Tuya - WifiDualMeter Issue (missing entities)

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.:

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

  name: Home
  unit_system: metric
  # etc

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

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

      state_class: total_increasing
      state_class: total_increasing
      state_class: total_increasing
      state_class: total_increasing
      state_class: total_increasing
      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?

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.
