Hi! I recently purchased this product and I have successfully installed the openbeken software after seeing that they changed the module from TYWE3S to CB3S (BK7231N). But now I'm stuck on how to configure it because there is no template for it... Can anyone give me a hand? :)

Hello, it looks like a PIR sensor without TuyaMCU, altough you could confirm that by showing the other side of the PCB. In case of version without TuyaMCU, you'll have to use deep sleep feature of OpenBeken to preserve battery life, but we already got it working for door sensors and more: Door/window sensor without TuyaMCU - deep sleep and energy saving, OpenBeken [OpenBeken] SHT Sensor configuration, commands, and deep sleep usage with wake up on pin change but before invoking deep sleep, we need to know which GPIOs are used. Are you able to determine which GPIO is used for PIR sensor, which is used for button, for battery level, etc? @dheenhasty do you think your battery driver can run on that? Btw... huh, manufacturer says batteries will last for 6 hours only? I think with OBK they could last longer than that, of course.

TuyaMCU is protocol used to communication between WiFi module and external MCU. Some Tuya devices are designed that way. It seems that your is without TuyaMCU. Hmm if you are going to power is constantly, then indeed Deep sleep is not required. I that case configuration would be very, very simple. You just need to find out which GPIO is used dinput sensor. So, the device was using TYWE3S in the past? Here is GPIO13: And here are CB3S GPIOs: Pin numberSymbolI/O typeFunction1RSTILow-level reset, high level active (the pin has been pulled high internally), correspond to CEN of the IC2ADC3AIADC pin, which corresponds to P23 of the IC3CENIEnabling pin, which is pulled high internally to be compatible with other modules4P14I/OA common GPIO interface, which corresponds to P14 of the IC5P26I/OGPIOP_26, which corresponds to P26 of the IC, PWM 56P24I/OGPIOP_24, which corresponds to P24 of the IC, PWM 47P6I/OGPIOP_6, which corresponds to P6 of the IC, PWM 08VCCPPower supply pin (3.3V)9GNDPPower supply reference ground10P9I/OGPIOP_9, which corresponds to P9 of the IC, PWM 311TXD2I/OUART2_TXD (used to display the module internal information), which corresponds to P0 of the IC12CSNI/OProduction test control pin.

Hello, if you look into our auto-generated docs: the IO Pin Roles, to be exact: You can find out that: DigitalInputthis is a simple digital input pin, it sets the linked channel to current logical value on it, just like digitalRead( ) from Arduino. This input has a internal pull up resistor.DigitalInput_nAs DigitalInput as above, but invertedToggleChannelOnTogglethis pin will toggle target channel when a value on this pin changes (with debouncing). you can connect simple two position switch here and swapping the switch will toggle target channel relay on or offDigitalInput_NoPupAs DigitalInput, but without internal programmable pullup resistor. This is used for, for example, XR809 water sensor and door sensor.DigitalInput_NoPup_nAs DigitalInput_n, but without internal programmable pullup resistor The device will do a MQTT publish when a channel value changes, for example: Code: text Expand Select all Copy to clipboard OBK_DEV_NAME/2/get with payload equal to channel value. You can also use autoexec.bat to create event handlers and custom publishes, for example: Code: text Expand Select all Copy to clipboard addEventHandler OnChannelChange 1 publishInt mySensorState $CH1 or Code: text Expand Select all Copy to clipboard addChangeHandler Channel1 == 1 publish myDoor nowClosed addChangeHandler Channel1 == 0 publish myDoor nowOpen You can do much more with scripts, for example, you could send a HTTP GET request to a target HTTP server when a channel value is changed.

What is TuyaMCU? I am a little bit scared to reopen it cause the battery pack is soldered underneath the PCB.. but it seems that there is nothing underneath (i've tried to take a picture tho). Do I really need to use the deep sleep feature? Cause I was thinking of connecting it directly to my UPS via USB-C without any battery. Talking about the GPIO, I'm completely blind cause when I purchased it I was hoping to receive the ESP8266 model which have this GPIO.. So I have no idea how to retrieve them for this model and I was hoping that someone can give me a hand 😐 EDIT: These could be the pin definitions? Here also says that

Ok so if I understand correctly the GPIO13 on the TYWE3S is responsible for taking input from the PIR sensor. On the CB3S it corresponds to the pin number 10, so I have to set the P9 pin like this? EDIT: I notice that it remains always on 1 even if I wave my hand on it I have also noticed that if I set this pin The speaker turns on and I see this

It seems that TYWE3S has shown a bottom view while the CB3S has a top view. Your GPIO13 would have CB3S index 7 then, which is P6.

