Fuel consumption - how?

[Gawelex]

Hi, is there a way to show the fuel consumption in HA? Currently i can see an entity fuel_stream which shows value in % but don't have a clue how to use it to get the value i'm looking for.

Fuel Consumption - How to Track It

Hi @Gawelex,

Great question! Here's everything you need to know about fuel consumption tracking.

Available Fuel-Related Sensors

Sensor	Entity ID	Unit	Description
Fuel Stream	sensor.econet300_fuel_stream	% (should be kg/h)	Current fuel flow rate
Fuel Level	sensor.econet300_fuel_level	%	Fuel level in hopper
Fuel Consumption	sensor.econet300_fuel_consum	%	Some controllers only
Fuel Consumption Calc	binary_sensor.econet300_fuel_consumption_calc	on/off	Calculator enabled status

Understanding fuel_stream

The fuel_stream sensor shows the current rate of fuel being consumed. According to the official ecoNET cloud system, this value should be in kg/h (kilograms per hour), though it's currently displayed as percentage in this integration.

Typical values during operation: 1-5 kg/h (depending on boiler power)

I think controller Support

Controller	fuel_stream	fuel_consum	Notes
ecoMAX850R2-X	✅	✅	Full support
ecoMAX860P2-N	✅	❌	Partial support
ecoMAX860P3-V	✅	❌	Partial support
SControl MK1	✅	❌	Partial support
ecoMAX810P-L	❌ (null)	❌	Not supported
ecoMAX360	❌	❌	Not supported

How to Calculate Total Fuel Consumption

Try do it by template

template:

• sensor:

  • name: "Estimated Fuel Consumption kg/h"
    unit_of_measurement: "kg/h"
    state: >
    {% set stream = states('sensor.econet300_fuel_stream') | float(0) %}
    {% set max_feed_rate = 10 %} {# Your feeder max capacity in kg/h #}
    {{ (stream / 100 * max_feed_rate) | round(2) }}

📣 Feedback Request

If this works for you, please let me know:

1. What controller model do you have?
2. What values does fuel_stream show during operation?
3. Does the template calculation give realistic results?
4. Can you add Diagnostics File

With your feedback, we could potentially add native fuel consumption calculation directly to the integration!

Hi @Gawelex,
I've added native fuel consumption tracking based on your feedback.
Pre-release v1.2.1a2 includes:
sensor.econet300_fuel_consumption_total - tracks total in kg
Reset & calibrate services
Also fixed: fuelStream is now correctly shown as kg/h (not %). So your 1.0-3.4 values are actually kg/h.
I can't test this myself - my ecoMAX810P-L doesn't have fuelStream data. Since your ecoMAX860P3-O does, could you try it?
Install: HACS → Redownload → select branch v1.2.1a → restart HA
Let me know if the sensor appears and if the values make sense compared to ecoNET cloud!

Hi @jontofront ,
the sensor (sensor.econet300_fuel_consumption_total) appeared.
Fuel stream is showing values in kg/h.
The values for total fuel consumption seems vs econet cloud seems to be wrong. For couple of days HA entity is showing 14,911 kg when econet cloud - 31,04.
I think there must be something wrong with the math.
Attached fuel stream data from HA and econet cloud maybe you'll find a clue there. One more thing- the weight of a pellet portion which feeder gives in 15 min is 2550g.

Can you try and test the new version https://github.com/jontofront/ecoNET-300-Home-Assistant-Integration/releases/tag/v1.2.1a3
You can download by HACS

Hi, when looking at the graph of the fuel consupmtion it gives me like a momentary usage, but i'm not getting like a sum of the consumption within selected period of time.

[jontofront]

@Gawelex about your last question (graph shows momentary usage, not a sum): a history graph of sensor.econet300_fuel_consumption_total shows the running total, and fuel_stream shows the current rate. To see how many kg were burned per day, use a Statistics graph card with the Change statistic:

type: statistics-graph
title: Fuel consumption per day
entities:
  - sensor.econet300_fuel_consumption_total
stat_types:
  - change
period: day
chart_type: bar
days_to_show: 30

Use period: week or month for longer periods. A Utility meter helper on the same sensor also works if you want a separate daily or monthly counter entity. Both are now described in docs/FUEL_CONSUMPTION.md (part of v1.3.6-beta.3).

If you still use it: how does the total compare with the ecoNET cloud now? If it differs, the econet300.calibrate_fuel_meter action can set it to the cloud value, and a few days of both numbers would help me check the calculation.
