Offset between Graph and datas

[Pierrick]

Hi Guys,

Can someone explain why for few graphs (not all), I have an offset between the datas stored and the graph…
For exemple, the graph shows a value of 95L at 08:13:36 and 123L at 09:48:12

But the exported datas are:

sensor.eau_froide_mois,94.75,2024-09-07T06:13:36.705Z
...
sensor.eau_froide_mois,123.25,2024-09-07T07:48:12.659Z

To sum up Graph vs datas:
95 <==> 94.75
123 <==> 123.25

I tried to display another entity on same graph, and the new entity is displaying correctly with some .25 or .75 values…

See that “Z” at the end of the timestamp?

That means it is UTC time. You will need to add your time zone offset. Which is two hours by the looks of it.

Hi @tom_l
My probelm of offset is not on the date but the value!

The graph is rounding to the nearest integer. What do you have the display precision set to for that sensor?

Click on the entity then click on the cog icon in the top right of the pop-up card

Thank you @tom_l , that’s exactly for this reason!!!
