Guys,Seems that the LSC Smart Connect from Action in the Netherlands is roughly the same. I do have that issue that only 2 of the 4 filaments turn on. So maybe there is a second pin we need to enable.Device info:LSC Smart Connect 30016867 watt coming with 2.9.27 firmware, ran tuya cloudcutter without any issues.For now Have not crushed / opened device and it is already running OpenBeken, so any tips are welcome.Niels

Have you tried GPIO doctor from the Web App?

Figured them out based on the JSON code.For this one, the settings are:P24, PWM 0P26, PWM 1Now the controls are perfect.Niels

So they have Cool and Warm mode? Or how it works? It seems that our teardowns list needs an update for this device..

Do them bulbs come with just audio? Or both audio and video?

I successfully recovered the firmware v.2.9.15 as backup. Feel free to ask if there is anything more of interest.

I fear for this specimen, I need a custom socket now .

P26 PWM on channel 0 fixed bulb control
Post #4 20527050 06 Apr 2023 01:46

Got it working! The configuration was just P26 PWM for Channel 0.
Next thing is to control it via https://nymea.io/.

I tried to make a pull request for the device list, but messed that up.
https://github.com/OpenBekenIOT/webapp/pull/52
the relevant commit is just
https://github.com/OpenBekenIOT/webapp/pull/5...mits/99d555e215f1909adaf8c2a963487f3fe226d92c
It is already too late to fix that right now. Sorry for that.

anyways: Thank you for this awesome piece of firmware!

Here's your JSON:

I will just add it manually, thanks.

Guys,

Device info:
LSC Smart Connect 3001686
7 watt coming with 2.9.27 firmware, ran tuya cloudcutter without any issues.

For now

Have not crushed / opened device and it is already running OpenBeken, so any tips are welcome.

Figured them out based on the JSON code.

For this one, the settings are:
P24, PWM 0
P26, PWM 1
Now the controls are perfect.

It seems that our teardowns list needs an update for this device..

Topic summary

✨ Discussion about identifying and configuring a LEDVANCE SmartPlus AC32956 filament classic E27 bulb based on BK7231T and WBLC5 hardware. The device was successfully cloudcuttered, firmware v2.9.15 was backed up, and the working OpenBeken configuration was determined to be PWM on GPIO26 for channel 0. A JSON device entry was prepared and later manually added to the device list. Another similar LSC Smart Connect filament bulb was also discussed, where only part of the filaments lit until the correct pin mapping was found: GPIO24 as PWM0 and GPIO26 as PWM1. Suggestions included using GPIO Doctor, enabling SSDP for Windows discovery, and integrating the bulb with MQTT/open-source home automation platforms such as Nymea.
