Describe the bug

While calibrating (calibration 1: global, second step, attenuation) I noticed that as I lower the attenuation value, the distance decreases. However, the wiki is clear regarding that: lowering the attenuation should increase the distance.

See attached screenshots below (e.g. looking at RSSI actual -70 between the two).

I was wondering if sometime this can actually be the case or if something is clearly wrong with my config, which I didn't change but for the calibration part.

Setup:

  • esp32 are these
  • the beacon is the one from the HA companion on my Pixel 3 watch.
  • the watch is sitting at ~3.5 meters from the receiver, line of sight.

this is because your reference power is set too low, it should be never be lower than RSSI Actual
