Negative and wrong values for energy monitoring (smart plugs)

Energy
1

hello all
Sometimes i have negative values coming from my smart plugs (aqara, or shelly plug s2) + they values are even very wrong - see picture below, i am really not using 0,8MWH in one day :slight_smile:
I can not really figure out what is the problem. I already checked the forum, but seems people only have negative values ,not also wrong as i have.
If i check the device it self (pic 2), everything seems to be normal.
Anyone any suggestions?
Thanks

I got tired of this problem myself, it seems to happen with great regularity on a lot of Chinese plugs. This is when I decided to use PowerCalc for everything so I had some control. Now I got rid of 90% of my old crappy plugs that do this (and then blow up my Energy dashboard) but now I use PowerCalc and just have something like this for every entity:

- entity_id: switch.space_heater_switch
  fixed:
    power: >-
      {% set power = float(states('sensor.space_heater_active_power'), 0) %}
      {{ power if power > 0.01 else 0 }}

This prevents the negative spikes and is using all the native stuff on the plug. Yes, it’s a lot of work to set up every device for PowerCalc but I also get a comprehensive report of every room or group I want, and that was worth the hassle of PowerCalc in the first place.

thank you for answer, will give it a try. even thought i hoped there is some easier solution . at the end the data on the device it self are correct, they are just presented wrongly in energy dashboard.
BTW - what smartplug with energy metering would you recommend ? I have aqara smart plug and Shelly plug s2 and both are showing wrong values in energy dashboard.
Thank you
