Ok am I missing something? I went into the Ecobee system menu and disconnected it from it's existing home kit integration with Home Assistant. Also in home assistant I disconnected it from there also. Both HA and the thermostat showed the connection was disconnected.
Then I went into the HomeKit app in the Hubitat C-8 and saw the name of my thermostat "Home" as a discovered device. On the Ecobee I went into the connect to Homekit and got the numeric code for connecting.
In the Hubitat I clicked on the pair button and it promoted for the code. I put in the code and it said pairing successful. At that time the Ecobee went back to it home screen and on the setting screen it said it was paired.
But no devices show up and this is displayed in the status of the pairing:
Any ideas? I have tried the un-pair and re-pair many times waiting as much as 30 minutes between actions.
