MQTT - Dict Object has no attribute

[koying (Chris B)]

I don’t get it.

You are obviously using the {{ value_json.linkquality }} template somewhere. Replace it with the lines above, which are also a template, just more elaborate.

e.g.

value_template: {{ value_json.linkquality }}

→

value_template: >-
  {% if "linkquality" in value_json %}
    {{ value_json.linkquality }}
  {% else %}
    0
  {% endif %}

[KCYeoh (Yeoh)]

No…no… I’m not using it. It was the zigbee2mqtt…some of the devices are broadcasting a null attributes and cause the HA capture this as warning.

[koying (Chris B)]

Oh, the MQTT discovery part?
Yeah, Z2T issue, then.

Can someone help me out on supprression this warning? I have no idea. Thank you.

@duceduc

{% set holiday =  value_json.MAJOR_JP.static[ today ] %}
{% if holiday | trim == "" %}

You’re trying to access an element of your dict without checking if the key exists.
If it doesn’t, you get the warning
Rather than the above, do something like

{% if today in value_json.MAJOR_JP.static %}

Hi. I am getting this error now.

error:

@duceduc

{{ holiday }}

You using it while not initialized.
Use set holiday = '' or whatver before the if.

[duceduc]

ok. sorry. I have edit for the following and it looks like the original error has came back.

Same problem here:

Im using a WXKG02LM with zigbee2mqtt

[Johanvh (Johan Van Hoorde)]

Same error but not related to Z2M. I followed this ‘tutorial’ to switch the screen on/off from my tablet: Fully Kiosk Browser
Since this is configured, and it works great, I have below error:

Logger: homeassistant.helpers.template

According the tutorial my sensors.yaml contains:

  - platform: rest
    name: foo
    json_attributes:
      - batteryLevel
      - kioskMode
      - screenBrightness

I want to get red of this error but don’t know how

Same problem (not Z2M). It’s happening with several sensors from a raspberry pi monitor plugin I have:

[ilbagatta]

The same for me…

I used this GitHub - Sennevds/system_sensors: Logging of system sensor specific for the RPI and sending them to a MQTT broker for monitor other rpi.

I started the script with load_1m, load_5m and load_15m monitor and all worked.
Then, i removed this 3 sensors, and started to log this error:

2022-03-13 00:58:53 WARNING (MainThread) [homeassistant.helpers.template] Template variable warning: 'dict object' has no attribute 'load_1m' when rendering '{{value_json.load_1m}}'

I think that MQTT has them saved somewhere… or not?

[uiguy]

I have a Tekelek sonic tank level monitor (Tek 766) connected over LoRaWAN and delivering payloads via MQTT into Home Assistant.

It send updates every 6 hours or so (which is configurable) however sending the battery state is not as easily configurable to synchronise with the level payloads.

This means that sometimes the Battery reading is not there and then these errors occur. This manifests in the UI where the battery percentage goes from it real reading (83%) to 0%.

Is there no way in Home Assistant that the battery sensor simply does not update when there is no reading? I don’t mind the errors in the logs, it is the resulting inaccurate readings that is the trouble…

[bohrgu]

I hope that it will help some of you but this is how I had it working in my case (Zigbee Bridge from Sonoff flashed with Tasmota):

mqtt:
  sensor:
    - state_topic: "tele/tasmota_F1234F/SENSOR"
      name: "Bedroom_Temperature"
      device_class: temperature
      value_template: "{% if value_json['ZbReceived']['0x123A'].Temperature is defined %} {{ value_json['ZbReceived']['0x123A'].Temperature }} {% else %} {{ state('sensor.Bedroom_Temperature') }} {% endif %}"
      unit_of_measurement: "°C"
    - state_topic: "tele/tasmota_F1234F/SENSOR"
      name: "Bedroom_Humidity"
      device_class: humidity
      value_template: "{% if value_json['ZbReceived']['0x123A'].Humidity is defined %} {{ value_json['ZbReceived']['0x123A'].Humidity }} {% else %} {{ state('sensor.Bedroom_Humidity') }} {% endif %}"
      unit_of_measurement: "%"

In my case my Zigbee sensors return only one value at a time, either ‘Temperature’ or ‘Humidity’, but inside the exact same JSON topic from my bridge, and when I had one the other was always reset inside HA.
Here I use “is defined” to check the presence of the value and set the current state if it’s not defined, this way when I get ‘Humidity’ it doesn’t reset the ‘Temperature’ value to “unknown”

Here are two example topics I got from my bridge (to explain the issue):

tele/tasmota_F1234F/SENSOR = {"ZbReceived":{"0x123A":{"Device":"0x123A","Name":"Bedroom_Sensor","Temperature":19.77,"Endpoint":1,"LinkQuality":58}}}
tele/tasmota_F1234F/SENSOR = {"ZbReceived":{"0x123A":{"Device":"0x123A","Name":"Bedroom_Sensor","Humidity":60.48,"Endpoint":1,"LinkQuality":52}}}

My solution is based on the following pages:

Missing value with mqtt (only last data set is shown?)

ok. i found the solution myself. there is only one topic which is parsed by HA, and then search for keywords. if the keyword can not be found it’s set to undefined/empty. jinja2 doc states: If a variable or attribute does not exist, you will get back an undefined value. What you can do with that kind of value depends on the application configuration: the default behavior is to evaluate to an empty string if printed or iterated over, and to fail for every other operation. so all i had do wa…

Template for testing to see if a json key exists in MQTT topic

And I think I stumbled upon my answer: “3. You must surround single-line templates with double quotes ( " ) or single quotes ( ' ).” Since the quotes are required for single line templates if the same line is put in a multi-line template and surrounded by quotes it apparently acts completely differently.
