I ordered a Zigbee usb stick right after reading the blog. It came in the mail yesterday. It took me 2 hours to install and configure zigbee2mqtt (I already had mosquitto mqtt server and home assistant installed). As I deleted my HUE and innr bulbs out the HUE app, they started showing up in the zigbee2mqtt panel, and awesomely also right in Home Assistant. I renamed the entities to what they had been before and am fully online without the hue bridge or the huge app. I deleted the hue app right after this and threw the hue bridge in the trash.
