Elastic Search filter query for null values

Question

I am trying to write a query where it searches in elastic that if fields is null then filter it out. In my case if both battery temperature and temperature value is null then remove it from the bucket, if one value is null then no need to filter.

Above query is used and in some cases both temperature and battery values are coming null which I need to remove from the buckets.

      ],
      "filter": [],
      "should": [],
      "must_not": []
    }
  }
}

query should get asset 1 and 3 but in my case i am getting asset 2 which i need to filter.
