Exploring the Hama 176587 WiFi LED Filament E27: Inside Look and BK7231T Chip Dumping

This is an LED Filament bulb from Hama. I bought it because in Germany/Austria they are currently very cheap (2€) at "Media Markt".




I failed at dumping it with lightleak, so I opened the bulb (not really possible without destroying the socket).


The bulb comes with a WCL5 BK7231T Chip. After soldering the 4 pads I successfully dumped it using bk7231tool.



Channel 0 is connected to P24 (PWM4), Channel 1 is connected to P26 (PWM5)

I also added a pull request in the OpenBekenIOT webapp repository to add it to the device list: https://github.com/OpenBekenIOT/webapp/pull/43

Thanks, it's also very nice to see you adding pull request. It's always easier for me to maintain the database that way.

Btw, how does this bulb looks when on, how good the visual effect is?
