Homekit pairing code for Home Assitant

my app and rachio are updated. Firmware iro3-firmware-hk-5-630. App version 3.15.8

Under controller settings I don’t have a homekit option. I’m actually using the open source home assistant…not homekit but its asking for homekit pairing code to add Rachio and I’m not finding it.

Any ideas?

Thx,
Mike
