Ultegra Di2 and Varia UT-800 light control

I'm working on my first app and have been thinking about light control. I have understood that the Edge 530 and UT-800 can work OOTB so that the intensity is proportionate to the speed but I guess I'll have to implement it myself if I want it since it's a separate app.

Does anyone know if the Ultegra Di2 top buttons can be customized for "hold"? I saw it mentioned for Dura-ace but haven't seen it mentioned for Ultegra. I would like to use the top buttons like "single press = next/previous view" but as "hold = light level up/down". Technically I could simulate it with a timer detecting a double click, right? Has anyone else done light control like this in their app?

Thanks in advance,

  • Hi Nik!

    I dug a bit into di2 control, but as far as I see it there is no way to have custom access to the di2 buttons through the SDK. At least not yet.
    I would also want some custom thing like jump to first screen on hold, but I cannot do it.
