Shelly 3EM

Hello,

my Shelly 3EM module was offline for few weeks. Energy consumption was not counted during that time. After that I calculated manually the value in kWh that was skipped. I wanted to add missing consumption in my Symcon. But it doesn’t work. If I increase marked variables manually they are overwritten with old values during next update of these variables.

I also couldn’t find corresponding data on Web server of Shelly 3EM. How can I correct manually those variables ?

What could be the solution ?
