Is it possible to push batch telemetry with the mqtt connector ?

[trya2l]

Hello,

I use version 3.7.3 and I'd like to push timeseries data as batch, through the mqtt connector.

I'm able to send an individual entry

{"ts":1750447024166,"values":{"prediction":4}}

but I cannot visualize arrays

[
  {"ts":1750446004037,"values":{"prediction":5}},
  {"ts":1750446304037,"values":{"prediction":3}},
  {"ts":1750446604037,"values":{"prediction":3}},
  {"ts":1750446904037,"values":{"prediction":4}},
  {"ts":1750447204037,"values":{"prediction":5}}
]

However, they are correctly converted by the gateway. I can see it in the logs.

[json_mqtt_uplink_converter.py] - json_mqtt_uplink_converter convert - 60 -
[ConvertedData(deviceName=model, deviceType=default, telemetry=[TelemetryEntry(ts=1750446004037,
metadata={}, values={DatapointKey(key=predict, report_strategy=None): 5.0})],
attributes=Attributes(values={}), metadata={'receivedTs': 1750446220502}),
ConvertedData(deviceName=model, deviceType=default, telemetry=[TelemetryEntry(ts=1750446304037,
metadata={}, values={DatapointKey(key=predict, report_strategy=None): 3.0})],
attributes=Attributes(values={}), metadata={'receivedTs': 1750446220506}), ...]

Is something wrong on my side ?

Or maybe there is no support for this feature ?

Hi @trya2l,

We discovered an issue with working with arrays in MQTT connector, it was fixed in 1a485e1 and will be available in the next release.
Also, please notice that you will need to have ${$.values.prediction} as value configuration for predict key.

Ok, thanks
