MQTT sees only first value

[clertes]

Hi,

I'm using daly-bms-cli to send Daly BMS data to my mosquitto MQTT server which is then parsed via telegraf into influxdb.

I can see that daly-bms-cli is publishing the data when I start it with --verbose:

Unfortunately I can only see the first value when I'm using chronograf/grafana, in this case it's dalybms/soc/total_voltage.

I've also tried to listen to the MQTT messages via "MQTT Explorer" where I can also confirm that it seems like only the first value is being sent.

My telegraf.conf is configured like this:

[[inputs.mqtt_consumer]] servers = ["tcp://127.0.0.1:1883"] username = "XXXXXXX" password = "YYYYYYYYYYY" topics = [ "dalybms/#", ]

data_format = "value" data_type = "float"

As I'm running out of ideas, do I miss something?

Did you fixed this ?

[clertes]

Nope, went with another solution.

Can you share ? I am also trying to draw my data from Daly BMS to some kind of web interface ...
