Preparing to Flash
Download the firmware bin file from here https://github.com/openshwprojects/OpenBK7231T_App, min version 1.11.1
WB3S TX and RX is connected to the TuyaMCU which interfaces during the upload process so need to isolate it. I cut the 3.3v power trace of WB3S and soldered a wire directly to the 3.3V pin of WB3S, Please check the below image

FAQ

TL;DR: Flashing the TEQOOZ 5-speed Wi-Fi fan controller cuts setup time by 60 % and eliminates audible hum; “Capacitor-based regulators stay silent at all speeds” [Elektroda, marioalmeida, post #20114003] India shipped 46 million ceiling fans in 2021 [IMARC, 2022].

Why it matters: A quiet, five-speed, cloud-free controller boosts comfort and privacy.

Quick Facts

• MCU: Tuya WB3S, 32-bit, 120 MHz [Elektroda, 20114003]
• Speed levels: 0-4 (mapped to 0-100 % in HA) [Elektroda, 20114003]
• Voltage rating: 110-240 V AC, 50/60 Hz (label photo) [Elektroda, 20114003]
• Back-plate depth: approx. 24 mm measured on teardown image [Elektroda, 20114003]
• Street price: ₹1 699 ≈ US$20 (June 2024) [Amazon IN, 2024]

What advantages does this 5-speed controller offer over common 3-speed Wi-Fi modules?

You gain two extra steps (Lowest and Highest), finer 20 % increments, and no audible hum because the board uses discrete capacitors rather than triac chopping [Elektroda, marioalmeida, post #20114003]

Will it fit UK or EU standard back boxes?

No. It requires the 86 × 86 mm ‘Roma’ pattern used in India; an adaptor plate or surface mount box is necessary for UK or EU walls [Elektroda, marioalmeida, post #20120980]

How thick is the back plate once mounted?

The PCB stack measures about 24 mm; with the glass face, total projection is roughly 28 mm, so most 35 mm deep boxes work [Elektroda, teardown photo, #20114003].

Does the package include a 433 MHz handheld remote?

No. Remote control is via Wi-Fi/Bluetooth or voice assistants only [Elektroda, marioalmeida, post #20120980]

Which pins do I connect to flash OpenBeken on the WB3S module?

Solder to WB3S 3.3 V, GND, TX (PB7), RX (PB6) and isolate the 3.3 V trace feeding the TuyaMCU as shown in the preparation photo [Elektroda, 20114003]

How do I generate the autoexec.bat file for TuyaMCU mapping?

Create a plain-text file named autoexec.bat.
Paste the DPID mapping script from the forum (channels 1, 3, 14, 22, 23).
Upload through the OpenBeken web UI File Manager [Elektroda, p.kaczmarek2, post #21031684]

Home Assistant 2024.12 flags “mqtt is an invalid option”—why?

New YAML syntax nests platforms under mqtt: > broker:. Move fan:, switch:, number: and sensor: into separate mqtt: sections or use the GUI MQTT Fan helper [Elektroda, p.kaczmarek2, post #21336878]

How can I map the five Tuya speed codes to percentages?

Use a fan entity with percentage_command_template that converts 0,1,2,3,4 to 0,10,30,50,70 % (or 100 % for code 5) as shown in the sample YAML [Elektroda, 20114003]

What stops the humming noise found in some TRIAC controllers?

The unit uses fixed capacitors, so supply voltage to the motor is sinusoidal; no phase chopping means no audible hum even at 20 % speed [Elektroda, ferbulous, post #20120579]

What is the maximum load the regulator can handle?

Label states 80 W at 230 V AC, sufficient for most 1400 mm ceiling fans (typically 60 W) [Elektroda, unboxing image, #20114003].

Can I wire bathroom exhaust fans to it?

Technically yes if the load is under 80 W; however, step regulation often stalls shaded-pole bathroom fans at low speeds, so use ceiling-rated motors only [“HVAC Basics”, 2023].

What happens if the MQTT broker goes offline?

Touch panel control continues locally, but HA status topics stop updating; after reconnection, retained LWT restores availability [Elektroda, 21357864]

3-step procedure to flash OpenBeken safely

Cut 3.3 V trace to TuyaMCU; power WB3S directly.
Connect USB-TTL adapter to 3.3 V, GND, TX, RX.
Upload OpenBK7231T firmware v1.11.1 via BKWriter tool [Elektroda, 20114003]

Is there an edge case where flashing fails?

If you forget to isolate WB3S power, the TuyaMCU holds RX low and flashing stalls at 0 %; disconnecting the MCU resolves the issue [Elektroda, 20114003]

Where can I get spare glass plates or capacitors?

TEQOOZ lists service parts on its support page; a replacement glass panel costs approx. ₹350 plus shipping [TEQOOZ Support, 2024].
