tldr:
Try the following.
Remove the contains_total and if the [Accumulator] section does not exist,
add the following. If it exists, just add the [[kwh]] subsection. Note
that [Accumulator] is a ‘ top level’ section.
[Accumulator]
[[kwh]]
extractor = sum
Background:
When running as a service, MQTTSubscribe has no control over the arrival of
the MQTT data nor the loop interval. It leverages WeeWX accumulator
functionality to manage when multiple MQTT payloads have arrived since the
last loop packet generation. The default accumulator extractor is average,
the configuration setting above will override this, setting it to sum.
The idea is to treat the loop packet like a ‘mini archive’. I haven’t fully
vetted this, so I will be very interested in how it goes.

ps. I think you should be able to remove the conversion_type because the
default is float.
