[Bug]: Tuya thermostat wrong configuration and temperature value

[Hammerhand17]

LocalTuya Version

2024.5.0

Home Assistant Version

2024.5.5

Environment

• [X] Does the device work using the Home Assistant Tuya Cloud component?
• [ ] Is this device connected to another local integration, including Home Assistant and any other tools?
• [X] The devices are within the same HA subnet, and they get discovered automatically when I add them

What happened?

I have a tuya thermostat for fancoils with the following info: Product Name 柏益加温控器（空调） Device ID 31571686cc50e3e73cd9 Product Category wk Device Status Online Activated At 2023-12-02 21:01:15 Device Association

The values aren't setup correctly as you have fan/heat/cold modes and auto/low/medium/high fan speed and they are not recognized fine.

Besides, the temperature is reduced x5 times, so I can't ever see the actual temperature nor set it correctly.

Steps to reproduce.

I tried the auto setup with no success. Then configured the modes etc. manually and they are fine now but the temperature is still reduced x5.

This is the debuggin result in tuya api platform:

Without device diagnostics I won't be able to understand anything...

[Hammerhand17]

Ok, do you need the full file or just the part that affects my thermostat?

[xZetsubou]

Post the JSON file of the diagnostics is enough.

[xZetsubou]

What do you mean by temperature is reduced by x5?

Also the configuration you made manually aren't the best. HVAC Modes:

off: false
heat: true

The fan speeds:

0,1,2,3

---

You can also add 1 more select platform entity tho I don't know what it that do: systemMode DP 102 The options should be

0: 0
1: 1
2: 2

[Hammerhand17]

It's as seen here: https://github.com/midstar/homeassistant_tuya_with_bht-002_support Or here: https://github.com/home-assistant/core/issues/72703

In smart life the modes are cold,heat,fan, and fan speed is auto, high,medium,low. Also you have manual, program and eco modes and child lock.

[xZetsubou]

The values in cloud are not the same values on local they are different in cloud it's kinda translated but in local it actually "0,1 etc ..."

To debug then further do one of this options.

1st Option: Monitor the DPS changes for the device

1. Go to Home Assistant -> Developer tools -> Events
2. Listen to one of these events localtuya_device_dp_triggered or localtuya_states_update
3. Go to Smart Life then Change the modes to Cold then change it To Heat Then change it Fan

---

2nd Option: Monitor using the logs: So to debug this more enable the debug for the integration and device as well reporting an issue note you can enable the debug from UI without need to restart HA then after enabling both them go to smart life and change the modes from cold to heat then to fan

You can re-add the device with auto configuration if you installed master version

Install Master Version

Go HACS -> Local Tuya -> On top right corner click on the ⋮ and choose redownload and select master  And restart HA then re-add your device

---

Manually adjust the existed configuration to:

Mode DP -> 102 HVAC Modes:

cool: "0"
heat: "1"
fan_only: "2"

FAN DP -> 103 FAN Speeds:

0,1,2,3

Preset DP -> 4 Presets:

"0": Program
"1": Manual

[Hammerhand17]

Ok, done and working fine, just the temperature error left: As you can see it shows 5,4ºC when It's really 27, and actual temperature shows 5,6ºC when it's really 28.

[xZetsubou]

Re-configure the device and change these

Precision (optional, for DPs values) -> 0.5 Target Precision (optional, for DP values) -> 0.5

[Hammerhand17]

Re-configure the device and change these

Precision (optional, for DPs values) -> 0.5 Target Precision (optional, for DP values) -> 0.5

Perfect, now it works as expected!! Thanks!

[Hammerhand17]

One more question: Can I start updating now to latest versions? it appears that I can update to 2024.5.0 but I don't want to lose the setup.

[xZetsubou]

The Master version are always ahead of any other version however I don't recommend to stick with it the changes fix a problems

for your case it was only configuration issue so it fine if you update to stable version 2024.5.0

[Hammerhand17]

Ok then, Thanks again for your work!

[gabrielhopkins]

Re-configure the device and change these Precision (optional, for DPs values) -> 0.5 Target Precision (optional, for DP values) -> 0.5

Thanks you very much - great integration @xZetsubou
