@p.kaczmarek2 Let me make a small correction to your project.

@azavialov I am not at home right now and I can't check your fix, but at least one of your setting seems to be duplicated:

@botioni did you enable "force show rgbcw controller" flag?

Hi, I'm running firmware 1.14.93.
This plug is using a BL0937.
It is constantly reporting pulses of 1.2W even when it's in the off state.

Hi, looking at scripting example 3,
Could I do something like this? Select different brightness command for each hold button action?

Code: text Expand Select all Copy to clipboard
addEventHandler OnHold 8 DGR_SendBrightness lamps 90 DGR_SendBrightness lamps 50 DGR_SendBrightness lamps 10

Is it possible to store previous variable then just select the next action?

No, you’ll need to use serial method to perform that.
This instruction is taken from libretuya’s developer. I haven’t try this yet though


Do this:
- take the full dump (2 MiB / 2,097,152 bytes)
- cut the middle of it - starting at 0x11000, all the way to i.e. 0x132000 (so it results in a bit more than 1 MiB)
- flash it to offset 0x11000

^ this method will work for both T and N. 
Flashing to 0x0 on T is impossible. On N it's unnecessary and causes flash wear-out. So don't ever flash to 0x0 at all.

Can I request an additional channel type? I would like to see an OffLowHigh channel type with the heading "Power indicator LED:." I've been testing with a dimmer switch that has a power indicator LED that is controlled by the TuyaMCU. The three functions are Off (0), Low (1), High (2). Currently, I have been using channel type LowMidHigh, which works, but the heading reads "Select speed:," and the three options are Low, Mid, High. I edited the webpage HTML to give an example:

Hello dear,

I have two smart bays for which I cannot install the software for using them outside the cloud,
one GOSUND SP1-C, the other AWP08L,
After disassembling them in AWP08L, I found the BK7231T chip and this seems to be supported by software prepared by @ p.kaczmarek2,
in the second there is a module that I cannot identify
I am asking for information and help,
Is it possible to reprogram AWP08L without connecting via RSp-TTL, and whether the second socket also gives a similar possibility
Below are photos of these devices, if there is a need to do a flash dump, I will be able to do it with a little help
Thank you in advance for any help

greetings

I can add it for you, but what about simply adding an option to set any user-defined heading for a given channel? Would that work good for you?

Was the plug calibrated?

I can add an options to always report 0 power consumption if relay is in off state, if that's needed.

Maybe we could try catching both first press of button and setting a variable to 0 there, then catch each hold and increase variable on each hold. But that would send a lot of packets. I will try it for you, wait...
but what are you trying to achieve? Why not simply two buttons, one for brightness up and second for down?

Indeed, that's a better solution for wall switch with more than 2 buttons.
How does that work? Does it mean the longer I hold, the higher the variable increases,
i) It sends brightness variable after I release button or
ii) It keeps sending the brightness variable as I keep holding the button

What I was trying to achieve was for 1 button wall switch.
My nodered flows is this:
Click - toggle lights on/off
Double Click - toggle between cold & warm light
Hold - Cycle between 20%, 50%, 90% brightness <-- using hold action to just cycle different brightness. using input helper,the flow retains the last brightness toggled, so if it was 90%, another hold action cycles/reset back to 20%. Next hold is 50% and so forth.

@_leming_

For the one with bk7231t, you could try tuyacloudcutter to flash via ota

As for the other unidentified module, it could be CB2L (bk7231n). Could you try opening the metal case to be sure?

It will require again firmware update (but maybe wait one day, because @btsimonh is investigating something in LFS update), but it works for me, tested right now, although you might change the added value from 2 to larger because its slow:

Code: text Expand Select all Copy to clipboard
// Button OnHoldStart and OnHold demo // Requires a button on pin 20 // Channel 10 is used as variable // When button hold start happens, channel 10 is set 0 // When a button is held, the value is added to channel 10 repeatedly. // Also, when adding, the channel 10 is used as a brightness for Tasmota Devices Group startDriver DGR // generate repeat after 100 ms - yes, unit here is times 100ms // so 1 means every 100ms // 2 means every 200ms setButtonHoldRepeat 1 // when Hold starts, zero the variable addEventHandler OnHoldStart 20 SetChannel 10 0 // when Hold repeats, add a 10 value as a step // AddChannelSyntax: channelindex delta minValue maxValue // the 0 255 is needed so we clamp the value to 255 addEventHandler OnHold 20 backlog AddChannel 10 2 0 255; DGR_SendBrightness roomLEDstrips $CH10

also it's possible that doing startDriver DGR in autoexec.bat might be too quick, if so, we will add a delay...

