## Description

desertcart.com: Blue Charm Beacons - Bluetooth BLE iBeacon (BC021-MultiBeacon) with Movement Sensor - Long Range BLE 5.0 : Electronics

Review: Robust and reliable ESP32 BLE iBeacon tracking in Home Assistant - Absolutely love this little guy on my keyring. Works as a super reliable and almost zero latency presence detector for Home Assistant automations when I arrive and leave home. I configured my ESP32 AIR-1 and MSR-1 air quality sensor and mm wave radar devices as BLE proxies and they do a great job of picking up the advertisements. Absolutely wonderful to finally have something so reliable and instant to trigger automations when I leave and arrive my NYC apartment. Absolutely zero false triggers/flapping in my year of using it. It's super configurable with the phone app (you can pair right after you turn on the device to set up). It's definitely worth it to take the time to read the documentation--there is even a button functionality you can configure for an additional remote trigger after you arrive home. Highly recommended!
Review: Recommended! - I used 3 of these to develop a system to track my cars in the garage. They worked extremely well. Documentation and the corresponding app were excellent. Recommended

## Questions & Answers

**Q: Can i use this to broadcast Droid [from WDW galaxys egde] BLE codes?**
A: I had to do some deep googling to answer this one! lol

The beacons that make the droids react are non-standard beacons. Anything like our standard iBeacon protocol beacon or any other iBeacon here on Amazon will NOT work because we are all broadcasting the "Apple" manufacturer ID code at the beginning of our beacon broadcasts; also our broadcast format is standard iBeacon, not what you need. You need something that broadcasts a custom set of IDs; that can't be done with regular iBeacons. 

If you are a bit techy, you could use an ESP32 to accomplish this goal; you can order them here on Amazon for cheap. You would need to download a beacon sketch for it, and then customize the sketch to broadcast the custom IDs that the droids recognize. No guarantees, but I found some random person on the internet that said the following:

"You can try Manufacturer Id <0x0183>, with Manufacturer Data 0x-03-04-44-81-82-01 for an R-series, or 0x-03-04-44-81-82-02 for a BB-series.
Note that they're not actually beacons - they're advertised as a non-connectable BLE peripheral with no GATT services.
Also, the Droids have a timer in them to only react every few minutes, to stop them becoming to chatty as they walk around Batuu."

**Q: I'm looking for a device to use for presence detection in home assistant or hubitat. i saw someone did this. can post a link to your solution?**
A: Using these in conjunction with ESPRESENCE and Home assistant for precise room tracking of my devices. So far it's good (takes a few seconds to update usually).

These beacons are easy to set up and have great range. I’ve used them over several months for cresting proof-of-concept apps, and the batteries have held well above 95% the whole time.
