As mention above in multiple posts, Ecobee still doesn't expose them in their cloud API, so there is no way for a Hubitat-Ecobee cloud integration to see them.
However, there is a way to get them to work locally.
You need to set up a Home Assistent system (on a RaspPi), and using HomeKit emulation on HA import your Ecobee devices. (No Apple products or other HomeKit devices are required). All of Ecobee's devices operate locally using the HomeKit protocols. This gets all the sensors into HA, and then you use [RELEASE] Home Assistant Device Bridge (HADB) to bring the devices from HA into Hubitat.
Doing this makes the Ecobee sensors work better than they do using Ecobee's systems. There is no latency. Everything operates locally without any cloud service in the middle.
And Ecobee's sensors (both the Door/Window ones and the ones for their termostats) report better status - true motion and separate occupancy.
