Sensor.webhook_temperature: UndefinedError: 'dict object' has no attribute 'temperature'

Configuration

guys & gals I admit failure on this one.

I’m trying to extract a simple temp value from a json file webhook. data is coming through fine. However my webhook is failing to extract the right information from the JSON file:

{“event”:{“eventId”:“c3v8minimbf5a5g12mj0”,“targetName”:“projects/bskjodneanog00f76kf0/devices/bjeis9e7gpvg00cjoapg”,“eventType”:“temperature”,“data”:{“temperature”:{“value”:27,“updateTime”:“2021-07-26T10:15:04.644000Z”,“samples”:[{“value”:27,“sampleTime”:“2021-07-26T10:15:04.644000Z”}]}},“timestamp”:“2021-07-26T10:15:04.644000Z”},“labels”:{}}

My template is:

template:

  • trigger:
    • platform: webhook
      webhook_id: sensor_tempdt
      sensor:
    • name: “Webhook Temperature”
      state: “{{ trigger.json.temperature[‘value’] }}”
      unit_of_measurement: °C

Seems like every combination I use I can’t get the value to register. Any and all help is appreciated.

Please edit your post and format your pasted config and data as per point 11 here.

Anyway, I pasted the json data you provided into the left side of this site: https://jsonpathfinder.com/

Then I had to replace all the fancy quotes “” with straight quotes "" in a text editor and try again (because you did not format your data as above).

Then I drilled down on the right hand side to obtain this path (at the top of the right hand side column):

x.event.data.temperature.value

So you need:

state: "{{ trigger.json.event.data.temperature['value'] }}"

The value on the end has to be in square bracket notation as that word has special meaning in templates (but you already had that bit sorted).
