BLE Beacon - issues with Pixel 3

i try, but under settings in the watch HA app, i only found battery sensors … no other to active

you need to be on the beta version of the app to see the sensors labeled as “beta”

sry for asking, but how do i get the beta version of the app?
i searched in the settings from HA on my smartphone, but nothing.

its not listed in the app but we have it on Github and the companion app documentation that I linked to earlier.

works, thank you
