Smart Life (tuya) show wrong temperature

jeroenm77 · March 17, 2022, 9:05am

I’m using the Tuya v2 to control two thermostats (brandname “Warmme”). They work and I can control the temperatures from HA. However the current_temperature is only updated after restarting HA or reloading the integration from the configuration->integrations screen. Would it be possible to script an automatic reload every few minutes? That would iron out the last wrinkle for me.

I have managed to get it working with a similar setup, thanks!

Am I retarded or WAHT?
HOW DID YOU GOT TO THIS MENU???

Having this on docker, Tuya Integrated, but wrong current temp

Verze	core-2022.4.5
Typ instalace	Home Assistant Container
Vývoj	false
Supervisor	false
Docker	true

BUT I CAN NOT FIND THIS CONFIG…
Have czech translation. so only see an “System Options” on tuya and there is only something about actualizing device (T/F slider)

Thanks for help, Jan

slmq · April 19, 2022, 8:26pm

What version doyou have, what type of instalation…i have grown grey on this…i don’t have it there

slmq · April 19, 2022, 8:33pm

I’m sorry, don’t have “Configure” on Tuya, only advanced options, which goes to “Enable actualiztion for newly added…”, but no config…could you be so kind and make screenshot, where are you clocking on “Configure”?
…sorry I’m probably braindead, but can’t see it

In case if anyone have to divide the temp, this is what I did. In my case temp was 5 times higher than it should be and max temp was 10 times higher.

Home Assistant 2022.4.6

For Docker:
vi /usr/src/homeassistant/homeassistant/components/tuya/climate.py

1. Setting MAX temp to 35

From:

        if self._set_temperature:
            self._attr_supported_features |= SUPPORT_TARGET_TEMPERATURE
            self._attr_max_temp = self._set_temperature.max_scaled
            self._attr_min_temp = self._set_temperature.min_scaled
            self._attr_target_temperature_step = self._set_temperature.step_scaled

To:

        if self._set_temperature:
            self._attr_supported_features |= SUPPORT_TARGET_TEMPERATURE
            self._attr_max_temp = self._set_temperature.max_scaled / 10
            self._attr_min_temp = self._set_temperature.min_scaled
            self._attr_target_temperature_step = self._set_temperature.step_scaled

You can change the min too, if it’s not set to 5.

2. Setting step value (for setting the correct temp)

From:

                   "code": self._set_temperature.dpcode,
                    "value": round(
                        self._set_temperature.scale_value_back(kwargs["temperature"])
                    ),

To:

                   "code": self._set_temperature.dpcode,
                    "value": round(
                        self._set_temperature.scale_value_back(kwargs["temperature"]) * 5
                    ),

3. To show correct current temp

From:

        if self._current_temperature.scale == 0 and self._current_temperature.step != 1:
            # The current temperature can have a scale of 0 or 1 and is used for
            # rounding, Home Assistant doesn't need to round but we will always
            # need to divide the value by 10^1 in case of 0 as scale.
            # https://developer.tuya.com/en/docs/iot/shift-temperature-scale-follow-the-setting-of-app-account-center?id=Ka9
            temperature = temperature / 10

        return self._current_temperature.scale_value(temperature)

To:

        if self._current_temperature.scale == 0 and self._current_temperature.step != 1:
            # The current temperature can have a scale of 0 or 1 and is used for
            # rounding, Home Assistant doesn't need to round but we will always
            # need to divide the value by 10^1 in case of 0 as scale.
            # https://developer.tuya.com/en/docs/iot/shift-temperature-scale-follow-the-setting-of-app-account-center?id=Ka9
            temperature = temperature / 10

        temperature = temperature / 5

        return self._current_temperature.scale_value(temperature)

4. To show current set temp:

From:

        temperature = self.device.status.get(self._set_temperature.dpcode)
        if temperature is None:
            return None

        return self._set_temperature.scale_value(temperature)

To:

        temperature = self.device.status.get(self._set_temperature.dpcode)
        if temperature is None:
            return None

        temperature = temperature / 5

        return self._set_temperature.scale_value(temperature)

Hello Yozen,
thanks a million, got it working, thanks to you.
I had my modified climate.py in …/custom_components and was on version 2022.4.5. After copying script to /components with old version of HA, nothing happened, but after updating HA to current, everything works flawlessly.
Thanks again
SLMQ

slmq · May 30, 2022, 9:48am

Hello Yozen,
just addendum - I have tried to edit climate.py on upgraded version of HA again and nothing changed, so I will wait till next update to recreate container with new settings in config.
Did you have to delete an install HA againt after edit? Restart seems to be not sufficient.

