Manual utility meter with custom timestamps

Hi,

I would like to manually enter water and electricity meter readings with the ability to set a custom timestamp, so I can take photos of the meters and enter them a few hours later into the HA.
I just want to have data graphs from water and electricity meters.

With input_number I can’t enter the time at which the photo of the meter was taken and I can’t edit the graph when I make a mistake.

Is there any integration for this?
