[Tuya] Daitsu Split Air conditioner DOSM-21KDT with TCWBRCU1(WBR3)(RTL) - T

How can I get an OpenBeken/TuyaAC driver working with a Daitsu DOSM-21KDT air conditioner and control it over MQTT?

Use Notupus’s OpenBK7231T TuyaAC driver rather than the generic TuyaMCU approach; the thread concludes that TuyaMCU does not fit this unit well [#21919462] After a full power-off/power-on of the AC indoor board, the TuyaAC driver starts reading the device correctly and most of the important values appear in the log, including power, temperatures, fan speed, mode, swing, eco, and other DPID data [#21922082] Control works through MQTT command topics such as `cmnd//ACPower`, `ACMode`, `FANMode`, and `TargetTemperature` [#21922082] One remaining issue is that fan states are not mapped perfectly: auto and mute are being shown/reported incorrectly in the UI/Home Assistant, so that mapping still needs correction [#21922082] [#21922494]

Tuya DPID mapping and UART traces captured

Post #1 21919441 11 Jun 2026 18:21

Hi,

As advice by some members I opened a separated thread as seem my TCL / tuya device is not matching exactly with the others ACs that has been reverse engineered so far. Here is what I have found so far.

The air conditioner is a Daitsu 3x multisplit that works with the Tuya smartlife app. It seems this machine is build by Gree.

Exterior units: Daitsu DOSM-21KDTInterior units: DS-18KZ & 2xDS-9KZ

USB plug circuit board next to a white Wi‑Fi/Bluetooth module label with certification marks

From the description of the USB module it says:
WIFI ad Blutoth ModuleMODEL(MODÉLE):TCWBRCU1
FCC ID:2ANDL-TCWBRCU1
IC:23243-TCWBRCU1
rt18720cf_voice_aircon_tcl_home_Ql0_1.0.60G0303-110084

Inside as expected the same WBR3 module. I added it to the tuya app, and I get to extract from the cloud api the DPIDs, model and all relevant information. I have also as suggested extract a boot log from the TX0_LOG in the original firmware, and also I have captured some traces form the UART that is sent to the AC from the WBR3.

First the Tuya Cloud info DPIDs

I did some diggings with Gemini and based on his replies I tried to configure the Openbeken to send thru channels the basic ON/OFF sequences but I failed badly to get any result. I was getting all the time:

The TuyaMCU driver will be of no use for this device. @notupus's work-in-progress build seen in their fork here https://github.com/Notupus/OpenBK7231T_App will need to be flashed - either by UART or OTA to it. The build files are under the actions here https://github.com/Notupus/OpenBK7231T_App/actions and require you to be logged into GitHub to download.

However, as it's in development, maybe it's not ready. Only notupus will know I guess. And even then their build may not cater for the additional dpIDs seen in your device.

As you can see the device use the same header seem in other devices A5 01.

I did some diggings with Gemini and based on his replies I tried to configure the Openbeken to send thru channels the basic ON/OFF sequences but I failed badly to get any result. I was getting all the time:

Info:TuyaMCU:Consumed 66 unwanted non-header byte in Tuya MCU buffer
Info:TuyaMCU:Skipped data (part) A5 01 01 21 42 00 00 42 46 F7 0C 0C 00 01 00 00 02 00 00 09 60 00 03 00 00 0B 0E 00 05 02 00 0C 01 00 0D 00 00 0E 08 00 11 01 00 12 01 00 DF 01 00 C9 00 00 17 00 00 1E 01 02 27 00 00 00 4B 01 48 00

The size of the 66 bytes change all the time like the traces are in variable size.

I tried with the Tuya driver and TCL, non of them work out of the box, that was the first thing I tried.

Below what Gemini seems to interpret of my initial tests. No idea if this is right or wrong.

