Started the setup but my HA Yellow does not have bluetooth. Followed your instructions up until see the captive portal guide linked below. - I could not find a link. Did google and found the generic ESPHome page and got the localdeck on my network and automatically detected in HomeAssistant. I have the device and the 50 entities.
At 4:22 in the Quickstart video - head over to references - what is that? I can’t say I have encountered references before.
