I've been looking at Rich Bell's nested json example here:
https://github.com/bellrichm/WeeWX-MQTTSubscribe/wiki/json-example
He shows a first topic, second topic, third topic, etc.
If you include the time, I think this BMP280 has 5 topics? (Time,
Temperature, Pressure, PressureUnit, TempUnit)
Here's what I've got now: in my weewx.conf file:
# The message handler to use
[[message_callback]]
# The format of the MQTT payload.
# Currently support: individual, json, keyword
# Must be specified.
type = json
# When the json is nested, the delimiter between the hierarchies.
# Default is _.
flatten_delimiter = "_"
# The topics to subscribe to.
[[topics]]
# Units for MQTT payloads without unit value.
# Valid values: US, METRIC, METRICWX
# Default is: US
unit_system = METRIC
use_server_datetime = True
ignore_start_time = True
ignore_end_time = True
[[[first/topic]]]
# The incoming field name from MQTT.
[[[[Time]]]]
ignore = true
[[[second/topic]]]
[[[[BME280_Temperature]]]]
# The WeeWX name.
# Default is the name from MQTT.
name = appTemp1
units = degree_C
[[[[BME280_Pressure]]]]
# The WeeWX name.
# Default is the name from MQTT.
name = barometer
units = hPa
[[[third/topic]]]
# The incoming field name from MQTT.
[[[[PressureUnit]]]]
ignore = true
[[[fourth/topic]]]
# The incoming field name from MQTT.
[[[[TemperatureUnit]]]]
ignore = true