1. Discoveries from the Boot Trace (Initial State)The boot sequence captures the air conditioner's baseline profile when waking up (configured at 21°C and Medium-Low Fan).
#Target Set Temperature Baseline (21°C):
Location: Offset 00000570
Raw Sequence: ... a5 01 00 21 08 00 00 48 26 15 15 ...
Discovery: The twin adjacent bytes 15 15 translate directly to 21 in decimal notation. This establishes how the MCU stores the initial comfort boundary.

#Ambient Air Sensor Baseline:
Location: Offsets 000004d0 & 000004e0 (Payload IDs 04 and 05)
Raw Sequence: ... eb 0b 0b ... and ... 38 0b 0b ...
Discovery: The recurring twin bytes 0b 0b represent 11 in decimal.
This serves as the raw index for the room's environmental probe resting around 21°C–22°C at boot.

#Initial Fan Speed Configuration (40%):
Location: Offset 000004b0 (Payload ID 02)Raw Sequence: ... a5 01 00 21 02 00 00 12 01 af 28 28
Discovery: The duplicate trailing bytes 28 28 equal 40 in decimal, mapping directly to a 40% Fan Speed (Medium-Low or Auto profile) initialized by the TCL comfort curve.

2. Discoveries from the App Interactions (ON vs. OFF)
When interacting via the Wi-Fi network, the payload changes from status reporting to execution commands, altering specific byte offsets.

#A. App Command ON (Set to Cooling @ 25°C)
Raw Sequence: ... a5 01 01 21 0b 00 00 12 eb 65 0a 0a 00 01 01 00 df 00
Temperature Target Shift: The target comfort zone shifted from the boot value of 15 15 (21°C) to 0a 0a (10 in decimal) to scale the compressor's inverter bounds for a 25°C app setting.

Power & Mode Registers: The trailing byte sequence 00 01 01 00 contains the active run flags:
01 (First): Inverter operation flag / Cooling mode enabled.
01 (Second): Power state set to ON.

#B. App Command OFF (Standby State)
Raw Sequence: ... a5 01 01 21 0c 00 00 0f 38 55 0a 0a 00 01 00
Power State Toggle: Comparing this directly to the ON frame, the trailing active run flags mutated down to 00 01 00.
*The second 01 dropped to 00, mapping directly to the Power OFF (Standby) state.

Mode & Temp Memory Retention: Notice that 0a 0a (25°C target) and the first 01 (Cooling mode) remain intact in the OFF payload.
This proves that the TCL MCU maintains the last used settings in volatile memory while sleeping, ensuring it knows its target state upon the next wake cycle.

3. Infrastructure and Signal Maintenance (Type 23 Commands)Throughout all running logs, the constant background ping loop (01 23) contains telemetry for wireless health.

Wi-Fi Signal Strength (RSSI):Raw Sequence: ... a5 01 00 23 00 00 00 12 05 9d 80 0c 02 64 ff ff ff c5

Discovery: The isolated byte 64 translates to 100 in decimal, revealing that the WBR3 uses this specific byte block to broadcast a 100% Wi-Fi Signal Link back to the main control unit.

I can take traces and do all tests needed, but openbeken is new to me, and my developer skill are very limited. Any help is most welcome.

Hi @divadiow,

I was going thru the code from notupus and I get to start the driver from @notupus with Startdriver TuyaAC.

Seems something is not matching to my AC as all figures in the UI look empty when I interact with the remote.

In the logs I see a loop reporting indefinitely

not really sure. maybe yours is different enough that the TuyaAC driver is still not the right fit. Maybe it is and yours is a different baud?

Did you run your backup through Easy Flasher Tuya config extractor to see what baud it shows, if any?

Power cycle restored AC UART communication
Post #8 21919991 12 Jun 2026 16:15

Well, some developments, strange ones, after I loaded the Notupus firmware.

My WBR3 was refusing to load drivers and every time I tried it manually, it crashed and rebooted. So, I cleaned all conf in the module in case any conf was wrong, and I left it vanilla. It kept happening. I uploaded the standard version of openbek and same. So at that point I thought the module is fried, or the AC CPU or AC UART controller crashed somehow because of the flood.