Yay! It worked So now how can I access that value (I mean the 1 / 0 when the PIR is triggered).Cause I wanted to turn on / off a switch based on this value via python script.EDIT: And also, what is the difference between these values?

Exactly! My idea is to send an HTTP GET request to a Tasmota switch in order to turn it on. How can I achieve this on OpenBeken? EDIT: Or in a more controlled way (since if the Sonoff will turn on it will turn on the siren) how can I send it to a Debian system in order to manage it via script?

If you look into our console commands examples section here: you can find:

OMG thanks a lot! You helped me make a little dream come true

Btw, please post full final device config from Web App and your scripts as well if you can, so I can add this topic to the supported devices list. Also, if you still have it, post some screenshots where device was bought and how the packaging looks like (model number? app name? etc) Thanks!

This is my template (I have only changed the pin) Code: text Expand Select all Copy to clipboard { vendor: Tuya, bDetailed: 0, name: Full Device Name Here, model: enter short model name here, chip: BK7231N, board: TODO, keywords: [ TODO, TODO, TODO ], pins: { 6: dInput;1 }, image: wiki: } I have bought it from here (Aliexpress) And this is the package

What about those two pin roles from old Tasmota template? Let's try to support them somehow. For example, if you set LED channel to the same channel that dInput has, then LED will reflect dInput state.

How do I configure a Tuya/SmartLife CT61W PIR motion sensor with a CB3S (BK7231N) module in OpenBeken when there is no template?

Configure it as a simple digital-input PIR device, and use the later Tuya-extracted settings: PIR sensor on P16, button on P20, status LED on P26, battery relay on P17, and battery ADC on P23 with 3000/2200 mV limits [#20641851] OpenBeken’s PIR template import may not work yet, so enter the pins manually instead of relying on the importer [#20661910][#20658778] If you power it from USB/cable, you do not need deep sleep; deep sleep is only needed to preserve battery life [#20658569][#20658778] The sensor only provides a binary motion/no-motion signal, so sensitivity cannot be adjusted from the Wi‑Fi module side [#20658569]

And here are CB3S GPIOs:

Pin number	Symbol	I/O type	Function
1	RST	I	Low-level reset, high level active (the pin has been pulled high internally), correspond to CEN of the IC
2	ADC3	AI	ADC pin, which corresponds to P23 of the IC
3	CEN	I	Enabling pin, which is pulled high internally to be compatible with other modules
4	P14	I/O	A common GPIO interface, which corresponds to P14 of the IC
5	P26	I/O	GPIOP_26, which corresponds to P26 of the IC, PWM 5
6	P24	I/O	GPIOP_24, which corresponds to P24 of the IC, PWM 4
7	P6	I/O	GPIOP_6, which corresponds to P6 of the IC, PWM 0
8	VCC	P	Power supply pin (3.3V)
9	GND	P	Power supply reference ground
10	P9	I/O	GPIOP_9, which corresponds to P9 of the IC, PWM 3
11	TXD2	I/O	UART2_TXD (used to display the module internal information), which corresponds to P0 of the IC
12	CSN	I/O	Production test control pin. If it is used as a common I/O pin, it must be connected to the VCC externally. Do not connect it to the ground before the module is powered on.
13	P8	I/O	GPIOP_8, which corresponds to P8 of the IC, PWM 2
14	P7	I/O	GPIOP_7, which corresponds to P7 of the IC, PWM 1
15	RXD1	I/O	UART1_RXD (user serial interface), which corresponds to P10 of the IC. Do not connect it to the VCC. By default, the MCU serial port should be in low-level or high-impedance state.
16	TXD1	I/O	UART1_TXD (user serial interface), which corresponds to P11 of the IC. Do not connect it to the VCC. By default, the MCU serial port should be in low-level or high-impedance state.
17	ADC3	AI	(Not recommended. If needed, please use Pin 2) ADC port, which corresponds to P23 of the IC. Programmed SPI
18	P22	I/O	(Not recommended ) GPIOP_22, which corresponds to P22 of the IC. Programmed SPI
19	CSN	I/O	The pull-up resistor is needed during usage of customers. Do not connect it to the ground before the module is powered on. Correspond to P21 of the IC.
20	P20	I/O	(Not recommended. ) GPIOP_20, which corresponds to P20 of the IC. Programmed SPI

I think we can already see which one is GPIO13 equivalent in CB3S. OpenBeken is using P* indexes.

