Hi Yahav,
Simply put: No, we do not have the plan to implement this. Since the SpiNode is, as the name implies, a node and not a controller, it is intended to be used with a separate controller, either from VisualProductions or a third party, that sends DMX over Art-Net or sACN to be displayed on the connected SPI LED string(s).
Feel free though to elaborate on your line of thinking, and what you exactly mean by 'to activate them', so we can help you better.
Kind regards,