Seems the firmware from notupus crashed my internal board. I cut the power to the AC completely for 1 minute, reverted it back, and then the Tuyamcu driver and all others started working again, allowing.

Now comes the strangest of all things. Now if I load the TCL generic driver, which did not work initially, and if I click on change mode in the UI from off to 1, it works. Well, sort of works, it sends something and I hear the beep in the AC and it switches on, what mode or what it does, no idea.

However, it is not updating the temps or other values in the UI, so I guess at least the mode change is sending a DPID that the AC recognizes behind TCL driver.

One more thing to note is I don't see error logs in the openbeken log about header not recognized, so the complete shutdown of the AC must have done something to the AC CPU. That was different when the original Tuyaclod firmware was plugged in. Maybe the tuya firmware change or adjust something on boot on the device and change its behaviour.

So based on what I have seen, if I add my DPIDs to the standard tcl it should work???

Power cycle fixed AC board hang and restored telemetry
Post #12 21922082 16 Jun 2026 00:52

I loaded the new version, and...

Pretty much the same result just a list of things that show 0 or Off like is not reading. I started the driver with the command startdriver tuyaac but nothing.

Also I don't see any reaction on the LOG when i send commands with the remote neither, not sure if it is expected.

Well when I load the driver I see this

Info:MAIN:Starting tuyaAC.
Info:TuyaAC:TX UART: LEN=13 CRC=0x0805 A5 01 00 21 03 00 00 0D 08 05 00 00 01
Info:TuyaAC:TX UART: LEN=14 CRC=0x0257 A5 01 01 21 04 00 00 0E 02 57 0B 0B FF FF
Info:MAIN:Started tuyaAC.

but nothing afterwards. just wifi messages. That HEX with the FFFF should ask the machine to send back the parameters to fill the UI info, but that is clearly not happening,

UPDATE!!!

Added after 49 [minutes]:

Well, you will not believe it, same happen again, my AC was hanged, the internal board I guess, so I was not seeing anything.

I did a complete power off and on again, that rebooted the AC board, and all of a sudden on a fresh boot:

So that was success.

Now I get almost all parameters, at least all relevant ones. I have detected a minor error, Fan Mute is detected as lowest, instead of mute, and mute detected as lowest, they are exchanged.

I'm trying to sent the commands over Mqtt but seems that i can not make it work.

I'm sending
mosquitto_pub -h x.x.x.x -t "nameofdevice/mute/set" -m "On"

Info:MQTT:MQTT client in mqtt_incoming_publish_cb topic nameofdevice/mute/set
Info:MQTT:MQTT client in mqtt_incoming_data_cb data is off for ch 0
Info:GEN:No change in channel 0 (still set to 0) - ignoring

I received all parameters in the mqtt stream but i'm not sure how to send them back to change parameters, i assume is with /set but this seems to not work, maybe is not fully implemented in notopus firmware still.

Added after 20 [minutes]:

OK, checking Notopus code I see he has implemented for now only:

CMD_RegisterCommand("ACMode", CMD_TuyaAC_Mode, NULL);
CMD_RegisterCommand("FANMode", CMD_TuyaAC_Fan, NULL);
CMD_RegisterCommand("TargetTemperature", CMD_TuyaAC_TargetTemp, NULL);
CMD_RegisterCommand("ACPower", CMD_TuyaAC_Power, NULL);

I was able to control all those sending a mqtt message like:
mosquitto_pub -h x.x.x.x -t "cmnd/devicename/FANMode" -m "mid"

That works.

One question that comes to my mind is if your modification made it work, or it was my AC CPU hanged again. I need to load Notopus version to validate if that is the case or not, but at least we have some good progress :)

One strange thing, or maybe is mapped incorrectly in notopus UI, is that in the log it says:

which is correct, but in the Wen UI it is shown as

Auto fan mode is misreported as mute
Post #14 21922453 16 Jun 2026 15:12

Thanks @divadiow, I tested but I see some strange behaviors.

I reverted back to the Notopus original version to start from there again.

Let's focus on the Fan mode for now.

