MQTT data gets corrupted sometimes in home assistant

[robert72 (Robert v Ommen)]

Hi there,

I have a modbus kWh meter for a solar panel. A Raspberry Pi python script pulls it’s data and sends it to the online mqtt broker HiveMQ.
That broker is in bridge mode with my home assistant mqtt broker. That all is working very fine, but sometimes a strange high value is visible in the energy dashboard of home assistant.
At first I thought this high value was measured by the raspberry pi, but when I start logging both mqtt brokers, it became visible, no problems there.
When the data is sent through without any trouble, how is it possible it gets corrupt in home assistant?
At this picture the hickup is visible:

This are the MQTT brokers: (don’t mind the high value, that was at another timepoint)

And here visible in statistics:

I hope someone can point me in the right direction, Thanks in advance.

Bad Data in Energy Dashboard

Something happened yesterday afternoon that has caused a problem with my energy dashboard. It seems that the sensor.grid_export_energy was at 13,790.76 kWh at 3:50 pm then it rolled over to zero at about 4:15 pm. I’m getting data via the Enphase Envoy integration, but it’s unclear to me how it gets into the grid_export_energy entity. It isn’t listed in the Envoy entities, but I did fine a sensor.grid_export_power in my config file that I must have put in on the advice of a tutorial at some po…

Hi Jorggs, thanks. I was looking deeper in my own question and the noticed, the corrupt data at timepoint 8:25, equals the data in the broker log at timepoint 7:54

Somehow the error is in the bridge it seems
