huge peak due to meter replacement

Hey all,

in preparation of installing a charger for my EV, my meter was replaced from a single phase to a 3 phase. Now I see a huge spike in my energy consumption (guessing because the new meter starts at 0 again?). Any way to fix this?

Just delete the Friday data.
First backup your db.
Mouse on Friday consumption, hold shift and click and domoticz will ask you to delete.
Then wait and see what will happen.

Tnx for the help, was not aware of this feature! This only works for the top graph, correct? The peak is only in the accumulated usage graph, not the 5 minutes line. Do I need to delete just 1 value out of the top line? or should it be the one that is the first at restart of Domoticz after installation of the new meter?

The daily usage value is calculated as the difference between the minimum and maximum value of the previous day, that is why you get these large values. It will only affect the value of that one day (in the multimeter_calendar table). Next days will be correct again.

I think with version 2024.1 the "hold shift click" method also works on the daily value graph.

You could replace the current values with the correct values, instead of deleting them, but then you have to go directly into the dbase. The values of that day will probably be low anyway, depending on how long it took to replace your meter etc.

I experienced the same but Deleting the peak value didnt work for me. It just moved the peak to the next day because now that one has the big difference between last values of both days. Did it work for you?
