Phone battery level because has sum = 0

[sandros06]

Hello I have detected a little problem for phone battery level

• WARNING - Invalid row skipped: ('sensor.phone_battery_level', '%', None, 0, None, 51.0304190749175, 1742410800.0)

Interpretation:

statistic_id: 'sensor.phone_battery_level' ✅ not None
unit: '%'
has_mean: None ❌
has_sum: 0 ❌
state: None
mean: 80.0
start_ts: 1742511600.0

value = None
if has_sum == 1 and state is not None:
    value = state
elif mean is not None:
    value = mean

potential fix
