It would be wonderful to be able to do a simple .csvc export from history. The History function has come a long way, and is terrific. I can easily select an entity and a date range, and it produces a nice graph. But there are times when I want to export that data to do further analysis. I know there are tools that can operate on my database, but it would be so much nicer to have an “Export to .csv” button added to the history graph!
Now that is a very interesting idea. That would have helped a lot back when I was debugging my outdoor PIRs and radars. So basically two columns, timestamp and states, maybe additional columns for the attributes, if any. Maybe the ability to combine multiple sensors in additional columns.
Hmm… Shouldn’t be too hard to implement 
Something like this ?
The CSV file:
Time stamp,State
sensor.outside_temperature

Yup, exactly. There is a Notify function that allows me to log any entity to a CSV file, but that is not nearly as useful and friendly as having an Export CSV option in the history tab.
This looks like a duplicate of
