This module has a relay output, so acts like a switch. However, you can't create pulses, for example to simulate a push button. So I'd say no, you can't simulate a long press to dim a Hue bulb. However, if you have a home automation system between this module and a Hue bulb (as I do with Homeassistant) then you can create all sorts of interactions with the bulb and the switch. The possibilities are endless!
