Smart thermostat with access to AUX Heat

Hardware
1

Anyone know of a thermostat that plays nicely with HA and gives access to AUX Heat? I need to be able to pick my primary or secondary heat source.

I currently have an ecobee, but when connected via Homekit, control options seem pretty limited.

Any ideas?
