only save value historical on change and not on interval

[killerbeat12]

is it possible to save a value only on change in the database? if i "enable registration" it will also save a value every "x" sec
i only would like to save the value that is received on change, so no samples saved every "x"sec

That is what thr "Saved if change" does in the Tag options.

i Henjoe, yes i now.. but i ONLY want to save it on change, but if i disable "Registration enabled" then it will not save on change. if i enable "Registration Enabled"it will save on change BUT also on interval, and i ONLY want save on change?

That could be Bug. If interval set to 1secs and Save if changed is checked, when the value does not changed, it should not saved.

Hi, I imagine that you save data to see it on a chart. if your value does not change for days, your chart is empty (because you need two points to draw a line). it is therefore a good practice to put a minimum interval so that you have values. but if it bothers you, set the interval to 99999!

Never knew this is how it works. I thought the interval is for interval to check wether the value changes or not 😅
