I had to change a temp device. I followed the instructions to keep all history values but I ended with only history of this year. Should it be a bug or is there another way to keep history of many years?

Could be an issue in your database table with the old values.
You can check with SQLite DB browser on a backup before the replacement what could be the issue.

What might be an issue Walter? Where/ what to check?

I dont know, some inconsistency somewhere.

Walter, do you know where to find thd routine in the source? To me ik looks like an SQL error but I don't have the skills to figure out where tk look kn the sourcecode

It is not a normal error as it does normally do all history data. So something probably is wrong in your data that gives an hickup.

I also have no idea where the replacement function including SQL query is. But better look at your database first.
