Total Daily Energy Sensor¶
The total_daily_energy
sensor is a helper sensor that can use the power value of
other sensors like the HLW8012, CSE7766, ATM90E32, etc and integrate
it over time.
So this component allows you to convert readings in W
or kW
to readings of the total
daily energy usage in Wh
or kWh
.
# Example configuration entry
sensor:
- platform: total_daily_energy
name: 'Total Daily Energy'
power_id: my_power
unit_of_measurement: 'kWh'
state_class: total_increasing
device_class: energy
accuracy_decimals: 3
filters:
# Multiplication factor from W to kW is 0.001
- multiply: 0.001
# The power sensor to convert, can be any power sensor
- platform: hlw8012
# ...
power:
id: my_power
# Enable time component to reset energy at midnight
time:
- platform: homeassistant
id: homeassistant_time
Configuration variables:¶
power_id (Required, ID): The ID of the power sensor to integrate over time.
restore (Optional, boolean): Whether to store the intermediate result on the device so that the value can be restored upon power cycle or reboot. Defaults to
true
.method (Optional, string): The method to use for calculating the total daily energy. One of
trapezoid
,left
orright
. Defaults toright
.All other options from Sensor.
Converting from W to kW¶
Some sensors such as the HLW8012 expose their power sensor with a unit of measurement of
W
. To have your readings in kW
, use a filter:
sensor:
# The power sensor to convert, can be any power sensor
- platform: hlw8012
# ...
power:
id: my_power
filters:
# Multiplication factor from W to kW is 0.001
- multiply: 0.001
unit_of_measurement: kW
Lifetime instead of Daily¶
For a more-generic version of this component which does not reset every midnight, see Integration Sensor, which can provide device-lifetime values instead of daily values with the following example settings:
# Example configuration entry
sensor:
- platform: integration
name: 'Total Energy'
sensor: my_power
time_unit: h
restore: true
state_class: total_increasing
device_class: energy
