WeeWX, MQTT and how to import Data

Third party integrations Floorplan
1

Ladies, Gents,

i´m not a newbee, but 52 y old and not a skilled mqtt pro.
system: raspi 3b+ with 120gb ssd: hass core 0.112.2 OS 4.10 mosquitto broker
weewx on another raspi.

currently i´m asking the weewx server via mqtt broker for new weather data. log:

1594996516: New connection from 192.168.0.15 on port 1883.
1594996516: New client connected from 192.168.0.15 as weewx_36f5aed1 (p2, c1, k60, u’xxxxxxx’).

1594997121: Client weewx_d92fbd1c disconnected.

so far, so good, but where are the data? how can i integrate the data into hass.io?
i´ve checked with the mqtt explorer, if there are the data and voila
mqtt

ok, but how to subscribe the wx-variables and how can i integrate them?

any help is very appreciated,
greez michl

Use the MQTT sensor.

Great! Thank you @Burningstone!

Is there a way to reduce the number of decimals?

4

You can round the result in the value_template part of the sensor. Can you show your current working code please?

this is the part from configuration.yaml

mqtt sensor

sensor:
- platform: mqtt
name: “OutTemperature1”
state_topic: “weather/outTemp_C”
unit_of_measurement: ‘°C’

Please read this topic, especially point 11 regarding the correct formatting of code in the forum.

You can use a value_template to round your value.

Try this:

sensor:
  - platform: mqtt
    name: “OutTemperature1”
    state_topic: “weather/outTemp_C”
    unit_of_measurement: ‘°C’
    value_template: "{{ (value | round(2)) | float }}"

I’m not sure if the last float filter is needed, you can probably remove it, can’t test at the moment.

Thank you @Burningstone for help and hints regarding correct formatting.
and no problem, i´ll play around and will inform if this thing works.

works like a charme.
thp-display

i had to adapt the quotation marks and reduced to 1 decimal, now this is working fine:

sensor:
    - platform: mqtt
      name: "OutTemperature_101"
      state_topic: "weather/outTemp_C"
      unit_of_measurement: '°C'
      value_template: "{{ (value | round(1)) | float }}"

Thx for helping a silversurfer :wink:

Hello all
I am trying to bring this example into the MQTT format for version 2022.12.0.
Unfortunately I have absolutely no idea how and all attempts to bring the upper into a mqtt.yaml fail.

I hope you can help me with this as I don’t really understand the new format.

Many thanks in advance
Guido

Hey, was confused as you are talking about changes in 2022.12. I believe these changes came some releases ago BUT the old format was deprecated with 2022.12.

Anyhow, it’s not that complicated of a change. I’ve just updated my post above with the working weewx.yaml configuration. Hope it works for you as well!

12

Hello ThomDietrich

Thanks for the change

I was able to save the file mqtt.yaml successfully with your information.
However, I still get an error message.
I have this entry in configuration.yaml:

mqtt: !include mqtt.yaml

and I get the following error message:

Invalid config for [mqtt]: [mqtt] is an invalid option for [mqtt]. Check: mqtt->mqtt->mqtt. (See /config/configuration.yaml, line 10)

Do I have to make another entry in configuration.yaml?

13

You need to learn about packages. I always felt that the concept and a base configuration should be part of the default configuration! Anyhow, please read here: Packages - Home Assistant

  1. In your configuration.yaml add:
    homeassistant:
  packages: !include_dir_named packages
  2. Create the folder packages
  3. Create and fill packages/weewx.yaml with the content above.

In parallel you can create all kinds of yaml files, for topics. Here is a random example I found via google: home-assistant-config/packages at master · aneisch/home-assistant-config · GitHub

14

Thank you for your help with my problem.
Everything is now working as it should.

I wish you all a merry and healthy christmas.
Guido

Hello,

Is it possible to send the MQTT section of your weewx.conf file ?
I have problems with reading the values ?

Grtz

16

hi, this is the section in the weewx.conf

[[MQTT]]
    server_url = mqtt://username:[email protected]:1883
    topic = weather
    unit_system = METRIC
    retain = True

username & password have to be defined in the config of the mosquitto broker @homeassistant in the config tab. hope it helps.

Have Problems to receive data of my weewx station.

i installed the addon in weewx and add this to my config:

    [[MQTT]]
        server_url = mqtt://mqtt_user:[email protected]:1883
        topic = weather
        unit_system = METRIC

i also added this to my configuration.yaml in HA.

Hello @noxx,

First thing that immediately catches my eye: in MQTT Explorer we can see windSpeed_kph but you are trying to subscribe to windSpeed_kmh in HA. Please check your definitions.
