BEKEN iLedBlub

These are LED lamps E27 ~7W with Bluetooth BLE, in variants of RGB color, and without.

Manufacturer/distributor Hama/Xavax.

Product number 00111973 (case marking: 001119730001).

Currently (2018-01-09) sold at http://pollin.de for 4,95 Euro ([1] , [2]).

And, since these are called iLedBlub (sic!), I chose to use the same name for this page.

I managed to figure these access details out relatively easily (~2 hours), without actually doing Bluetooth sniffing. If someone has a Bluetooth sniffing environment easily available, then it would be useful to gather potentially remaining additional commands sent by the XAVAX II app.

I'm currently working on a FHEM module, taking 74_XiaomiFlowerSens.pm as a reference. I will thus possibly use gattool interfacing (or perhaps interfacing to MQTT, but this would require an extra MQTT provider component), and Color.pm (FHEM's color picker wheel).
