Create my own BLE motion sensor

[jacauc (Jacques)]

I would like to utilize esphome on an ESP32 to create a motion sensor that sends it’s values via BLE to HA bluetooth instead of using wifi.

Ultimately I’m looking to run the ESP32 with a battery and only wake it when motion is detected, send the motion to Bluetooth>HA and then sleep again. No other wifi or battery draining services should be running

I played around a bit, but cannot seem to get it going. Any guidance would be appreciated!

Example on setting up esp32 as BLE server?

There are 2 ways - at least that I know about - how you can communicate: Advertisements - connection-less, max 31 bytes of payload Client-server - requires connection, up to 512 bytes. I tried both of them and working on a blog post with more details, but in I’ll try to cover them here briefly. One thing I’d note - I’d agree with the above comment is that communicating data directly to HA is somewhat cumbersome. It’s much more convenient to use another ESP32 that will bridge BLE to HA. In m…