Regards
Jan

Found an open Issue on the Tuya integration and I’ve posted my issue there:

However just to repeat here because this is one of the top results when googling. This is utterly ridiculous and maddening.

If I run an API call against my AirCon unit I get the exact correct information:

{“result”:[{“code”:“switch”,“value”:false},{“code”:“temp_set”,“value”:24},{“code”:“temp_current”,“value”:26},{“code”:“humidity_set”,“value”:90},{“code”:“mode”,“value”:“cold”},{“code”:“windspeed”,“value”:“3”},{“code”:“c_f”,“value”:“C”},{“code”:“temp_set_f”,“value”:62},{“code”:“temp_current_f”,“value”:32},{“code”:“humidity_curre
nt”,“value”:55}],“success”:true}

And yet, what gets reported in Home Assistant via (and I will state because people here are using a variety) the OFFICIAL TUYA INTEGRATION:

hvac_modes:

‘off’

heat_cool

cool

heat

dry

fan_only
min_temp: -8.9
max_temp: -0.6
target_temp_step: 1
min_humidity: 0
max_humidity: 100
fan_modes:

‘1’

‘2’

‘3’
current_temperature: 0
temperature: -4.4
humidity: 90
fan_mode: null
friendly_name: Cabin Air Conditioner
supported_features: 13

Brilliant.

I’ve tried all various attempts of my least favourite subject, Math, to figure it out via custom integration to no avail. I get it close, but that’s with static figures, no idea if it relates once they move.

If anyone can see wood for the trees in the above figures and have a suggestion on the math, I’ll forever be in your debt. Until then, I guess I and we are at the mercy of Tuya and HA sorting this out.

hello,

i have the same problem, but i cannot find this file, climate.py to edit…

Home Assistant 2022.7.7
Supervisor 2022.07.0
Operating System 8.4
Frontend 20220707.1 - latest

slemens · August 11, 2022, 9:24am

Are there any Updates on this issue?
I have 6 BecaSmart BHT-6000 thermostats they are detected as thermostat (IAYz2WK1th0cMLmL), and they all show a wrong temperature. The real room temperature is 27.5°C, the displayed temperature is 5.5°C, so it’s divided by 5.

I’m using the official tuya integration on a raspberry pi:
Home Assistant 2022.8.3
Supervisor 2022.08.3
Operating System 8.4
Frontend 20220802.0 - latest

To fix the temperature issue with Tuya BHT-002 thermostats i recommend you to use my custom component based on the official Tuya integration found here

anverx · September 5, 2022, 8:45am

Thanks for clearly explaining the cause of the problem and providing a fix. I can sort of understand the developers of tuya integration refusing in include hacks to fix minstakes of individual HW manufacturers, but that doesn’t make our life any easier.

Could you publish a patch or even the whole climate.py file that can be droppped on top of exiting one? That would simplify the fix process. Even MACs filtering can be omitted as i only use a single type of the thermostat.

Thanks again for your efforts!

rnlascano · September 6, 2022, 10:20pm

There might be something i´m doing wrong, the error persists

rnlascano · September 8, 2022, 2:41am

Thanks! Working perfectly!!!

midstar · September 8, 2022, 9:07pm

Check the code changes i made to climate.py and base.py here Comparing home-assistant:dev...midstar:tuya_BHT-002_thermostat_workaround · home-assistant/core · GitHub

This turned out to be the easiest, (with the downside of having to repeat the process after upgrade). Much thanks!

sarunasr · October 29, 2022, 2:58pm

Hi @midstar
I trying this fix but I don’t understand why my tuya app still from cloud?

I uploaded modified tuya directory to the HA server:

Rebooted server
Added tuya integration through GUI.
