Hello everyone,
I have connected the electricity meters in my home in a cascade. I read both meters every 10 seconds with one Tasmota read head each. Within my “configuration.yaml” I have built a sensor which shows me how much electricity the device consumes within the cascade with the help of a division between the two meters.
When I now read out the value, it looks great in the average value (dark blue line):

However, as you can see from the graph, the real values (light blue) fluctuate greatly. I would now like to build an automation that kicks in when the appliance requires more than 1KW on average. But how can I do this? Is there a way to use the “average value” in the automation instead of the real value?
You can use Statistics to get the average value of a sensor.
Or you can use ha-average custom component, which I personally find really useful.

Hi zentay42, Hi community team,
I tried both, but I can’t get it running - but I don’t know why. So what I did, inside of the “template” section of the configuration.yaml I’ve create the sensor with the value shown in my first post:
- sensor:
# Stromzähler Wärmpumpe Verbrauch
- name: "Wärmepumpe akt. Verbrauch Kalkuliert"
unique_id: "WaermepumpeAktVerbrauchCalc"
unit_of_measurement: 'kWh'
device_class: "energy"
state_class: "total_increasing"
state: >-
{{ (float(states('sensor.gesamt_verbrauch'))) - (float(states('sensor.hausverbrauch'))) + (float(states('sensor.haus_erzeugung'))) - (float(states('sensor.gesamt_erzeugung'))) | round(1) }}
Afterwards I’ve installed the ha-avargage over HACS and create a “average” and a “statistics” inside the sensor section:
- platform: average
name: 'Average Verbrauch'
entities:
- sensor.warmepumpe_akt_verbrauch
- platform: statistics
name: "Heatpump in last minute"
entity_id: sensor.warmepumpe_akt_verbrauch
state_characteristic: average_linear
sampling_size: 5
precision: 1
When I have a look now inside my identities I can finde the “average” but this showing the more or less the same value as my sensor. The “statistic” entry I can’t find anywhere inside if my identities section.
Does somebody could help me, what I did wrong?