Fan mode AUTO:
If I send auto from the remote the log shows correctly auto. If I sent Auto from MQTT, it shows also auto in the log; however, in the WEB UI it is reflected as MUTE. The problem with this is that MQTT reports also MUTE back to Home Assistant even when the log is showing auto, that means this reflects the wrong mode in the Home Assistant UI. So this need to be remapped. I guess is a bug in Notopus code.

Fan Mode Mute:
This one has been assigned to mode LOWEST in Notopus firmware, I think he did that to match the lowest value from Home Assistant, so I think this one is fine even if it is called lowest instead of mute. Not sure if Home Assistant allows to add mute as a fan mode.

this should have changed what should be exposed/reported as fan state versus mute state. did you do HA discovery in OBK after flashing?

I loaded it again, and when I hit auto it shows fan mute, and mute ON instead of auto.

Auto mode misreported as fan mute in MQTT UI

Post #18 21923021 17 Jun 2026 12:27

Auto discovery does not work.

I did it manually. That way it works, but as I said, when I hit auto it shows fan mute, and mute ON instead of auto. When I choose mute it is identified as lowest, fine, but the auto is not recognize as there is a bug in the Web UI and mqtt get that sends mute for auto.

Topic summary

✨ Discussion about reverse engineering a Tuya/Smart Life Wi‑Fi air conditioner controller for a Daitsu 3‑split system (likely Gree-built) using a TCWBRCU1 / WBR3 module. The device did not match existing TuyaAC schemas: the Daitsu DOSM-21KDT shared many dpIDs with a Nordstar NORX-10CHSD profile but also had unique IDs and different behavior. Firmware logs from the RTL8710C-based module were extracted, and several OpenBK7231T/TuyaAC firmware builds were tested. Initial attempts produced empty UI values, repeated “Garbage RX: 00” messages, and no proper response to remote commands. Later testing showed partial control: some mode changes triggered AC beeps and power-on, but temperature and state reporting remained incorrect. The thread focused on dpID mapping fixes, baud-rate/config extraction, and correcting fan/mute/eco handling, especially the confusion between AUTO and MUTE states in Home Assistant and the web UI.

[Tuya] Daitsu Split Air conditioner DOSM-21KDT with TCWBRCU1(WBR3)(RTL) - T

FAQ

TL;DR: With 77 shared DPIDs and “The TuyaMCU driver will be of no use,” this FAQ helps Daitsu DOSM-21KDT owners on WBR3/TCWBRCU1 get OpenBeken working by using the TuyaAC test driver, power-cycling the AC when the indoor board hangs, and mapping TCL-style DPIDs instead of generic TuyaMCU frames. [#21919462]

Why it matters: This thread shows the difference between a dead-end generic flash and a working OpenBeken setup that reports temperatures, mode, fan state, and accepts core MQTT commands.

Option	What happened on DOSM-21KDT	Best use
Standard TuyaMCU driver	Rejected frames with non-header/skip errors	Not recommended for this AC
TCL generic driver	Could beep and power on, but status stayed incomplete	Quick proof of partial compatibility
TuyaAC test build	After full AC power reset, reported most key values and accepted core commands	Best current choice

Key insight: The main blocker was not only firmware selection. The indoor AC board could hang after flashing, and a full mains power-off for about 1 minute was the step that restored UART communication and let TuyaAC start reading live data. [#21919991]

Quick Facts

The Daitsu setup uses a TCWBRCU1 Wi‑Fi/Bluetooth module with WBR3 inside, and the original firmware log shows RTL8710C, build date Oct 15 2025, and UART baud 115200. [#21919471]
The extracted Tuya Cloud profile reports category "kt", model "Artic", product ID ytdek3ddm6hlig7r, and temperature limits of 16.0°C to 31.0°C via DPIDs 114 and 113. [#21919441]
Compared with Nordstar NORX-10CHSD, this Daitsu shares 77 DPIDs and has 18 unique IDs, so reuse is possible but not drop-in compatible. [#21919462]
Once TuyaAC began working, live values included target 23.0°C, current 20.3°C, outdoor 25.0°C, indoor fan 1900 RPM, and compressor 0 Hz in one captured status set. [#21922082]

How can I get a Daitsu DOSM-21KDT air conditioner with a TCWBRCU1/WBR3 module working with OpenBeken?

