I’m trying to combine Android Beacon Simulator, ESPHome and ble_presence for presence detection.
The Android Beacon Simulator emits an IBeacon with a UUID. I’m trying to capture that UUID with esphome as follows:
binary_sensor:
- platform: ble_presence
service_uuid: '50B04BBB-7B26-06AC-7441-92140A6A9E2b'
name: "Ronald BLE GSM"
If I turn on very_verbose logging, I see the UUID passing by but it is not yet recognized by ESPHome.https://github.com/esphome/issues/issues/1486
Is there anybody with some C++ knowledge and BLE knowledge who can chip in?

Bingo:
[00:24:29][D][ble_adv:404]: New BLE device
[00:24:29][D][ble_adv:415]: Advertised manufacturer data:
[00:24:29][D][ble_adv:417]: - 02.15.2B.9E.6A.0A.14.92.41.74.AC.06.26.7B.BB.4B.B0.50.00.00.00.00.BF (23)
This is broadcasted every 15sec or so. I hope I can finally make my presence detection working!

You can share the code in ESP32. I’m not wise how to set it. Mac address is tracked phone? Service uuid id is uuid what creates Beacon Simulator? If I set up scan esp32 ble tracker won’t find mac phone.Thank you

I tried the nrfConnect app and it works well for rssi ESP32, but I didn’t find how to let it run in the background so it’s not very useful.

Are you able to share your esphome.yaml file showing how you used
I can’t figure out how to get it working.

I think this works
esp32_ble_tracker:
on_ble_advertise:
- then:
- lambda: |-
bool redmi_note_9_pro_status = false;
for (auto data : x.get_manufacturer_datas()) {
if (strcmp(hexencode(data.data).c_str(), "02.15.49.01.F3.6B.E9.1A.44.B7.B3.62.FF.2E.B6.43.05.04.00.00.00.00.BF (23)") == 0) {
ESP_LOGD("ble_adv", "redmi_note_9_pro found");
redmi_note_9_pro_status = true;
}
ESP_LOGD("ble_adv", " - %s", hexencode(data.data).c_str());
}
id(redmi_note_9_pro).publish_state(redmi_note_9_pro_status);
binary_sensor:
- platform: template
device_class: presence
name: "Redmi Note 9 Pro BLE presence"
id: redmi_note_9_pro
filters:
- delayed_off: 3s
whit this code (thank @rdehuyss ) I can track my android phone with the app beacon simulator

That’s better:
binary_sensor:
- platform: template
device_class: presence
name: "Lenovo P2 BLE"
id: Lenovo_P2
script:
- id: ble_off_script
mode: restart
then:
- binary_sensor.template.publish:
id: Lenovo_P2
state: true
- delay: 60s
- binary_sensor.template.publish:
id: Lenovo_P2
state: false
esp32_ble_tracker:
on_ble_advertise:
- then:
- lambda: |-
for (auto data : x.get_manufacturer_datas()) {
if (strcmp(hexencode(data.data).c_str(), "02.15.1A.D3.91.06.87.AC.4D.35.A3.60.5A.96.49.FC.E7.2E.00.00.00.00.BF (23)") == 0) {
ESP_LOGD("ble_adv", "Lenovo P2 found");
id(ble_off_script).execute();
}
else
{
ESP_LOGD("ble_adv", " - %s", hexencode(data.data).c_str());
}
}

thanks, and thank you to the original poster for this. I just got it working myself. I find the range is a bit limited to usefull for me… It is really only for one room around 5-6 m away from the ESP32 device.
how would this look for two devices?
This part I have figured out ofc.
- id: ble_off_script_phone1
mode: restart
then:
- binary_sensor.template.publish:
id: Lenovo_P2
state: true
- delay: 60s
- binary_sensor.template.publish:
id: Lenovo_P2
state: false
- id: ble_off_script_phone2
mode: restart
then:
- binary_sensor.template.publish:
id: Lenovo_P3
state: true
- delay: 60s
- binary_sensor.template.publish:
id: Lenovo_P3
state: false
- id: etc
But what part needs to be copied in the “on_ble_advertise:” part?

Try this
esp32_ble_tracker:
on_ble_advertise:
- then:
- lambda: |-
for (auto data : x.get_manufacturer_datas()) {
if (strcmp(hexencode(data.data).c_str(), "02.15.1A.D3.91.06.87.AC.4D.35.A3.60.5A.96.49.FC.E7.2E.00.00.00.00.BF (23)") == 0)
{
ESP_LOGD("ble_adv", "Lenovo P2 found");
id(ble_off_script_phone1).execute();
}
else if (strcmp(hexencode(data.data).c_str(), "02.15.1A.D3.91.06.87.AC.4D.35.A3.60.5A.96.49.FC.E7.2E.00.00.00.00.BF (23)") == 0)
{
ESP_LOGD("ble_adv", "Lenovo P3 found");
id(ble_off_script_phone2).execute();
}
else
{
ESP_LOGD("ble_adv", " - %s", hexencode(data.data).c_str());
}
}

You may also need to increase the delay. I stopped at 120s for now.

If you go with the if, else if, else solution, I get a multiline warning.
Compiling /data/wemos_d1_mini_1/.pioenvs/wemos_d1_mini_1/src/main.cpp.o
src/main.cpp:331:3: warning: multi-line comment [-Wcomment]
// - lambda: !lambda "for (auto data : x.get_manufacturer_datas()) \n{\n if (strcmp(hexencode(data.data).c_str(),\
^
but the code works anyway. So I dont bother too much about it.
PS, what is the range you guys get with this BLE solution?

Somewhere 5 meters. You can increase the power in Android Beacon Simulator, but that’s enough for me.

Is there any posibility to send to HA the RSSI power by a sensor addiotionally to send Home/Not Home binary sensor?.
I want to mix this functionnality with Room Assistant, but I don’t know how to do it…
Thanks,
Jose

Thank you to everyone on this thread. I was finally able to get an RSSI sensor set up using Beacon Simulator. Until I came across this I couldn’t figure out why I could never find the beacon via UUID.
For anyone else that is trying to do the same, here’s the relevant yaml I used to get it to work, where C3:D1:26:E2:7E:B1:43:EF:AE:59:82:48:D5:33:17:1C is the UUID entered in the Beacon Simulator app:
esp32_ble_tracker:
on_ble_advertise:
- then:
- lambda: |-
if(x.get_ibeacon().has_value()) {
auto ibeacon = x.get_ibeacon().value();
if(strcmp(ibeacon.get_uuid().to_string().c_str(), "C3:D1:26:E2:7E:B1:43:EF:AE:59:82:48:D5:33:17:1C") == 0) {
id(my_rssi).publish_state(x.get_rssi());
}
}
sensor:
- platform: template
id: my_rssi
name: "$friendlyname My RSSI"
icon: "mdi:mdi-signal-distance-variant"
update_interval: never
unit_of_measurement: "dBm"
filters:
- sliding_window_moving_average:
window_size: 5
send_every: 1
