Hi, thanks for no help at all. 
I am assuming you mean BK7231T not BK7132T!
Did you try the Python script? Also check that your soldering is not messing up your connections. I had a guy messaging me with the same problem. They then realised that two pins where shorted by his solder. He cleaned it and it worked.
I have a similar one, but haven’t flash it yet since i’m not sure about the configuration. Any guides?
Don’t see any radar device in blakadders template page
Thank you.
Blackadder has done a transplant on this device and produced the template.
See below
I have the same 3 gang switch, spent so long trying to flash it and finally succeeded using the LibreTuya python with esphome wizard.
Now I can’t seem to figure out the esphome config for these.
I see there’s the standard one on the esphome website, but don’t know how to change this config based on the LibreTuya pinouts etc. My board it s the WB3S
Would highly appreciate if someone can edit the following accordingly please

Do you know if doing it this way will allow it to be picked up by Aeotec Hub? I am about to receive the USB-to-Serial converter and will get started on my manu E27 RGB bulbs.
By the way, if anyone has experience disassembling bubls like my LSC bulb and knows how to pull the controller without having to break the connection with the power source, I would love to hear. Everything seems to be “kind of bolted” in place in the bulb (except of course, the cover)
Change the following GPIO references in your code above :
GPIO0 to D7
GPIO16 to D1
GPIO4 to D8
GPIO3 to D10
GPIO5 to D9
GPIO14 to D2
GPIO12 to D3
I tested on a 3Gang Deta and all appears ok

Hi everybody, since this discussion helped me along the way, I will just share a few lessons I’ve learned with an Arlec CCW bulb and an IR universal remote during the last few days. Both are using BK7231T chips (the bulb not anymore!):
- Since a number of people had issues with flashing, here is something that might help: Flashing in both cases for me required an additional power source; the USB serial dongle does not provide enough power!! With that it worked, without it, it worked randomly with the bulb and not at all with the IR remote. Remember to connect ground from the power supply to the chip and the dongle. Note also that reading works without an issue also without the additional power supply. Connecting the USB power cable to the IR remote and then trying to flash, did not solve the issue.
- I always had to ground CEN to bring the chip into flashing mode.
- the HA auto discovery in OpenBK did not work for me, but I managed to construct a MQTT message manually and got that registered with HA. In the end I decided to leave the IR remote completely off HA and communicate with it only through the MQTT broker. Works very well!
- Playing around with multiple images I managed to brick the bulb!!
Actually I locked myself out of the chip without a way to re-flash it and the USB dongle just would not work at all, neither reading nor writing. Well, since I kind of dislike these Beken chips anyway, I ‘just’ replaced it with an ESP12s and flashed it with ESPhome. That was a very fiddly exercise, since the pins are not really compatible. I soldered short cables and glued the ESP12s to the power supply board. Not totally elegant, but works and the chip fits quite nicely in the space of the BK7321T carrier board (WB2L)! - BTW: The serial test connector pads on the original bulb WB2L board are not accessible, since that board is soldered onto the power supply board and the pads are on the back side! There is also no CEN pad.
- Also tried using LibreTuya, but that does not support the IR functionality, yet and has a few other limitations as well.
- Also tried to dump the original firmware using bk7231tools. That generated the expected 2MB file, but when trying to use that to construct a config profile, it always complained about a missing data partition. Tried to find out how to get that, but was not able to find a description. I would have thought that bk7231tools should be self-consistent, in the sense that when reading a dump it should be complete and can then be used to generate the profile, but that does not seem to be the case. Any help would be appreciated.
- AFAIK: OpenBK does not (login) protect the config page at all, but maybe I missed something there?? Don’t like that at all.
- The universal IR remote is pretty good. It is a NEO Coolcam Tuya Smart WiFi IR Universal Smart Remote Controller from Aliexpress. Sold under a number of different names as well. Opening it, requires quite a bit of well controlled force, if you want to use the case afterwards again. However, in principle it should be possible to avoid opening it all together, since tuya-cloudcutter did work on it!

Depends on the board i guess? This one doesn’t need even 3.3v pin connected
You need to manually start mqtt discovery after configuring mqtt login.
It should show up in mqtt integration
I mostly just had to power cycle it to start flashing (not uart, just the 3.3v pin)
You can request for an authentication login, the developer welcomes any suggestion to improve it
If it gets bricked, you could still restore it back using SPI tool.
WB2L is quite common with bulbs, you could order some esp-02s that’s pin compatible
It really depends on the pcb design i guess, some had the wb2l with tx/rx pins partially exposed so you don’t need to desolder it.
I’m using batch script from here to generate the profile

are you talking about this brilliant pir sensor?
Brilliant Smart Intelliscanner Outdoor PIR Sensor - Bunnings Australia
i have the same one did you manage to flash it with tasmota?
Hi there. No, I never ended up doing it. Went with a traditional PIR sensor instead.
I do eventually want to put a smart sensor in place, as the way the switch and sensor are currently wired together isn’t conducive to installing a smart switch.
Love what you’ve done here. Does the template for the DETA double powerpoint expose the energy monitoring sensors?
I don’t think it does. I am not sure if the hardware is capable of monitoring engergy (I could be wrong). I have not tried to do this even with ESP based Deta switches. Tasmota does not show anything about Energy monitoring in its templates for Deta Switches.
I am not as familiar with the Deta switches on Tasmota. I’ve used a lot of the Makegood GPOs which do support it. I was going off the specs from the Bunnings Website so I assumed there was a sensor on one of the GPIOs.
Does anyone have a working configuration for ESPHome for PC191HA smart plug?
I flashed it to ESPhome and can update and all, but cannot get the GPIO pins to do anything =(
So far I found the following:
P6 (PWM0) - RELAY
P7 (PWM1) - CF
P8 (PWM2) - CF1
P24 (PWM4) - SEL
P26 (PWM5) - LED
P11 (TXD1) - BUTTON
P10 (RXD1) - WIFI LED
I’ve just got a window opener with a Tuya switch.
I’d like to use it without the cloud and would normally flash with Tasmota and link into HA. I think (?) this one is not compatible with Tasmota and came across this thread as a possible alternative.
Can anyone provide some confirmation before I set off on a new adventure?
Yes, that’s a beken chip so you can flash with openbeken/libretuya
I had a similar switch design like yours, swapped with an esp12.
Had to heat the chip from other side of the board to avoid melting the touchpad since it’s right next to it.
