Must I do something special to push the LOOP records more frequently
through MQTT? I've imported the Paho MQTT Python library and the loop
record is being pushed at the ARCHIVE interval, which is also confirmed
with MQTT Explorer. I've seen timestamp of 15:45:27, 15:40:10, 15:35:29 and
15:30:20 for the 'acurite/loop' topic. This is what I have in the
weewx.conf file for MQTT
[[MQTT]]
server_url = mqtt://username:password@hostname:1883/
topic = acurite
unit_system = METRIC
retain = true
Is there something missing?
Thanks for your help
