I have a legacy home automation installation from Domintell. I am still on their old master and have no network connectivity into the system.
The system works with niko switches (momentary press) that are connected to dry contact inputs. The software allows met to link these inputs into one or more outputs or groups, create scenes. I was thinking to wire the push buttons into a KinCony B16M which is integratable with HA over mqtt. So button > mosfet > domintell dry contact. This way I could controll the inputs of the domintell system from my physical buttons and HA and HA would be able to read them. Would this work - any other suggestions (I do not have AC wiring to my wall switches, only low voltage cable to the distribution box).
