update historic data via api

[JanJaap]

I had a problem with the plugin for one of my solarpanels. I have the data from the app and now want to load that via the json api as per instructions here:
https://wiki.domoticz.com/Domoticz_API/ ... ed_counter

So I compile the following URL:
http://<my ip>:8080/json.htm?type=command&param=udevice&idx=490&nvalue=0&svalue=5349003;26900;2025-05-22

Response in the browser:

However no data added for May 22:

What am I doing wrong? Tried for different date's, same result

Is there already data for the 25th? Because then you will get 2 database entries for the same date in the meter_calendar table and that cause trouble. It will not over write the data it will add an entry and probably just use the first one it will find (the old one)
