Similarly I modify the sensors in home assistant with YAML:
################################################
# Sensors
################################################
mqtt:
sensor:
- name: weewx_datetime
state_topic: "weather/loop"
value_template: |-
{% if value_json.dateTime is defined %}
{{ value_json.dateTime | float }}
{% endif %}
- name: weewx_temperature
state_topic: "weather/loop"
unit_of_measurement: "°F"
value_template: |-
{% if value_json.outTemp_F is defined %}
{{ value_json.outTemp_F | round(1) }}
{% endif %}
