ESPHome total_daily_energy sensor rainfall

[devjklein]

I am still trying to use total_daily_energy sensor to get the total rainfall in a day, and have this amount reset at midnight. However, it does not report as expected. While my pulse_meter total value shows the total number of pulses recorded (calibrated to inches of rain), the total_daily_energy sensor shows a slightly different value. Is this due to the Riemann sum method that the sensor uses? Why does it not simply sum together all the values it receives?

I am thinking about sticking with the pulse_meter total value and resetting that each day at midnight.

Edit: What are the differences between the left, right, and trapezoidal methods? I do not understand this.

What are the differences between the left, right, and trapezoidal methods?

See this post:

Calculating Watts / Kw and KWh

Make a template sensor for the W. You already have the equation and it’s written here enough. - platform: template sensors: power_watts: friendly_name: "Power Watts" unit_of_measurement: 'W' value_template: > {% set PF = state_attr(input_number.power_factor.state | int ) %} {% set V = state_attr('sensor.pow_voltage', 'V') %} {% set A = state_attr('sensor.measured_current', 'A') %} {{ PP * A * V }} Now, to properly cal…

As water is not energy, you probably want this sensor instead:

Thank you for this information. I have moved away from the total_daily_energy sensor, and I am now just using one pulse_meter sensor for my rain gauge, with a total: which resets at midnight via:

on_...:
  then:
    - pulse_meter.set_total_pulses:
        id: pulse_meter_id
        value: 0

This way, I get rain per minute as well as total daily rainfall in just a few lines of code and one sensor.
