Hi!
I’m using about four ESP32s and presence tracking (ESPresence), works ok for the most part as im using my phone which is not the greatest beacon. But my question is, does the ESP32 have a preferred direction? For example, if I limit the distance to 5 m, does that mean a 5 meter radius from the ESP32? Does it matter if I have the chips/lights side of the unit facing up, down, left, or right, etc.
Here’s what I gave
As far as I’m aware (which could be wrong), there is no specific direction on purpose.
That being said, it’s easy enough to test. Look at this example from the ESPhome website for an rssi sensor:
esp32_ble_tracker:
sensor:
- platform: ble_rssi
mac_address: AC:37:43:77:5F:4C #change this address to your beacon's mac address
name: "BLE Google Home Mini RSSI value"
Just put your beacon somewhere and rotate the esp to see what the rssi value does. The reason I’m saying that you should rotate the ESP is to avoid confounding your results by introducing the orientation of the beacon as a factor.
Please do share your findings! 
Thanks, this is a great suggestion to try! I’ll try this out and post about it.
