I've spent the last three hours or so trying to get my X10 controlled lights to smoothly dim, and am nearly going crazy(ier)! I'm using a IR7243 type device (from Lets Automate) for converting the infra red signals to X10. The codes i've download from Remote Central for the pronto work great, but i am unable to get the lights to smoothly dim. I've tried macros with and without pauses in them, and even added in extra repeating codes to the IR Code for dimming, but this has only made a slight difference. The dimming happens in four stages with a noticeable pause in between each one. It appears that it is not possible to have more than 256 burst pairs for control codes, despite the number being represented by four digit hex, so i can't extend the reoeating code any further. Pronto edit reports an error with any number after 0100 (256) Does anyone have a CCF for one of these that can smoothly dim lights? I'm at the end of my tether!
