Homebridge @dan.t reworked Tonesto7's Homebridge product to follow the HubConnect API.
HubConnect makes use of the Event Socket (event stream) that all Hubitat Hubs emit constantly. HubConnect can listen to that and react to Events. Many other products can do the same thing and therefore function similarly.
@dan.t also has a version of Homebridge using MakerAPI + Eventsocket:
I read about a HomeSeer product that uses MakerAPI too.
