I’m trying to set up a influxdb sensor, but no matter how I do the configuration, I get this error in home assistant:
Traceback (most recent call last):

simplejson.errors.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

The config is:

- platform: influxdb
    host: 192.168.2.56
    port: 443
    ssl: true
    verify_ssl: false
    username: dario
    password: !secret influxdb_password_2
    queries:
      - name: power usage it systems
        unit_of_measurement: W
        value_template: '{{ value | round(1) }}'
        group_function: last
        where: '"host" = ''srv-ubn-services-1'''
        measurement: '"ups"'
        field: ups_load_perc
        database: telegraf_data

Any idea what I’m doing wrong?
