
I’ve spent days playing around with the settings but just not making any significant progress.
I’ve provided the following yaml file to show progress so far but would appreciate any help i getting this sorted. If any further details required then more than happy to provide them.
Thanks in anticipation.
The ESPHome unit with the BME280 unit has yaml file…

Update as needed to make some progress.
I uninstalled the MQTT package I was using and cleaned out the configuration.yaml of any mqtt references. I then installed the package “MQTT Server & Web client” v1.1.0 (i.e. the one with Hivemq’s web client) and managed to get the web-client working with test topics. The problem is that I still can’t find the right mqtt confurations settings to use in one of my ESPHome commands as when I upload it to the device i get the mqtt error…
========================= [SUCCESS] Took 27.62 seconds =========================

The configuration.yaml mqtt config is…
mqtt:
broker: 192.168.1.120:1884
username: robshamqtt
password: xxxxxxxxxxx
client_id: hassio-mqtt-client
The MQTT Server & Web Client config looks like…
{
"ssl": false,
"certfile": "fullchain.pem",
"keyfile": "privkey.pem",
"broker": true,
"allow_anonymous": false,
"mqttusers": [
{
"username": "robshamqtt",
"password": "xxxxxxxxxxx",
"readonly": false,
"topics": [

]
}
]
}
…and the ESPHome units MQTT config, attempting to publish sensor values, looks like…
mqtt:
broker: 192.168.1.120:1884
username: "robshamqtt"
password: "xxxxxxxxxxxx"
client_id: hassio-mqtt-client

So, I’ve absolutely no idea why I’m getting the above error and if anyone out there knows then please get back to me.
Thanks…
