TEQOOZ Smart Fan Regulator Wi‑Fi + Bluetooth Touch Switch is adapted into a Home Assistant ceiling-fan controller with Tuya/Smart Life app control and Indian Roma fitting support.
WB3S firmware is flashed with OpenBK7231T_App after isolating TuyaMCU TX/RX by cutting the 3.3V trace and wiring the WB3S directly to 3.3V.
autoexec.bat starts the TuyaMCU driver and maps channels 1, 3, 14, 22, and 23 for fan power, five speeds, child lock, countdown, and remaining timer.
Home Assistant MQTT YAML exposes the fan, countdown, child lock, and IP, while template switches and an automation keep the reported fan speed synchronized.
Generated by the language model.
TEQOOZ® Smart Fan Regulator Wi-Fi + Bluetooth Touch Switch (White) | Capacitor Based – No Humming Sound | Tuya & Smart Life App Control | Compatible with Alexa, Google Home, Apple Siri | Glass Finish
This Fan controller is suitable for Indian homes with Roma fitting
Product information MOBILE APP CONTROL: Apart from physical touch, this switch can also be used from anywhere in the world using “Smart Life” App. Live status of the Fan can also be checked on the App. This switch gives 5 speed options and can operate any type of Fan.
SMART SCENE: You can create Smart Scenes to operate multiple devices at one go. Just add the devices in one group and operate them together. E.g. “Welcome Home” scene to Turn on the Fan & Turn on the Lights, etc.
HANDS-FREE VOICE CONTROL: Teqooz WiFi Switch is compatible with Amazon Alexa (Amazon Echo/Echo Dot/Amazon Tap), Google Assistant, & Apple Siri. So you can control your devices through voice and enjoy hands-free experience.
GLASS FINISH: GREAT LOOKS & Stylish Aesthetics add Glamour to the Décor of the room.
TIMER & SCHEDULING FUNCTION: Teqooz Smart Switches allow you to schedule device operations as per your choice / routine. E.g. Set Fan Speed to Maximum at 4 am. Turn off the Office Fans at 7 pm everyday, etc.
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

This is a controller intended to control ceiling fans, not bathroom fans (in Polish reality ;-) )

Thanks for this @marioalmeida
Does it fit for standard uk switch and how thick is the back plate?
Also, does this come with 433mhz remote?

No, you would need this kind of fitting which is very common in Indian homes

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, post #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, post #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]
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?
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]
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].
