MQTT Tasmota Sensor wrong numbers / peaks

Hi,

for some reason i have wrong numbers in my Home Assistant.
I tried 3 different sensors, everyone has the same problem with wrong data/peaks in it.

It is a Tasmota MQTT Sensor and for some reason i got crazy peaks in it.
It cannot be the device cause i tried 3 different devices now.

It must be something in the transmission or as I now tend to think, a problem in Home Assistant.
I just use the normal Tasmota integration, nothing more…

Does anyone has an idea?
Thats the Peaks. It reads my smart meter and the line can never drop like that…
