Hi,
I have a template sensor:
# ---------------------------------------------------
- name: "Elektriciteit subtotaal 2 power"
unique_id: "sensor.elektriciteit_subtotaal_2_power"
icon: mdi:flash
unit_of_measurement: "W"
state_class: measurement
state: >
{{ states('sensor.elektriciteit_kring_a_power') | float(default=0.0) +
states('sensor.elektriciteit_kring_b_power') | float(default=0.0) +
states('sensor.elektriciteit_kring_c_power') | float(default=0.0) +
states('sensor.elektriciteit_kring_d_power') | float(default=0.0) +
states('sensor.elektriciteit_kring_e_power') | float(default=0.0)
}}
and another “integration sensor” that calculates the riemann sum of this sensor
# ---------------------------------------------------
- name: "Elektriciteit subtotaal 2 energy"
unique_id: "sensor.elektriciteit_subtotaal_2_energy"
platform: integration
source: sensor.elektriciteit_subtotaal_2_power
unit_time: h
However, I noticed that if my sensor.elektriciteit_subtotaal_2_power has a static
value of “0.0”, the integration-sensor sensor.elektriciteit_subtotaal_2_energy gets the state of “unavailable”…
also, the graph is not updated anymore (1):
Question:
- why becomes the integration sensor “unavailable”? when there the parent sensor has a constant value of “0.0” ?
- why does the graph not update anymore. I would expect a horizontal line as there is no power consumption thus the subtotal of energy consumption should remain constant
kind regards,
Bart
PS
For some very specific reason, I had to redefine the source sensors as follows.
In fact, this is what I mean with a sensor with a permanent value of “0.0”
# ---------------------------------------------------

{{ "0" | float(default=0.0) }}
