Tuya - WifiDualMeter Issue (missing entities)

Configuration
21

Using LocalTuya I was able to successfully set up the wifi dualmeter… nevertheless, there’s no way to integrate it in “Energy” dashboard.
The sensor entities are set, but when I try to set up the Energy dashboard, they are not proposed.
This guide: Frequently Asked Questions about home energy management - Home Assistant
suggests going to Developer Tools > States to check the entities.
I can’t find anything wrong: i.e.:

sensor.107_reverse_energy_a
107-reverse energy A
2.32	raw_state: 2.32
unit_of_measurement: kWh
device_class: energy
friendly_name: 107-reverse energy A

Very same page suggests also that “state_class” must be total or total_increasing… but I don’t know how to check this, as it’s not reported in Developer Tools > States … any idea?

use customize in configuration.yaml


homeassistant:
  name: Home
  unit_system: metric
  # etc
....

  customize:
    # Add an entry for each entity that you want to overwrite.
    sensor.107_reverse_energy_a:
      state_class: total_increasing

Indeed had to add some code to configuration.yaml (as mentioned by @francisp

homeassistant:
  customize:
    sensor.wifi_dual_meter_forward_energy_a:
      state_class: total_increasing
    sensor.wifi_dual_meter_forward_energy_b:
      state_class: total_increasing
    sensor.wifi_dual_meter_reverse_energy_a:
      state_class: total_increasing
    sensor.wifi_dual_meter_reverse_energy_b:
      state_class: total_increasing
    sensor.wifi_dual_meter_total_forward_energy:
      state_class: total_increasing
    sensor.wifi_dual_meter_total_reverse_energy:
      state_class: total_increasing

Would I want to integrate the dual-meter in the standard “Energy usage” dashboard:

  • as “grid consumption” I set variable 108 (dp_energy_forward_b)
  • as “return to grid” I set variable 109 (dp_energy_reverse)

And this works fine, and I get the diagram of energy consumed or returned to the grid…
But for “solar production” what could I use?
The value should be the difference between dp_energy_forward_a (energy consumed by the load) - dp_energy_forward_b (grid consumption).
But how can I define such a variable?

26

can you share your complete config with the scaling factors, offsets, etc?

the dual ct monitor works only on protocol 3.5, try a different version of local tuya that supports it. the single ct monitor uses protocol 3.4.

Hi. Thank you very for this and to those who contributed to this topic. My dual meter was giving even giving no entity through tuya smart ! Now I can get all of them using this topic. The complete list of mapping is very usefull ! The 2 firsts 1 & 2 were referenced as 130 & 131 in my case.
Kind regards.

is it possible to define an entity that gives me the daily sum of another entity? I need to create a card that displays my daily consumption. Thanks

Thanks for the information, local tuya cannot find PJ-1103A “wifi_dual_meter” automatically.
going to add device, local tuya protocol version 3.5 is not available, cannot be selected. 3.3 or 3.4.
“Entity type selection” does not have “energy” option as platform. I had to choose “sensor”.
Even if the feature appears later, it remains “Unavailable”.
When I proceed with “edit device” in the configuration, even if I enter all the information, it does not proceed as if I have entered a field that I did not fill in.
I’ve been trying but I can’t seem to make any progress.
I would be glad if you can help. Thanks in advance!

This has been incredibly helpful. Thank you! Like for @GeoGitHubHA, the Total Forward/Reverse Energy endpoints were 130 and 131 for me. Separately, I configured some end points with scaling factors of 0.0002, .02, etc., to correctly scale 240V readings while the PJ-1103 monitor is powered by 120V (in the United States).

Please @bushwoelie could you share your config code? I cant/dont know how to change the values to see all the items like Hz, Amps, kWh, etc… Please!
