DTS238-7 Energy Meter Configuration

[andyrisko]

I purchased the DTS238-7 energy meter and encountered issues with the official Tuya integration in Home Assistant, as it incorrectly handles the device. The Tuya Local integration has a similarly named file: dts238_7_energy_meter.yaml, but it recognizes the device as earu_smart_wifi_circuit_breaker_with_energy_monitor.yaml.

I managed to obtain some original documentation (attached) and modified the original configuration file so that the device is now recognized and displays correct values:

name: Energy meter
products:
  - id: i55reuttymjocx0j
    name: DTS238-7 Smart meter IVAP
entities:
  - entity: sensor
    name: Total energy
    class: energy

        type: integer
        name: sensor
        unit: kWh
        class: total_increasing
        mapping:
          - scale: 100
  - entity: sensor

    class: frequency

    dps:

        type: integer

        unit: Hz
  - entity: sensor
    name: Total Power Factor
    class: power_factor
    category: diagnostic
    dps:
      - id: 111
        type: integer
        name: sensor
        unit: "%"
        mapping:
          - scale: 1000

However, I got stuck with per-phase handling, like this:

- entity: sensor
  name: Active Power A
  class: power
  category: diagnostic
  dps:
    - id: 6
      type: base64
      name: sensor
      unit: kW
      mapping:
        - mask: "FFFFFFFF0000000000000000000000"
          scale: 1000

I need help with the following:

Should I modify the original configuration file, knowing that an update might overwrite my changes? The issue is that not even the IDs match – the original file uses 1rlikmowi2erb6qw, while mine uses i55reuttymjocx0j. Should I create a new file in a more protected location where the integration will still recognize it?
Should I try forking the repository? Maybe I will eventually figure it out.
I’m not an expert, but I would like to track reactive power on a graph. Any guidance would be much appreciated!
