I've attached a syslog extract showing where weewx crashed. it seems that
"volt" is an invalid unit for my topic. i don't know why but for now I
commented out that topic and its parameters. Now, weewx will continue
running when subscribe is enabled, but subscribed topics are not being
posted to the database. Here is the first topic in weewx.conf:
# The first topic
# MQTT Topic
[[[snow/snowDepth]]]
# MQTT name
[[[[snowDepth]]]]
# weewx name
name = snowDepth
ignore = false
contains_total = false
conversion_type = float
units = inch
I used a terminal to publish "6" to snow/snowDepth on Mosquitto. Another
terminal window command to subscribe to snow/snowDepth received the "6" but
the database entries for snowDepth are null. Is this configuration of
topics still not correct. Thanks.
