Checklist

• I have enabled debug logging for my installation.

Describe the issue

Total consumption at the sensor in home assistant is higher than the consumption i get from the api.
When a charging starts, the consumption drops around 300kwh. This gives strange consumptions when calculating to minus charging consumption from Total consumption.
Please se attached sreendump.
Is this only happening for me?

Reproduction steps

1. Charge
2. Watch the sensor drop

How have you setup the Total consumption sensor?

[FS-DK]

Sorry for the late reply.
It's setup as an utility meter with a reset daily.
I have tried both with net consumption and without net consumption. The result was the same.
I have also tried uninstalling Monta, deleted the database, and then installed Monta again.
With the same result.

[nickknissen]

What does your Last meter reading history look like?

My Zaptec Go data looks like the following:

There seems to be a bug in the data from Monta where lastMeterReadingKwh is not always cumulative.

You could try enabling Periodically resetting in the utility meter to see if it fixes the issue.

[FS-DK]

My last meter reading looks like this with my EVBox Elvi.
It's different from yours, as mine is total increasing.
It has not always been making these drops. It started normal with no drops at all, but at the end of October it started making the drops. What is realy strange, is that it always drops to the same level. It drops to 1520,010 kWh.
My utility meter is resetting daily.

[nickknissen]

The last meter reading data comes directly monta api. You could try to create a template sensor which only increases in value

sensor:
  - platform: template
    sensors:
      tpl_monta_last_meter_reading:
        value_template: >-
          {% set current_value = states('sensor.last_meter_reading') | float %}
          {% set previous = states('sensor.tpl_monta_last_meter_reading') | float %}
          {{ [current_value, previous ] | max }}

[FS-DK]

I finally got it working with your suggestion. But I had to modify it a bit and use input counters.

But still..... it's a very strange behavior that just started out of nothing.

template:
- sensor:
- name: "Akkumuleret forøgelse"
state: >
{% set last = states('input_number.last_positive_value') | float(0) %}
{% set current = states('sensor.monta_xxxxxxxxxxxxx_last_meter_reading') | float(0) %}
{% set accumulated = states('sensor.akkumuleret_forøgelse') | float(0) %}
{% if current > last %}
{{ '%.3f' % (accumulated + (current - last)) }}
{% else %}
{{ '%.3f' % accumulated }}
{% endif %}
unit_of_measurement: "kWh"

input_number:
last_positive_value:
name: Sidste positive værdi
min: 0
max: 1000000
step: 1
akkumuleret_forbrug:
name: Akkumuleret forbrug
min: 0
max: 100000000
step: 0.01
unit_of_measurement: "kWh"