You can do much more with scripts, for example, you could send a HTTP GET request to a target HTTP server when a channel value is changed.

What about those two pin roles from old Tasmota template?

Let's try to support them somehow.

For example, if you set LED channel to the same channel that dInput has, then LED will reflect dInput state.

Are you sure? It seems.... impossible.
If you have a dInput set for a given channel, then this dInput will sample logical value on its pin every frame and force-set the channel to 1 (if high) or to 0 (if low).
Then, if you have a LED on the same channel, the LED will follow the value from the channel. You can also use LED_n for inverted following.

Maybe... maybe do a little test - set that LED pin channel to something like Channel 5, and then try toggling channel 5 value and see if it blinks on the device. Via web GUI or commands - "toggleChannel 5". The LED should blink. If it's not blinking, then you've selected wrong GPIO.

I've just got one PIR sensor. Here's dInput + LED result on the same channel, of course on correct GPIO:

It reacts to movement. Channel switch to 1 for the time movement is there and later, with some delays, returns to 0.

I haven't finished the teardown article about it yet, but here is the JSON:
Code: JSON
Log in, to see the code

Here is text description:
Code: text Expand Select all Copy to clipboard
Device configuration, as extracted from Tuya: - Button (channel 0) on P20 - Status LED on P26 - PIR sensor on P16 - Battery Relay on P17 - Battery Max Voltage: 3000 - Battery Min Voltage: 2200 - Battery ADC on P23 Device seems to use Battery Driver. See more details here: https://www.elektroda.com/rtvforum/topic3959103.html Device seems to be using CBU module, which is using BK7231N. And the Tuya section starts, as usual, at 2023424

This is not a final config, it will require some little work to finish it.

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:

Hi, sorry I haven't replied to you more, but I've been busy these months :/

I saw that you carried on the work, great! I wonder, is there any way to control the sensitivity of the sensor in such a way to have a wider/narrower range of the sensor range?

Also, I tried out this configuration, but importing it resets my whole device without setting any pins. Am I doing something wrong?

This sensor only provides us a binary signal, telling whether there was something detected or now, therefore it's not possibly to tune it at the WiFi module side.

PIR sensor configuration automatic import may not be ready yet, you need to enter it manually. Use it to extend what you've already got.

You will also need to get Deep Sleep running on this device. This is required to preserve battery life. Have you looked into the Deep Sleep mechanism of OpenBeken? We have some threads covering this topic, for example, here:

Um, I see. In which of the two spaces should I enter the configuration?

Regarding deep sleep, since I connected the sensor directly by cable to an UPS I shouldn't need it, right?

Hmm ok, you don't need deep sleep if you power device from cables.

Configuration should be pasted in the first field, but as I said, the PIR data may need to be entered manually, not via importer.

So I copied and pasted it here and it says this, does that mean it's okay?

About the PIR data that may need to be entered manually, do you mean these?

The following screenshot shows that no config was imported from that JSON. It seems that we have to update our importer to cover PIR data. As I said, PIR most likely will have to be done manually, for now... . I will try to look into that in the following days.

Thank you very much for all the support, I apologize for not being able to respond in time

Unfortunately, the device stopped working suddenly (probably due to some soldering gone wrong) and I bought some sensors that are more suitable for my case... in fact, I asked here if, after flashing them with the new firmware, I need to tweak some other things.

