Help needed with automation and json template warning

sineverba · April 8, 2021, 9:06am

Hi all!
I have these automations (created about 3 months ago via web interface)

- id: '20210406174401'
  alias: SWITCH 1 - SINGOLO
  description: ''
  trigger:
  - platform: device
    domain: mqtt
    device_id: 145b5920014fcf022d0383fe02450fb8
    type: action
    subtype: single
    discovery_id: 0x00158d00066f963e action_single
  condition: []
  action:
  - service: light.turn_on
    target:
      entity_id: light.01107f
  mode: single
- id: '20210406174400'

    target:
      entity_id: light.01107f

Device is a Xiaomi WXKG11LM 1 button, connected via Zigbee2Mqtt.

From 2021.04.0 I have these warning in logs:

Logger: homeassistant.helpers.template
Source: helpers/template.py:1335
First occurred: 10:59:46 (2 occurrences)
Last logged: 10:59:46

Template variable warning: 'dict object' has no attribute 'click' when rendering '{{ value_json.click }}'
Template variable warning: 'dict object' has no attribute 'action' when rendering '{{ value_json.action }}'

How can I fix them? Thank you

Wait for the update of Zigbee2MQTT In the mean time, just ignore them, they are only warnings.

gabrielmiranda · April 13, 2021, 6:44am

Same problem here. But I noticed a certain delay on the device because of that.

Got the same but related to the upgrade to 2021.4.3.
The error seems to be exactly the same, same place in template.py, but a template I’ve done myself. The template has been working for a couple of years (until upgrade to 2021.4.3). The issue occurs every 30 seconds. I dunno if there are relations, but my HA installation seems to crash once a day. It cannot fetch data for my integrations (e.g. Miele, REST, Uhomeupnor, basically everything). Think that error is related to some sort of overflow of all the ‘dict object’ warnings… but that’s just a guess.
My exact error is just like yours:

2021-04-13 19:44:45 WARNING (MainThread) [homeassistant.helpers.template] Template variable warning: 'dict object' has no attribute 'sonnen' when rendering '{{ value_json.sonnen }}'

For kicks my template is here:

  #PV panels (Sonnen)
  - platform: rest
    name: JSON sonnen
    json_attributes:
      - Consumption_W
      - GridFeedIn_W
      - Production_W
      - USOC

    value_template: '{{ value_json.sonnen }}'
  - platform: template
    sensors:
      sonnen_consumption:
        friendly_name: 'Consumption W'
        value_template: '{{ states.sensor.json_sonnen.attributes["Consumption_W"] }}'
        unit_of_measurement: W
      sonnen_gridfeedin:
        friendly_name: 'Grid feed-in W'
        value_template: '{{ states.sensor.json_sonnen.attributes["GridFeedIn_W"] }}'
        unit_of_measurement: W
      sonnen_production:
        friendly_name: 'Production W'
        value_template: '{{ states.sensor.json_sonnen.attributes["Production_W"] }}'
        unit_of_measurement: W

        friendly_name: 'State of Charge %'
        value_template: '{{ states.sensor.json_sonnen.attributes["USOC"] }}'
        unit_of_measurement: "%"

Hope someones looks at this issue Thanks

I use Home assistant with Zigbee2mqtt-AddOn
Current version: 1.18.2-1

I got following Warnings in Homeasistant Log:

...

2021-04-14 09:24:35 WARNING (MainThread) [homeassistant.helpers.template] Template variable warning: 'dict object' has no attribute 'linkquality' when rendering '{{ value_json.linkquality }}'
2021-04-14 09:24:36 WARNING (MainThread) [homeassistant.helpers.template] Template variable warning: 'dict object' has no attribute 'linkquality' when rendering '{{ value_json.linkquality }}'
2021-04-14 09:24:43 WARNING (MainThread) [homeassistant.helpers.template] Template variable warning: 'dict object' has no attribute 'requested_brightness_level' when rendering '{{ value_json.requested_brightness_level }}'
2021-04-14 09:24:43 WARNING (MainThread) [homeassistant.helpers.template] Template variable warning: 'dict object' has no attribute 'requested_brightness_percent' when rendering '{{ value_json.requested_brightness_percent }}'
...

