Help needed with automation and json template warning

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.

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

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 ?

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

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

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.

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.

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

Thanks

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

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…

backtrack · May 5, 2021, 3:59pm

I answer my own question just to help someone else who could face the same problem. Not knowing how else to get rid of all those warning I just deleted the device from the mqtt integration and then rebooted it to let it reconnect to HA … it appears for now that the warnings are gone

steeveno · May 6, 2021, 7:22am

FYI, I read somewhere that rolling back to Mosquitto 5.1 will help resolve the issues, in my case it didn’t change anything…

dbrunt · July 27, 2021, 6:59pm

With Zigbee2MQTT, you need to add these settings to disable it’s legacy code which causes HA 2021.4 and newer to spew warnings.

advanced:
  legacy_api: false
device_options:
  legacy: false

Refer to Still showing " Template variable warning " in HA with Z2M 1.19.1 · Issue #7824 · Koenkk/zigbee2mqtt (github.com)

Olivier974 · November 27, 2021, 9:13am

i have add those options in the AddOn config Zigbee2Mqtt but no changes…

Perhaps a stupid question : its wrote to add thoses lines in “configuration.yaml”, it is under the AddOn Zigbee2Mqtt configuration or under HassOs /config/configuration.yaml ???

Thanks…i m lost…

thanks a lot @dbrunt !

i just realise that this config is different from the AddOn config…i am used to modify the config in the AddOn not under “config/Zigbee2mqtt/configuration.yaml”…

Is it normal that my config there is different to the AddOn’s one please?

EDIT : i put the 2 option legacy but still the warning “Template variable warning: ‘dict object’ has no attribute ‘voltage’ when rendering ‘{{ value_json.voltage }}’” is still there.

dbrunt · November 29, 2021, 2:26am

That is what I see also but I cannot comment about the differences. I too am using the add-on…
