Hi I would like to contribute to this repo and collaborate with you to introduce the capability to add the door and window smartsensors into Ecobee integration directly. Since, these are only occupancy (remote) sensors and not thermostats, currently the ecobee integration does not recognize them as binary sensors. In my understanding this is due to the way the ecobee API calls are made in the get_remote_sensors() function i.e. self.thermostats[index]["remoteSensors"]. Please let me know if this something you have on your to do list already or you'd like to discuss more on this to get the ball rolling on this.
