  • [BK7231N CB2L] Antela - smart bulb E27 RGB BAW534 9W Just buy a couple of this smart bulb and teardown one to have the correct pin out and firmware :

    https://www.amazon.fr/ANTELA-Multicouleurs-27...-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1

    So simple beken7231 around a CB2L. seems like only two pin is used to SCL and SDA of the BP5758

    i have submited the update on Cloud Cutter, but if someone need to flash them any device of oem-bk7231n-light-ty-1.2.16-sdk-2.3.1-40.00 will do the trick.

    I will post some pic of the teardown later.

    Code: JSON
    Log in, to see the code


    as promise heres teardown :

    the process is destructive, so don't do it ... now that i done it you just had to flash it :)

    Thanks, but please use syntax tag to post JSON code, it will make more readable. Some photos from inside would also be nice, but they are not 100% necessary.

    So, maybe it's time to look into DDP protocol (it's already support, so xLights works for OBK) or maybe to do some kind of rainbow script or something with Hue command?

    I'm not confident with ddp protocol you want to fork wled for openbeken ?

    DDP protocol is already working. We have a very simple driver for that, but it correctly receives RGB values. There is nothing to do in that matter. I was just saying that's possible to use it if you want to create fancy light animations.

    Could you give a configuration example for DDP receipt please?

    startDriver DDP and then from xLights set channels number in packet to 3 and send something or some kind of animation.

    Tested with WLED and works fine.

    1. WLED Config

    Version v0.14.0-b1

    Added OpenBK bulb as the next hop LED after a LED string:

    2. OpenBK Config

    Build on May 9 2023 07:20:59 version 1.17.105

    Added StartDriver DDP command as a startup command
    [BK7231N CB2L] Antela - smart bulb E27 RGB BAW534 9W

    And started seing receipt of DDP packets after restart.

    Thank you for testing. Is the DDP support good enough for you, or is there something we can add or improve?

    Would it be possible to have a button start/stop reacting to DDP packets?

    That is once the driver is loaded, to allow/disallow DDP reaction.

    Ideally a MQTT command also for the same.

    DDP support opens up a new concept of holiday decoration.

    Now you can replace bulbs around your house with DDP enabled WiFi Smart RGB Bulbs and run some nice animations around your house.

    There is a simple httpButtons driver, maybe you could use that?
    Sample autoexec.bat:
    Code: text Expand Select all Copy to clipboard
    
startDriver httpButtons
setButtonEnabled 0 1
setButtonLabel 0 "Turn off after 10 seconds"
setButtonCommand 0 "addRepeatingEvent 10 1 Power Off"

    you can modify it to make a command that runs stopDriver or anything...

    Also, why do you want to allow/disallow DDP reaction instead of unloading/loading the driver?

    BTW, how to do I control the WW/CW LEDs of a RGB-WW/CW Bulb.

    There are no buttons on the GUI.

    I have defined the following PWMs:

    Pin 6 PWM 3
    Pin 7 PWM 2
    Pin 8 PWM 1

    Pin 24 PWM 4
    Pin 26 PWM 5

    I presume the PWM 4 & 5 are for WW/CW LEDs.

    Can the unloading/loading be done on the fly without restarting the device?

    Well, you must reboot to get autoexec.bat executed. If you don't want to reboot, then type those commands in console and you will get immediate effect.

    You can do stopDriver/startDriver without reboot.

    Is your bulb RGBCW? 5 PWMs? Then you should have both temperature and color controls on WWW panel. Do you? If not, please post a screenshot.

    Can you explain the reason for following response please?

    Hmm you are correct, there was two potential mistakes in the code. The Dimmer command for LED was always returning error because it was not updated with commands system revamp. It should be fixed now, please update and recheck.

    Following error is still there:

    However the http command get 200 OK now

    I tried the httpButtons but was unsuccessful.

    Tried with autoexec.bat which included startDriver httpButtons command as well.

    Got the errors.

    Then loaded driver using Startup command text
    (driver gets loaded successfully)

    Code: text Expand Select all Copy to clipboard
    3 drivers active (HTTPButtons,DDP,SSDP), total 34

    and then added autoexec.bat as follows

    [BK7231N CB2L] Antela - smart bulb E27 RGB BAW534 9W

    Still I am getting the error:

    Let me check on that device:
    [BK7231N CB2L] Antela - smart bulb E27 RGB BAW534 9W
    Let me save that:
    [BK7231N CB2L] Antela - smart bulb E27 RGB BAW534 9W
    And reboot:
    [BK7231N CB2L] Antela - smart bulb E27 RGB BAW534 9W
    Hmm:
    [BK7231N CB2L] Antela - smart bulb E27 RGB BAW534 9W

    You might be getting errors because autoexec.bat may get run first before httpButtons is started. Please start httpButtons first before using them.

    You might be also getting errors because of encoding/UTF problems on some browsers. Please try to retype the script by hand into the field. We've had such a problem report once, but we are unable to reproduce it.

    Also post your complete autoexec.bat, I will double check later.

    After I typed the contents manually on a notepad and then cut and pasted in to browser it worked (I am still puzzled as to why when I copied your script on to a notepad and then cut and pasted again in browser it did not work. Notepad++ does not do different UTF encoding at different times, it should all be same).

    I'm trying to make what >>20575084 described; it would be awesome if the ddp driver in a lamp (maybe more than one in the future) could be enabled and disabled on the fly from ha.
    The esphome equivalent is light effects.

    Is there a way to do that without using a custom button and control it from ha?
    Maybe a mqtt command like cmnd/OBK_DEV_NAME/COMMAND_TEXT (if I manage to get it to work)?
    edit: this did the job:
    Code: text Expand Select all Copy to clipboard
    
topic: cmnd/<device name>startDriver
payload: DDP


    Now to get it working from ha!
