Hello,
I am trying quite a long time to create sensors for saving only valid values especially for energy entities. I have several energy / consumption entities (PV production, production from battery (LG Resu 16), battery charging, water from espcam / AI on the Edge, gas from esp32 reed and grid via tibber websocket…)
My problem: When devices are unavailable / unknown / way wrong values from ai on the edge watermeter etc. these “errors” cascade for even more invalide states (e.g. my calculated self consumption etc.)
So I want to create always available and valid sensors as a base for the energy dashboard and own calculations. And of course cycling utility meters.
I have tried several ways:
template-sensor like this:
- name: "Gas Valid"
unique_id: "gas_valid"
state: >
{%- set current_value = states('sensor.gaszaehler_gaszaehler') | float -%}
{%- set last_valid_value = states('sensor.gas_valid') | float -%}
{%- if is_number(current_value) -%}
{%- set new_value = max(current_value, last_valid_value) -%}
{{ new_value if new_value <= last_valid_value + 0.05 else last_valid_value }}
{%- else -%}
{{ last_valid_value if is_state('sensor.gas_valid', 'unknown') else 0.0 }}
{%- endif -%}
unit_of_measurement: "m³"
device_class: gas
state_class: total_increasing
icon: mdi:gas-cylinder
the problem with this approach: after reloading the yamls to get this active the “valid” sensor is unavailable as there is no former valid value. If I set a valid value manually it works until I reload my yamls to add further configuration / sensors (or just restart for updating HAOS…)
My “working” approach:
automation to set only valid states to input_number sensors like this:
platform: time_pattern
seconds: "30"
condition: template
value_template: >-
{{ float(states('sensor.pv_produktion_shelly')) >
float(states('input_number.produktion_aus_pv_nur_gueltige')) }}
service: input_number.set_value
data:
value: "{{ float(states('sensor.pv_produktion_shelly')) }}"
target:
entity_id: input_number.produktion_aus_pv_nur_gueltige
to get these values available for utility meters I have created template sensors getting the state of the input_numbers.
So this a very unconvenient way in my opinion.
Do you have any suggestions how to it better / more convenient / more efficient?
Thank you so much!
Andi
