# ESP-32-BLE-Scanner
for Home Assistant. [See thread at Home Assistant Board.](https://community.home-assistant.io/t/esp-32-ble-scanner-a-room-presence-detection-solution/315205)

### What does this program do?
This is basicly a room presence detector. Use it with Home Assistant to trigger automations when you enter a room, disarm your alarm etc. It reports the presence of known bluetooth (Beacon) devices and reports it (via MQTT) to Home Assistant. I designed the program to work together with the HA Android App (IOS not tested yet).

### Please keep in mind
This is my first project on github, I am programming in my free time during my 9 to 5 job and I am not a professional programmer. I will try to support and fix errors as good and as fast as I can.

### Features
- Web UI to set everything up
- MQTT Client to report state to Home Assistant
- BLE Beacon Scanner for 3 different devices (more to come in the future)
- Works fine with Android Home Assistant App
- Easy Integration into Home Assistant
- Raw distance calculation

### Roadmap
- [X] provide bin for making first flash easier via ESP flash tool
- [X] improve MQTT and MQTT response
- [X] online status for the ESP32
- [ ] make update via Web ui possible(binary upload)
- [ ] better distance calculation
- [ ] more network settings (fixed ip etc.)
- [ ] add bluetooth scanner settings
- [ ] add support for more bluetooth devices like smartwatches etc.
- [ ] add support for more devices being saved

1. The ESP32 should start its own AP - look for a Wifi named "ESP32-BLE-Scanner" / If you changed settings.json you can jump to 5.
2. Connect to the Wifi (it should not have a password)
3. Go to http://192.168.4.1 Setup and change your Wifi and MQTT settings

5. Wait for the ESP32 to restart and check for the IP adress with an scan tool or check the serial connection for the device ip
6. Connect to the Scanner and fill your Bluetooth details under devices. (See Setup HA APP for how to get your UUID)
