Hi @mboisson ,
As this driver is aimed to support mostly the Tuya models, it has the energy reports coefficients (dividers) hardcoded into it. So it is quite possible that the Third Reality dividers are not correct..
I can recommend trying Jonathan's driver : New: Third Reality Power monitoring plug - #60 by jonathanb . You can switch temporarily to the HE inbuilt 'Device' driver to clear all states and state variables, before you assign Jonathan's driver. It is written especially for the Third Reality outlets and tested by many other users.
If it reports the energy consumption correctly , please post the State Variables, I will use the information to correct this driver too.