They are throwing with different variables (equested_brightness_percent,requested_brightness_level ,linkquality etc.)
They were starting after update to:
core-2021.4.4

I guess, Hassio changed exception handling.
I had an if/else Block, which worked up to core-2021.4.4. Then it throws same Warning

        {% if  trigger.event.data.room  %}
            {{ trigger.event.data.room }}
        {% else %}
            {{ trigger.event.data._intent.siteId }}
        {% endif %}

I changed it to:

        {% if  trigger.event.data.room is defined  %}
            {{ trigger.event.data.room }}
        {% else %}
            {{ trigger.event.data._intent.siteId }}
        {% endif %}

That works and no warning any more
I guess, after core-2021.4.4, all variables needs to be checked.
I hoped that helps

ZkiiFreak · April 14, 2021, 4:05pm

Hmmm. Changed
value_template: '{{ value_json.sonnen }}'
to
value_template: 'OK'

Seems to have removed the errors from the log at least. I hope it also brings back stability…

petro · April 14, 2021, 4:11pm

This is covered in the breaking changes and it even provides a solution. Check out the template section in breaking changes.

value_template: '{{ value_json.sonnen | default }}'

briis · April 16, 2021, 11:54am

I saw that, but I have no clue where to look to fix this. If I look at my log I see this as an example:

Logger: homeassistant.helpers.template
Source: helpers/template.py:1335 
First occurred: 1:26:44 PM (55 occurrences) 
Last logged: 1:48:05 PM

Template variable warning: 'dict object' has no attribute 'led_indication' when rendering '{{ value_json.led_indication }}'
Template variable warning: 'dict object' has no attribute 'energy' when rendering '{{ value_json.energy }}'
Template variable warning: 'dict object' has no attribute 'temperature' when rendering '{{ value_json.temperature }}'
Template variable warning: 'dict object' has no attribute 'voltage' when rendering '{{ value_json.voltage }}'
Template variable warning: 'dict object' has no attribute 'current' when rendering '{{ value_json.current }}'

This does not tell what entity is reporting the error, so I have no clue where to go and fix it. My guess is, that this is Zigbee2mqtt entity or entities but I have many entities reporting temperature, and voltage as an example.

petro · April 16, 2021, 11:55am

It’s all handled on the zigbee2mqtt side’s discovery. I don’t know how that works, so I can’t help you.

JohannCR · April 16, 2021, 12:19pm

I can add to this discussion that in my case I’ve scoured all my files (config, automations, sensors, etc.) and cannot find some templates mentionned in the logs…
All the templates I use I have corrected using default value, but there seems to be some entities defined elsewhere (inside plugins ?).
Do we have to wait for the developpers of every plugins to fix them ?

petro · April 16, 2021, 12:25pm

Yes, if they are provided by MQTT discovery and you didn’t manually configure them.

hollosipeti · April 17, 2021, 3:11pm

For me, it is caused by Zigbee entities. Zigbee2mqtt.

U.R.A.M.Q.T.T · April 21, 2021, 11:55pm

Is anyone else experiencing a breakdown of functionality for Automations using any z2m entities after 2021.4? All devices can be used from HA directly so communication looks fine.

The Release Notes state that this ‘dict object’ message is a just a warning so I’m not sure if this is the cause or something else. System was rock solid before the upgrade.

I’d upgraded z2m to 1.18.2 at the same time as doing HA to 2021.4; so every possibility that z2m is the real culprit.

septillion · April 22, 2021, 9:15am

Do you still have triggers with a click instead of an action? I think they dropped “click” by default as it was already deprecated some time ago in favour of “action”.

