Question on Intergration Sensor

ESPHome
1

I have just calibrated my rain bucket to the result of a pulse counter sensor. I want to add integration sensor but the output doesnt match the pulse counter sensor.

[23:49:12][D][pulse_counter:159]: 'Rain Bucket': Retrieved counter: 4.00 pulses/min
[23:49:12][D][sensor:092]: 'Rain Bucket': Sending state 1.02564 mm/min with 2 decimals of accuracy
[23:49:12][D][sensor:092]: 'Total Daily Rain': Sending state 0.27766 mm with 4 decimals of accuracy
[23:49:12][D][pulse_counter:164]: 'Rain Bucket': Total : 4 pulses
[23:50:12][D][pulse_counter:159]: 'Rain Bucket': Retrieved counter: 0.00 pulses/min
[23:50:12][D][sensor:092]: 'Rain Bucket': Sending state 0.00000 mm/min with 2 decimals of accuracy
[23:50:12][D][sensor:092]: 'Total Daily Rain': Sending state 0.81869 mm with 4 decimals of accuracy
[23:50:12][D][pulse_counter:164]: 'Rain Bucket': Total : 4 pulses
[23:50:12][D][sensor:092]: 'Energy Meter House': Sending state 4.00000 kWh with 0 decimals of accuracy


  - platform: pulse_counter

    unit_of_measurement: 'mm/min' # pulse / min

Why are you measuring rain in kWh?

:thinking:

I forgot to change it. I was just using “total” to check total pulses. I want to remove that when I get the correct value from integration.

Looks like the pulse counter total reporting does not include the filter.

Setting the integration_method to left may give you less error for this sort of input.

Thanks tom. Left worked while right didnt. I have been browsing over this parameter many times but never thought this could be the culprit.

Btw, what is the difference between trapezoid, left and right? The wiki didnt explain each option.
