353:  if native_unit_of_measurement in (TEMP_CELSIUS, TEMP_FAHRENHEIT):
              if self.hass is not None: **<- add this line for fast fix**
                  return self.hass.config.units.temperature_unit
          return native_unit_of_measurement

and then works:

[sagioto]

I applied the fix as a custom component, tried to both reload the plugin and delete and add it again, It didn't work for me, I still see the sensors as unsupported Is this scheduled to be in the next release?

[pserranoa]

this workarround works for me

[magno-santos]

I'm having difficulties applying this fix since I don't have that folder. Should I create it?

[sagioto]

@drager I’m running in docker and don’t have that folder as well that’s why I used custom_compoent The component is recognized when loading ha but the fix doesn’t work Shouldn’t I see a null pointer exception in the logs without the fix?

Yesterday, Home Assistant 2022.2 was released. Could you try upgrading to that version and see if the issue has been resolved?

If not, Home Assistant 2022.2 contains a new diagnostic tool. There is now a "Download Diagnostics" button on each Tuya device on the device page. Clicking that button will download diagnostics information for that specific device. Drag the downloaded file into this issue. It will help with finding out what the problem is.

[magno-santos]

Here you have the Diagnostics.

@magno-santos Looking at your data dump:

    "function": {},
    "status_range": {},
    "status": {},

☝️ Those are the functions and statuses the Tuya API provides to work with. As you can see, it provides nothing, thus Home Assistant won't be able to do anything either.

In you cause, I would recommend to submit an ticket with Tuya, asking if they can do anything about it (log in to your Tuya IoT account to do that).

Sorry! wish I had better news to share with you.

So, playing with the api, the device itself doesn't provide the functions, but when querying the category it does. Is there some way to get ha to revert to querying the category if the device returns empty? GET "https://openapi.tuyaus.com/v1.0/iot-03/categories/wsdcg/functions"

@sagioto That has no use, as that isn't standardized, additional that only provides functional information, which without a state, is useless anyways 🤷

In these cases, there is only 1 thing that can be done: Contact Tuya about your device and hope they can adjust it (which they cannot in all cases, which is often to blame to the manufacturer).

[marcusforsberg]

I have the same model as @magno-santos (a Nedis sensor and a gateway) and this was Tuya's response:

I checked the functions of this product. They are all customized by the device manufacturer and do not conform to the standard instruction set of Tuya Cloud. Therefore, cloud API is not supported to control the device and obtain the status. Use the product on the APP (the device only supports the APP).

Looks like we're out of luck! 😅

[frenck]

Last possible source/route might be contacting the manufacturer, however, I haven't seen anybody having success with doing that :(

[sagioto]

I just moved to use ZHA with the sonoff usb zigbee dongle, the sensors work fine that way

[frenck]

Alright, as you are the reporter of this issue, I'll go ahead and close it.