U.R.A.M.Q.T.T · April 22, 2021, 9:55am

All using Action, thanks.

septillion · April 22, 2021, 10:12am

Then I don’t know. I would say, do a full restart and if you still have problems go into detail of one of the automations that does not work. For further help I would open a new topic though.

roma_pop · April 25, 2021, 6:35am

Hi there,
Could you please help and mention where exactly you put this exceptions in HA or Zigbee2mqtt part ?

Thanks

kaykoch · April 26, 2021, 10:44am

General:

The Warning comes because of a undefined variable from zigbee2mqtt. If I understand well, this is already fixed in the dev and will be in the next minor release in May.

Template rendering warnings in latest Home Assistant beta for dictionary missing attribute

opened 02:57PM - 07 Apr 21 UTC

closed 03:01PM - 12 Apr 21 UTC

problem

## What happened Starting in Home Assistant `2021.4.0` templates referencing …an attribute of a dictionary which does not exist generate a warnings like this: ``` 2021-04-07 15:05:31 WARNING (MainThread) [homeassistant.helpers.template] Template variable warning: 'dict object' has no attribute 'action' when rendering '{{ value_json.action }}' ``` I traced these errors back to the source and its a result of the discovery payload sent by Z2M to Home Assistant. The discovery payload sends this as the template to use to parse the value for a sensor out of the JSON payload: ``` value_template: '{{ value_json.action }}' ``` For devices which don't report all their attributes all the time (ex. remotes that report an action on button press) this creates a problem. Anytime a payload is received without the attribute a warning is created. This warning will become an error and a failure starting in `2021.10` (see https://github.com/home-assistant/core/pull/48140 ) Fortunately there appears to be a relatively easy fix. If the discovery template is changed to this then all the errors should go away: ``` {{ value_json.action | default('', true) }} ``` It's a bit strange to always default to `''` even for numeric attributes but this is what was occurring before. Returning `None` as the default also works and does not generate a warning (I tested). That might be more correct but not sure if that has any other consequences downstream. The `true` is so it only appllies the default if things truly don't exist and not just if they evaluate to `false` (see [default](https://jinja.palletsprojects.com/en/master/templates/#default)). ## What did you expect to happen Not to see a warning for attribute did not exist ## How to reproduce it (minimal and precise) The error above is showing what can occur if you have a remote type device such as [Philips 929002398602](https://www.zigbee2mqtt.io/devices/929002398602.html) that checks in all the time with basic attributes like battery and linkquality and includes an action on button press. You can also create an error like this with any device by doing the following: 1. Proceed with Home Assistant discovery for the device 2. Use `filtered_attributes` to tell Z2M to stop reporting one or more attributes 3. See you get warnings for the sensors trying to read an attribute that is no longer being reported in This creates errors like this: ``` 2021-04-06 21:24:44 WARNING (MainThread) [homeassistant.helpers.template] Template variable warning: dict object has no attribute voltage ``` I realize in this particular use case the right fix is just to disable the sensor in Home Assistant (which is what I did). But I don't know all the devices that report some attributes occaisionally, figured it would be good to have a way to simulate that with any device. ## Debug info Zigbee2MQTT version: 1.18.2 Home Assistant version: 2021.4.0b5 Adapter hardware: Conbee II Adapter firmware version: 0x264a0700

My Code:

I changed the

{% if trigger.event.data.room %}

to:

{% if trigger.event.data.room is defined %}

in every automation, where I need a special room which is not necessarily given or the the satellite name, which always exists.

Hi to everybody, I’m experiencing the same log warnings which in my case are related to mqtt messages sent by a “tasmotized” PZEM which I mainly use in order to compare the power produced by the solar panels and the in house power consumption. Well no problem until the last HA upgrade while now I’m bombarded with those messages although the power values shown by the PZEM seem to be reasonably correct. I read about the “breaking changes” concerning the templates but I wouldn’t know how to address the problem especially because the mqtt connection between the PZEM and HA is “behind the scene”. Anyone having an idea? Thank you
Federico

Is click really deprecated? I used it everywhere and could not find any info regarding that, also now when searching for it…