Use a TuyaAC-capable OpenBeken test build, not the standard TuyaMCU driver. The working path in this thread was: 1. OTA flash the TuyaAC test firmware to the WBR3. 2. Start it with startdriver tuyaac. 3. If nothing reads, cut AC mains power for about 1 minute and boot again. After that reset, the UI began showing key values and MQTT control worked for ACPower, ACMode, FANMode, and TargetTemperature. [#21922082]

Why does the OpenBeken TuyaMCU driver show "Consumed unwanted non-header byte" and skipped A5 01 frames on this Daitsu/TCL air conditioner?

It happens because this AC does not speak the simple TuyaMCU format the generic driver expects. The module sends TCL/Tuya AC packets with an A5 01 header, variable lengths, and grouped status payloads, so the standard parser treats leading bytes as garbage and logs skipped data. The thread also states directly that “The TuyaMCU driver will be of no use for this device,” which matches those header and buffer errors. [#21919462]

What is the TuyaAC driver in OpenBeken, and how is it different from the standard TuyaMCU driver for air conditioners?

"TuyaAC" is a specialized OpenBeken driver that parses TCL-style air-conditioner UART packets, grouped status reports, and AC-specific commands, unlike the generic TuyaMCU driver that expects simpler datapoint traffic and fixed framing. On this Daitsu, TuyaAC sent A5 01 00 21 and A5 01 01 21 packets, then later decoded live values like 23.0°C target and 1900 RPM fan speed. The generic TuyaMCU driver did not. [#21922082]

What are Tuya DPIDs, and how do I use the cloud-extracted DPID list to map functions on a Daitsu or TCL AC?

"DPIDs" are Tuya datapoint identifiers that link each device function to a numeric ID, data type, and value, letting you match power, mode, temperature, fan, and telemetry fields between cloud data and UART traffic. For this AC, cloud data exposed DPID 1 power, 2 set temperature, 3 current temperature, 4 mode, and 5 fan speed. You use that list to compare UART reports and rename or remap fields in TuyaAC or TCL-specific code. [#21919441]

Which differences between the Daitsu DOSM-21KDT and the Nordstar NORX-10CHSD DPIDs matter when adapting @notupus's TuyaAC work?

The important difference is not the shared base but the missing extras. The thread says the Daitsu shares 77 DPIDs with the Nordstar but has 18 unique differences, while the Nordstar has extra IDs such as 157–172 and 195–196 for 3D wind, anti-direct-blow, solar, and OpenADR functions. That means TuyaAC logic can be reused, but unsupported fan, airflow, and energy features need new mapping or can stay unimplemented. [#21919462]

How do I extract the UART baud rate and Tuya config from a WBR3 backup using Easy Flasher Tuya config extractor?

Run the saved WBR3 backup through Easy Flasher’s Tuya config extractor and check whether it reports UART settings. In this thread, that step was suggested specifically to confirm whether the AC used a different baud. The original firmware boot log later confirmed read baud rate 115200, so the extractor is useful as a fast cross-check before changing driver assumptions. [#21919984]

Why does the TuyaAC UI stay empty and log repeated "Garbage RX: 00" messages after starting the driver?

The usual cause here was a hung AC indoor board, not a dead WBR3. After one flash, the UI stayed blank and logged repeated Garbage RX: 00, but a full power cut to the air conditioner restored communication. On the next cold boot, TuyaAC began receiving status and populated most fields. If the UI is empty, power-cycle the whole AC first, then retry startdriver tuyaac. [#21919752]

What is the meaning of the A5 01 UART header seen in TCL/Tuya air conditioner traces, and how should those packets be decoded?

