I have purchased this iBeacon https://www.feasycom.com/fsc-bp108b and it connected fine to my HA. However, I am not able to do any automation as the offered states do not correspond to what is shown in the logs. So no automations are started with either enter zone or leave zone. The logs show detected away and detected at home, and neither triggers entering or leaving a zone.
Try a zone or state trigger instead of a device trigger.