I have a lamp - https://www.aliexpress.com/item/1005004319893210.html
BL602c20 has inside, I flashed OpenBL602_1.14.90, the controller started, but the control of the lamps turned out to be through UCS1912S led driver chip. And I don't know what to do next.
I have already identified all GPIOs.

@ferbulous it is possible to use both positive and negative values for arguments.
For the floating point or integer arguments, the math expression syntax also is supported (but don't update yet, it's early stage).
So the following will work:
Code: text Expand Select all Copy to clipboard
// sets channel 1 to channel 2 value + 2 setChannel 1 2+$CH2

Code: text Expand Select all Copy to clipboard
// sets channel 1 to channel 2 value * 2 setChannel 1 2*$CH2

Code: text Expand Select all Copy to clipboard
// sets channel 1 to the logical value of MQTTOn setChannel 1 MQTTOn

@botioni the tutorial for compiling is here:
https://www.elektroda.com/rtvforum/topic3850712.html
but for OBK there is one step more - read our readme - just checkout APP repository into the SDK repository for chosen platform

@Sergio127 wow, that's a good job, you even drawn a schematic! This deserves a separate topic. Can you please post it here:
https://www.elektroda.com/rtvforum/topic3912748.html#google_vignette but also include screenshots from the seller link (because links tends to expire) so we can add it to our online devices database?
https://openbekeniot.github.io/webapp/devicesList.html
Regarding your question: here is a datasheet of UCS1912S :

As you may see, it will require a simple driver written in C code. I can write one for you, but would you be able to test it somehow? Do you have C knowledge to help?

Hi,

a while ago, I purchased these fairy lights:

I successfully flashed them with OpenBeken, but I had no luck configuring them so far and was hoping I could get some help here

My device looks pretty similar to that one here: https://www.elektroda.com/rtvforum/viewtopic.php?p=19932845#19932845
But instead of having 3 outputs for R G B mine only has one labeled LED. I think because they are individually addressable LEDs.

I tried tracing the connection labeled LED with a multimeter and marked the pin on the WB8 chip on the attached picture.

Here are some pictures:

Please let me know if I can provide any additional information or pictures that could help!

@yonnit I can get a driver for you for that device, but are you able to determine what kind of LEDs are used there, or at least tell us if they were able to have different colors (each LED different color) with Tuya firmware?
I'd suspect they are ws2812b.

@p.kaczmarek2 hi, there's this odd thing happening when I'm choosing colors, the brightness keep changing.
As for the warm & cold lights, changing the brightness also changes the rgb bulb color icon (not actual warm & cold lights) for some reason.
Anything else I need to enable in the general settings to fix this?

Btw, I just reset one of my switch and 1 bulb and both are getting the same mac id:
Device MAC: C8:47:8C:00:00:00
I tried changing the switch mac id by grabbing random mac address from mac generator but now it's no longer connecting to wifi.

As for colors, you can open a new issue on git. Was it always like it?

As per MAC, there is already a tool for that. Go to Web App, go to Flash tab, and press "Restore RF Config". It will create a correct RF partition if you have lost your one. It should work on both T and N.

That option will restore MAC partition and also add a random mac to it.

Warning: if you don't have access to easy way of emergence flashing your device, you might want to wait a day or two before doing that That option was added yesterday and is in testing phase. Still, I tested that and it worked for me well.

For my switch, I've tried flashing openbk again using serial method and did 7x power cycle. I can see the AP, but I just can't connect to it

You can do this anytime you want. No need to do resets. Just remember it will change your MAC address to something random.

Regarding AP issue - you might have gotten unlucky and gotten the build with a temporary issue which is resolved. Try latest build.

BTW: We are migrating from daily Releases to doing Release every week or two with a stable tested features. There will be also a daily alpha builds, but they might be unstable. More details coming soon.

Second news: I wrote a simple SPI flasher for BK, right now just with hardcoded parms, more coming soon...
https://github.com/openshwprojects/BK7231_SPI_Flasher
This tool is able to bring back the bricked BK chips back to live.
