Vince,
Sorry for the delay, I missed your post on my phone whilst away from home.
Status as follows: -
The new Ecowitt MQTT protocol is publishing to broker with no problem and I can
see the data arriving in the broker browser.
In weewx.conf I have this: -
[MQTTSubscribeDriver]
driver = user.MQTTSubscribe
host = broker.mqtt.cool
port = 1883
keepalive = 60
username = None
password = None
binding = loop
[[topics]]
unit_system = US
[[[ecowitt/1C6920E3A8F3]]]
subscribe = True
ignore = False
[[[[message]]]]
type = keyword
keyword_delimiter = "&"
Then, extract from journal log: -
