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

11

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.

21

It looks like the names have changed again, possibly due to the WeeWX 5.x update. Or at least ThomDietrich’s very useful config doesn’t work any more with the current version. Here’s a partial list of what currently works, if it’s useful I’ll post the full thing.
