fyi - here's an example MQTTSubscribeService section with annotations in
case anybody has interest. See the attachment for which sensors are
handled. Should be obvious.
Items marked FIXME aren't directly mapped to weewx db elements in this
example, but some light editing would be needed regardless to match your
setup of course.....
Lastly - MQTT is now supported on the GW1200 gateway and WS3802 console if
you update the firmware, so it seems like Ecowitt is adding support to
older models of their gear as time passes...

# This is an example section mapping ecowitt MQTT payload to weewx db items
# for hardware consisting of:
#
# GW1200 gateway running firmware V1.4.0
# WH32 outside t+h sensor
# WH31 additional inside t+h sensors (id 1-5)
# WH51 soil moisture sensor
# WH34S soil temperature sensor
# WH40BH tipping rain gauge set as primary rain sensor
# WS85 haptic/piezo rain/wind sensor set a secondary wind sensor
#
# items marked 'FIXME' still need to be mapped to weewx db elements or ignored
#
# this configuration ignores by default to be able to handle future firmware
# updates that add new MQTT payload content, but also is set to stop weewd
# on validation errors to handle typos, duplicate items, etc. that might be
# later added in by user error
#
# this example does no use tls nor MQTT username/password although both are
# supported by the driver
