I never got home assistant working, so got myself Hubitat hub (C7), which supports both Zigbee and Zwave radios and now exports them as HomeKit devices. So cheap sensors easy to pickup now are exposed to my HomeKit setup. That Hue motion sensor now directly connected to the the Hubitat and Hue bridge is somewhere in the box.
But at the time of setup, I was surprised that Hue Bridge didn't have an account. Didn't think about this until recent articles saying that account is now going to be mandatory.
