How to flash LSC Smart Ceiling Lamp model 3206306 featuring WS2812 RGB LED ring? How to configure WS2812/SM16703 LEDs to work along with PWM CW LED strip? How to run it cloudfree and pair with Home Assistant? Here's a short firmware change guide for one such product. We'll use a simple USB to UART converter to flash LSC/Action lamp with our esphome/tasmota style firmware, OpenBK.

Here's full video:

Here's the used script:
Code: text Expand Select all Copy to clipboard

That's how you can flash your LSC Smart Ceiling lamp and run it cloudfree, with Home Assistant. The same approach can be used for RGB-only lamps, then you just configure RGB WS2812 LEDs and skip CW step. This way you can actually drive any WS2812 strip, just connect it to P16 (hardware SPI output) of BK7231 and it will work with shown script.

Let us know if you've flashed any devices this way! We can help with programming process and guide you step by step. Thank you for watching, see you!

A pleasant effect is generated by this lamp. How does it look on the wall the shadows/transitions between colours are sharp or smooth?

Hello the light does not restore previous state in case lose of power like tasmota lights do (on/off state, set color, set white color). Is there any way to configure this? It is also a must have when my WiFi or Loxone fails for some reason.

@TechEkspert the top dome diffuses the lights nicely, the RGB is not very bright but still effect is nice. I can try to make a video of effect soon.
@cijoml well, do you have this option enabled in flags?

Thank you manipulating flags made it to work however.
I try manipulate via HTTP commands from Loxone and:
http://192.168.5.128/cm?cmnd=color%20255,255,255,255,0
This in original Tasmota deactivate RGB strip and activate Cool strip, however OB change color at RGB strip
Same apply for Warm color command
http://192.168.5.128/cm?cmnd=color%20255,255,255,0,255
These are commands I use in Loxone for several Tasmota bulbs just copy paste
Is there any flag to active same behavior?

Also dimming does not work via this command for example dimmed warm light
http://192.168.5.128/cm?cmnd=color%2025,25,25,0,51

Are you really sure that it is:
Code: text Expand Select all Copy to clipboard
255,255,255,255,0

This looks like setting all channels except last (Warm White) to 255.
I'd rather expect that to enable Cool strip, you just do:
Code: text Expand Select all Copy to clipboard
0,0,0,255,0

Can you double check? I can adjust the color command if needed, but I am not sure about this yet.

Yes it works like this at least from Tasmota v.11.x I started with. Now I run Tasmota 14.5
I use these bulbs:
https://www.aliexpress.com/item/1005007226730234.html

I created few colors so it works like:
green 17,255,0,0,0
blue 15,0,255,0,0
red 255,0,0,0,0

What happens in Tasmota when you do:
Code: text Expand Select all Copy to clipboard
0,0,0,255,0

instead of
Code: text Expand Select all Copy to clipboard
255,255,255,255,0

I think I can change OBK behaviour to match Tasmota better, just like you requested, but I'm curious, does that mean that Tasmota ignores RGB values when you give also CW values in "color"?
?
Can you check and tell me?

Are you saying that both those commands:
Code: text Expand Select all Copy to clipboard
color%200,0,0,255,0

Code: text Expand Select all Copy to clipboard
color%20255,255,255,255,0

NOTE: %20 is an escape code for space.

are changing color to Cool White?

BTW this is a very dangerous and security flaw passing PASSWORD to the log and even worse into INFO log level:

Info:MAIN:Time 5, idle 186369/s, free 78256, MQTT 0(0), bWifi 0, secondsWithNoPing -1, socks 2/38
Info:MAIN:Registered for wifi changes
Info:MAIN:Connecting to SSID [CIJOML-2-IoT]
Info:MAIN:ssid:CIJOML-2-IoT key:MYREALPASSWORD
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

WTF?! Please fix this bug!

Added after 1 [hours] 18 [minutes]:

>>21451077 yes I know that %20 is space which is according to Tasmota documentation

I'm not sure what can it change when the firmware is open source and anyone can read flash/OTA any build, but here it is:
https://github.com/openshwprojects/OpenBK7231...mmit/9b9f6359d43a62b0026af8d88726dd12a911f0cc

So what about my initial question? What is the difference between:
Code: text Expand Select all Copy to clipboard
255,255,255,255,0

and
Code: text Expand Select all Copy to clipboard
0,0,0,255,0

?
Do those two values set the same color (cool white) in Tasmota?

I still cannot get the light switch on/off from Loxone. If I call same url from Firefox it switch on/off, if I send same command (which works with tasmota lights) from loxone, OBK send 200 OK, but light remain dark

What kind of reply do you get?

Let me test... on my device:

I send:
Code: text Expand Select all Copy to clipboard
http://192.168.0.212/cm?cmnd=Power%20On

Now it's on.
I can also turn it off:

Maybe you have different config than me? What is your config?

or wait, are you saying it works from firefox but does not work from loxone? Can you provide 1:1 full command that is sent from Loxone? Maybe with HTTP header?

@p.kaczmarek2 well I made experiments and used headers generated by Firefox (F12 function) and inserted it as a header during request. Than light work. So I suppose there is problem with receiving request from nonstandard platforms

Can you please give me here both headers (working and not) in text format, in code block, so I can do tests on my side?

How can I investigate HTTP headers in OBK? I tried setup HTTP logging but no headers are shown. Both Loxone server and the light are in the same network so I can catch only my browser's communication.

Topic summary

The discussion revolves around flashing the LSC Smart Ceiling Lamp model 3206306, which features WS2812 RGB LEDs, and configuring it to work with PWM CW LED strips. Users share experiences with the lamp's light diffusion and color transitions, as well as issues related to power loss and state restoration. The conversation includes technical details on manipulating flags for color commands via HTTP, comparing behaviors between OpenBeken and Tasmota firmware, and addressing security concerns regarding password logging. Users confirm that specific commands produce the same output for cool white light, and there is a focus on achieving desired functionality with Home Assistant integration.
