Hey everyone,
Still trying to get the hang of HA, I’ve read through the documentation but am still having trouble defining a template to pull an attribute of a sensor. So I have this sensor:
And I am trying to pull out the WNow attribute. I’ve set up this template, but it responds with null.
{{ state_attr('sensor.solar_api_productions', 'WNow') }}
Any idea’s what I am doing wrong?
Look at the sensor in the Developer Tools → States menu. What is shown in the right hand column?
Also does this really have an “s” on the end?
sensor.solar_api_productions
Which integration was used to create this sensor?
I used Restful to pull from my enphase system using an API call.
Here is the code I used to generate that:
sensor:
- name: "Solar API Production"
unique_id: solar_api_production_production
value_template: "{{ value_json.value }}"
json_attributes_path: $.production[1]
json_attributes:
- wNow
- whLifetime
- varhLeadLifetime
- varhLagLifetime
- vahLifetime
- rmsCurrent
- rmsVoltage
- reactPwr
- apprntPwr
- pwrFactor
- whToday
- whLastSevenDays
- vahToday
- varhLeadToday
- varhLagToday
Without seeing the raw returned data I am guessing but if there really is a key called “value” you can’t access it like that. In the context of the template value means the entire raw value. You have to do this to access a specific key called “value”:
value_template: "{{ value_json['value'] }}"
That should fix the state, and maybe then the attributes will be accessible too.
Okay so I fixed the state by just hardcoding the value “OK” in there for the state:
sensor:
- name: "Solar API Production"
unique_id: solar_api_production_production
value_template: "{{ "OK" }}"
json_attributes_path: $.production[1]
So the state is now reading OK, and the attributes still have their value, but the template still is reporting null.
Here is a copy of the API output from postman:

Btw thank you for your help.
This:
Should be:
{{ state_attr('sensor.solar_api_productions', 'wNow') }}
(lower case “w”).
Sorry for the late reply, thats frustrating. But thank you!