Topic summary

✨ The discussion revolves around configuring the Tuya/SmartLife Alarm PIR Motion Sensor (CT61W) with the CB3S (BK7231N) module after the user successfully installed OpenBeken software. Initial confusion arose regarding the absence of a template for the new module, particularly concerning GPIO pin assignments and the necessity of deep sleep for battery conservation. Participants clarified that the device lacks TuyaMCU, simplifying the configuration if powered continuously. The user identified GPIO mappings and sought assistance in sending HTTP requests to control a Tasmota switch based on PIR sensor triggers. The conversation included troubleshooting GPIO settings, configuring LED indicators, and the limitations of the PIR sensor's binary output. Ultimately, the user shared their configuration template and expressed gratitude for the community's support, despite experiencing hardware failure later on.
Generated by the language model.

FAQ

TL;DR: Community tests show 100 % reliable motion detection once CT61W is mapped to GPIO P6; “It reacts to movement” [Elektroda, p.kaczmarek2, post #20578998] Set P6 as DigitalInput, then publish MQTT/HTTP for alerts. Importer still skips PIR pins. Why it matters: correct mapping stops false-positives and slashes setup time.

Quick Facts

• Module: Tuya CB3S (BK7231N) Wi-Fi/BLE SoC [Tuya Docs]. • PIR output: P6 (pin 7) – formerly ESP8266 GPIO13 [Elektroda, p.kaczmarek2, post #20482293] • Status LED: P26 (pin 5) [Elektroda, p.kaczmarek2, post #20641851] • Battery ADC: P23, 2.2 – 3.0 V operating window [Elektroda, p.kaczmarek2, post #20641851] • Deep-sleep current: ≈0.4 mA typical on BK7231N [“OpenBeken docs”].

Which GPIO handles the PIR sensor on the CB3S version of the CT61W?

Use P6 (pin 7). It mirrors ESP8266’s GPIO13 and was confirmed working in live tests [Elektroda, p.kaczmarek2, post #20482293]

How do I set up OpenBeken for motion detection?

Go to WebApp → Pin Setup. 2. Assign P6 role “dInput;1”. 3. Save & Reboot. The channel now toggles 0/1 with movement [Elektroda, pincopallino1010, post #20482307]

Why does the PIR channel stay at 1 all the time?

A top-view/bottom-view mix-up leads to choosing P9 instead of P6. Re-map to P6 and the idle state returns to 0 [Elektroda, p.kaczmarek2, post #20482293]

Do I need deep sleep when powering the sensor via USB-C?

No. Deep sleep targets battery life. Constantly powered units can run full-time without it [Elektroda, p.kaczmarek2, post #20482213]

How can I make the sensor switch a Tasmota relay over HTTP?

Add an event handler: addEventHandler OnChannelChange 1 httpget http://tasmota_IP/cm?cmnd=Power%%20TOGGLE . This fires each time Channel 1 changes [Elektroda, p.kaczmarek2, post #20482449]

Where should I paste a JSON template in OpenBeken?

Use the first (upper) text box under Config → Edit. The second field is for autoexec scripts [Elektroda, p.kaczmarek2, post #20658778]

Is there an official template for this PIR yet?

Not yet. Importer ignores PIR fields, so enter pins manually for now [Elektroda, p.kaczmarek2, post #20661910]

How do I mirror the status LED to the PIR channel?

Set P26 role “LED” and point it to the same channel as P6. LED follows channel state; use LED_n for inversion [Elektroda, p.kaczmarek2, post #20496101]

Can I adjust the sensor’s detection range or sensitivity?

No. The module only exposes a binary output; sensitivity resides in the PIR hardware, not the Wi-Fi MCU [Elektroda, p.kaczmarek2, post #20658569]

What pins are used for battery monitoring and relay?

Battery relay: P17; ADC sense: P23; voltage limits 2.2 – 3.0 V [Elektroda, p.kaczmarek2, post #20641851]

Edge case: my unit died after re-soldering; what happened?

A bad joint can break VCC or data traces—one user reported total failure after solder work [Elektroda, pincopallino1010, post #20947461] Inspect with a loupe and reflow as needed.

Quick 3-step method to find the correct GPIO on unknown Tuya gear?

Open case; note original module type. 2. Cross-reference ESP GPIO to BK7231N pin map (top vs. bottom view!). 3. Assign pins one-by-one in WebApp and watch Channel logs—takes under 5 minutes [Elektroda, p.kaczmarek2, post #20482213]