A5 01 is the packet header for this TCL/Tuya AC UART protocol, not proof of compatibility with the generic TuyaMCU parser. The thread’s traces show frames such as A5 01 01 21 A2... and A5 01 01 21 A3..., where the payload carries multiple datapoints in one report. Decode them as framed TCL/TuyaAC packets: header, direction/type, command class 21, length, CRC, then packed ID/value pairs. [#21922082]

When an AC stops responding after flashing OpenBeken or a custom TuyaAC build, what recovery steps should I try before assuming the board is damaged?

First, do not assume the board is fried. In this thread, the AC stopped reacting, drivers crashed, and the module kept rebooting, but the fix was simple: 1. Remove power from the entire air conditioner. 2. Leave it off for about 1 minute. 3. Reapply power and test again with a clean or known-good build. That reset cleared the hang and brought back UART behavior that earlier seemed broken. [#21919991]

How do I OTA flash @notupus's OpenBK7231T_App test build onto a WBR3 module, and what should I expect on first boot?

Use the GitHub Actions build artifacts from the test branch and flash the OTA file to the WBR3. On first boot, do not expect a ready-made UI with channels already populated. One user reported the module booted normally after OTA, but “the UI is not showing any channels configured or anything.” You may need to start the driver manually and, if the AC board is stuck, power-cycle the air conditioner before data appears. [#21919484]

TuyaAC vs TCL generic driver vs standard TuyaMCU driver — which one is the right choice for a Daitsu DOSM-21KDT built on a TCL/Gree platform?

Choose TuyaAC first, use TCL generic only as a partial test, and avoid standard TuyaMCU for final use. On this DOSM-21KDT, TuyaMCU failed on headers, the TCL generic driver could beep and switch the unit on, but did not update temperatures or status, while TuyaAC eventually read most live parameters after a full AC reset. That makes TuyaAC the best fit for this TCL/Gree-style platform today. [#21919991]

How can I control ACMode, FANMode, TargetTemperature, and ACPower over MQTT in @notupus's TuyaAC firmware?

Use command topics, not /set state topics. The working format was cmnd/devicename/FANMode with payloads like mid, and the code currently implements only four commands: ACMode, FANMode, TargetTemperature, and ACPower. A direct test using nameofdevice/mute/set failed and was ignored, but mosquitto_pub -h x.x.x.x -t "cmnd/devicename/FANMode" -m "mid" worked. [#21922082]

Why do some fan modes appear swapped in the TuyaAC web UI, such as Mute showing as Lowest and Lowest showing as Mute?

The likely cause is incorrect enum mapping in the driver UI, not a hardware failure. The user observed that Fan Mute was detected as Lowest and Lowest as Mute, while the logs still parsed valid fan-related values. Later, the log showed Fan Speed Mode: auto even when the web UI displayed Fan: mute, which points to a label or index mismatch between received DPID values and displayed fan names. [#21922082]

What does the boot log reveal about the TCWBRCU1/WBR3 module, including baud rate, MCU ID, firmware version, and cloud model matching?

The boot log is rich enough to fingerprint the setup. It shows RTL8710C hardware, WBR3-class firmware, read baud rate 115200, app string tcl_voice_aircon:1.0.60, and MCU identification V9-R10FT27AC-FV with version 001.001.030. It also shows cloud matching against channels 9 and 10, plus a Tuya product key and firmware key, confirming this is a TCL-style cloud-linked AC implementation rather than a plain TuyaMCU device. [#21919471]

If the TCL generic driver can beep the AC and turn it on but does not update temperatures or status, how should I add or remap DPIDs to make it fully work?

Treat that beep as proof of partial command compatibility, then remap the DPID set to this AC’s schema. Start from the known working core IDs: 1 power, 2 target temperature, 3 current temperature, 4 mode, 5 fan, 31 vertical, 34 horizontal, 111 AI eco, 113 upper limit, and 114 lower limit. The thread’s conclusion was that if TCL generic can actuate the unit, adding this device’s DPIDs to the standard TCL/TuyaAC mapping is the next practical step. [#21919991]
