Utility meter wrong monthly/yearly values for gas only

Configuration
1

I have a p1meter installed in my environment based on an esp8266 (https://github.com/Diechel/esp8266_p1meter) and it works like a charm.
I have created the following gas content for file yaml file: utility_meter.yaml
Note: I removed the power configuration as I don’t have issues with those.

hourly_gas:
  source: sensor.P1_Gas_Usage
  cycle: hourly
daily_gas:
  source: sensor.P1_Gas_Usage
  cycle: daily
weekly_gas:
  source: sensor.P1_Gas_Usage
  cycle: weekly
monthly_gas:
  source: sensor.P1_Gas_Usage
  cycle: monthly
yearly_gas:
  source: sensor.P1_Gas_Usage
  cycle: yearly

This is my sensor (sensors.yaml) that is being used for it.

- platform: mqtt
  name: P1 Gas Usage
  unit_of_measurement: 'm3'
  state_topic: "sensors/power/p1meter/gas_meter_m3"
  value_template: "{{ value|float / 1000 }}"

And template sensors:

- platform: template
  sensors:

With above configuration I’m getting absurd values for month and year (and corresponding price calculations)

I’m searching for weeks now were i made a mistake and why the readings are wrong but can’t find it.
I hope someone else on this forum can help me with this?

Is it increasing values each time home assistant is restarted?

Seems you need availability template to avoid 0 state at startup.

Hi, thanks for thinking with me and my apologies for my late reply. Did some testing but values didn’t increase after reboot. Tomorrow morning I will check that availability template you referring to, thanks :+1:
