DDS5188 kWh meter

Energy
1

I’m new to HA, and I’m currently migrating my Domoticz install to HA.
Most of the things are already migrated, chatgpt is a great help :slight_smile:

One of the things I cannot figure out due to the learning curve is to get my DDS5188 power meters into HA.

They are connected on a ESP8266 board, which I already migrated to ESPHome, but I don’t get any readings in HA.
I’m pretty sure this is because the config is wrong, but I don’t have any clue how to make a correct config.

The DDS delivers 0,5Wh/imp. So 1kWh is 2000pulses.
This is what I currently have in my esp config file:

#Boiler 
sensor:
  - platform: pulse_counter
    pin: GPIO12 #♦D6
    name: " Boiler Energy Pulse Counter"
    id: energy_pulse_counter  # Define the ID here
    unit_of_measurement: 'pulses/min'
    icon: mdi:pulse
    update_interval: 60s
    filters:
      - multiply: 0.03  # 0.5 Wh per pulse, converted to kWh over the update interval

  - platform: total_daily_energy
    name: "Boiler Total Daily Energy"
    power_id: energy_power
    unit_of_measurement: kWh
    accuracy_decimals: 3
    filters:
      - multiply: 0.0005  # 0.5 Wh per pulse, converted to kWh

  - platform: template
    name: "Boiler Current Energy Usage"
    id: energy_power
    unit_of_measurement: W
    lambda: |-
      return id(energy_pulse_counter).state * 30.0;
      
time:
  - platform: homeassistant
    id: homeassistant_time

It would be nice to have a realtime usage in Watt and a total usage per day in kWh.

Can someone give me a bump into the right direction ?

I’ve tried numerous combinations which I obtained though ChatGPT, but nothing seems to do what I want. Also worth mentioning is that I had the same ESP board working with my Domotics install:
Debounce time 200
counter type Delta/total
internal pullup enabled.

In the meanwhile I have it sort of working with the code below. Remainig are the multipliers.
How do I convert 0.5wh/imp from my meter to this config ?

sensor:
  - platform: pulse_meter
    pin:
      number: GPIO12
      mode: INPUT_PULLUP
    name: Boiler huidig verbruik
    unit_of_measurement: "W"
    accuracy_decimals: 0
    internal_filter: 150ms
    timeout: 5 min
    filters:
      - throttle: 150ms
      - multiply: 0.3
    total:
      name: Boiler verbruik totaal
      unit_of_measurement: "kWh"
      accuracy_decimals: 0
      filters:
        - multiply: 0.0005
