Ecobee Premium is not seeming to auto-detect with Apple Homekit

Oh, I am sure I am not the only one who wishes ill on whoever at Ecobee decided to discontinue the API in March of 2024.

I added “zeroconf:” in my configuration.yaml and I know that my new HA VM is on the exact same subnet as the Ecobee thermostat but for some reason, it is not autodetecting. Am I doing something wrong in that configuration.yaml file? It detects my Rachio irrigation controller and all my Kasa/TP-Link surge protectors even though I used their integrations. I just do not see the thermostat and I have rebooted plenty of times in the last couple of days.

# Loads default set of integrations. Do not remove.

# Load frontend themes from the themes folder
