I use apex chart to display history of my download usage per day.

and here my config

type: custom:apexcharts-card
graph_span: 7d
span:
end: day
header:
title: Data Transferred
show: true
all_series_config:
stroke_width: 2
type: column
update_interval: 1m
series:

  • entity: sensor.fw_rx_bytes
    name: Download
    color: green
    group_by:
    func: max
    duration: 1d
  • entity: sensor.fw_tx_bytes
    name: Upload
    color: blue
    group_by:
    func: max
    duration: 1d

Looks like your sensors are not resetting exactly at midnight but a bit after. Share the history graph for sensor.fw_rx_bytes zoomed in to around midnight.

Try changing that to func: last
