Foreword: I am not familiar with the MyGekko system, I just looked at it because it annoyed me that no one here tries to seriously answer a question. If you look at this little picture about how MyGekko works:
It becomes clear that the MyGekko system is merely the control center or user interface for an arbitrarily assembled system. Apparently, various protocols and manufacturers can be mixed. Which lamps you need now therefore does not depend on the MyGekko base system, but on the type of controllers or switches you use at the respective light outlet. Whether you use, for example, a simple switch to turn a light bulb on and off, a dimmer for a resistive load, or an LED controller, you should actually clarify that in advance with the construction company. Just one more reminder from the beginning: I actually have no idea about this, so if this was total nonsense, feel free to correct me calmly.
