Sensor attribute from list

ESPHome
1

So, wondering if there’s a way to configured a homeassistant sensor in esphome to pull attributes from a list? For a weather component I have a state, plus a long list of attributes, like such:

temperature: 90
humidity: 17
ozone: 286.49
pressure: 24.96
wind_bearing: 294.94
wind_speed: 6.622
visibility: 10
forecast: 
- datetime: '2022-06-18T00:00:00+00:00'
  temperature: 91
  precipitation: null
  condition: cloudy
- datetime: '2022-06-18T01:00:00+00:00'
  temperature: 90
  precipitation: null
  condition: cloudy

Wondering how I could pull the second temperature, and 3rd, and so on. Normally I’d use jq or yq on the command line, but that’s not possible here. Any idea?
Hopefully I don’t have to create a template sensor for each, in home-assistant.

You can get attributes in to homeassistant: Home Assistant Text Sensor — ESPHome

However I am not sure how to specify a nested attribute. If it is possible, perhaps something like [1].temperature, [2].temperature.

Hmm, good guess, but that didn’t work.

  in "/config/edsw.yaml", line 80, column 5:
      - platform: homeassistant
        ^
expected <block end>, but found '<scalar>'
  in "/config/edsw.yaml", line 82, column 19:
        attribute: [1].temperature
                      ^

Any other ideas?

If I had to guess it would be forecast[1].temperature because forecast is the name of the array.

5

hmm, good guess but still no love.
Tried forecast[1].temperature & forecast.[1]temperature.

For once in my life I actually wish the output was in JSON.

6

What if you only do forecast? do you get the whole array to the other side so you can parse it there?

7

Hm, that’s an option, wondering how I would parse out the individual hourly forecasts from that.

Wonder if a solution was found. :man_shrugging: I now also am trying to do similar to go through attribute sub keys / values to list on my esphome display.

did you find time to go look at the documents while also wondering? Seems like a good place to start. Mostly because it specifically talks about importing attributes and provides an example for importing a sensor attributes…

It works just fine with just adding one attribute from an entity. The question I had here was if the attribute had sub keys and you would
I have an energy entity. It has a lot of attributes some of them like the example below have sub key values like hour, price. Would like to enumerate over them somehow.

today_min:
hour: “2024-03-06T03:00:00+01:00”
price: 2.1
today_max:
hour: “2024-03-06T18:00:00+01:00”
price: 3.69

I was able to find quite a bit with a couple quick searches. They’re all pretty old going back to 2020,21’ and IDK if they still work. It sounds like the quickest/simplest way would be to break the attributes out of the sensor in HA and then make each of them their own sensor that you import into esphome.
