I have successfully used mqtt when running weewx on a raspberry pi. I am
now running weewx under docker on a more powerful pi4. The mqtt settings
that worked originally now give the following error.
ValueError: Port could not be cast to integer value as '1883 ' - full
error log below
1 There were no errors when paho-mqtt was installed.
2 weewx.conf entries
[[MQTT]]
enable = True
log_success = False
server_url = //broker.emqx.io:1883 /
topic = xxxx/yyyyyyy
unit_system = METRIC
aggregation = aggregate
binding = archive, loop
[[[inputs]]]
[[[[dayRain]]]]
units = mm
[[[[rainRate]]]]
units = mm_per_hour
3 port 1883 on the container is linked to port 1883 on the host
Can anyone help me to resolve this please?
Thanks
