Cannot get voltage/current from wifi smart meter

Tinwelint78 commented 2 years ago

The problem

I'm trying to get energy meter from a tuya wifi smart meter. I have succesfully added total energy in kWh, but I cannot select this sensor in the energy panel, so I was trying the "integral" method, as described in #536, but even if I see the current/voltage sensor values from Tuya IoT, I cannot see them from DP dump.

Environment

Localtuya version: default version from HACS
Last working localtuya version (if known and relevant): -
Home Assistant Core version: 2021.9.5
[x] Are you using the Home Assistant Tuya Cloud component ?
[x] Are you using the Tuya App in parallel ?

Steps to reproduce

Configuration `configuration.yaml` or `config_flow`

Current and voltage values are there, how can I get them? Alternatively, How can I make Energy panel accept total energy sensor?

Maybe this is being addressed by #473?

I have this working, for both LocalTuya and Xiaomi integration smart plugs. If it's still not working for you, let me know and I can share some config.

Tinwelint78 commented 2 years ago

I managed to use total energy by defining the sensor as "device_class:energy". I haven't been successfull in reading voltage/current meters though, so if you can share a config for doing this I'll be grateful!

jeremysherriff commented 2 years ago

I haven't been successfull in reading voltage/current meters though

It took me quite some time to work out what you mean by this, sorry. I didn't realise that the integration doesn't support your device fully!

I believe the values you are trying to get are not yet supported by this integration. The PR you linked (#473) or something similar is needed.

another way is in the sensor.py add following

from homeassistant.components.sensor import DEVICE_CLASSES, DOMAIN, STATE_CLASS_MEASUREMENT, SensorEntity

class LocaltuyaSensor(LocalTuyaEntity, SensorEntity):

**@property
def state_class(self):
    return STATE_CLASS_MEASUREMENT**
