What you might be able to do is hook a pot up to your LED driver, the one I use for the living room has 0-10V (=pot) or PWM input for dimming, no inline module required. I drive mine with a Zigbee ...

The cost for an LED replacement like the one seen disassembled ... The one we find most interesting is a PWM based dimming hack he pulled off with an Arduino board and a FET.

[Leo] looked at the WS2811 LED driver, but found that the low drive current and the 8-bit PWM output failed to tick ... He did something similar when he managed to dim a non-dimmable LED fixture.

Sunpower’s DAP-04 DALI to PWM converter is designed to provide DALI control in LED lighting applications. The DAP-04 has a DALI input that can accept data from a remote IEC62386-101, 102 or 207 ...
