Hello,

happy new year to all!

I am getting the following error message:

the part of weewx.conf looks like:

 

[MQTTSubscribeDriver]

    driver = user.MQTTSubscribe

 

    port = 1883

 

    log = true

    keepalive = 60

    [[message_callback]]

        type = json

 

    # The topics to subscribe to.

    [[topics]]

        unit_system = METRIC

 

        [[[weather-hp1000/inTemp]]]

            # The WeeWX name.

            # Default is the name from MQTT.

            name = extraTemp12

            conversion_type = None

            units = degree_C

 

        [[[weather-hp1000/UV]]]

and this is how the part looks in the other weewx installation:

 

    [[MQTT]]

        server_url = mqtt://xxxxxxxxxxxxxxxx

        topic = weather-hp1000

        unit_system = METRIC

        binding = archive, loop

        aggregation = individual

        append_units_label = false

Can anyone tell me where the error is in my configuration.

Thanks...

Michael

Looks like the MQTT payload is of type 'individual'.  Try setting
    [[message_callback]]
        type = individual
instead of 'type = json'
